Hiking the Caribbean: Spiders

Monday, August 15th, 2011

In general, spiders are quite helpful creatures. They feed on insects us humans find bothersome, such as flies and mosquitoes. Unfortunately spiders have gained a negative reputation because of their creepy appearance. Spiders found on the islands of the Caribbean are even more feared by travelers simply because of their larger size and unfamiliarity. Anyone planning to travel to the Caribbean and enjoy some hiking in the wonderfully beautiful countryside should take note of the spiders listed below.

Orb Weavers is a class of spider that is found on all the continents, as well as the islands of the Caribbean. They have eight eyes, hairy or spiny legs and many are quite brightly coloured. Some varieties do not spin webs at all, but actually produce sticky balls which they hang from their front legs in an effort to attract male moths. Once a moth is caught on the gummy surface of the ball, the spider reels it in and begins eating the moth. Those species that do weave webs create incredible sticky spiral webs that stand vertically in the branches of trees. The center spiral is, of course, meant to catch, bite and wrap prey in preparation for eating. At the end of each day, when the sun begins to descend, an orb weaver will consume its web. After resting for a while, it will then build a new web.

Black widow spiders do reside in North and South America, and the Caribbean islands. They can be identified by their eight black legs protruding from a black body with a bulbous back end. The back part of the body will be marked with either a red hourglass, red spots, red stripes and sometimes white lines surrounding the red markings. Some species of black widow are aggressive, but bites only usually occur when the spider is protecting an egg sack, or a finger is stuck in a web and mistaken for prey. The female black widow bite is the nastiest, but they can be avoided. Black widows like dark places amongst fallen vegetation, so when hiking keep to the trails.

Tarantulas can be found on the islands of the Caribbean, but don’t let that stop any plans from visiting! They may have a threatening appearance, in fact it is downright spine-chilling, but there is no tarantula known to have a bite deadly to humans. Those species found in the Americas in particular, have urticating hairs on their underside which the spider will throw as a first line of defence. The hairs are irritating to sensitive areas like nasal cavities, the mouth, eyes, and ears. Generally a curious animal sniffing around a tarantula will end up with a painful snout full of urticating hairs, but unless a hiker plans to sniff the ground as they walk, it is unlikely a human will be affected.

Hiking the wilderness of a foreign country can be an exciting experience! There are so many different species of birds, plants, trees and wildlife for the avid outdoors enthusiast to appreciate. Even those travelers who are knew to the hiking hobby will enjoy the Caribbean. The region offers a colourful canvas of nature to photograph, document and remember for a lifetime.

Hiking the Caribbean: Bug Juice

Saturday, August 13th, 2011

Insects inhabit almost every inch of the planet, and each one serves a beneficial purpose. Conflict between humans and insects arises when the insect world collides with ours. Outdoor activities such as camping, hiking, cycling, and bird watching are often the beginning of a never ending battle between homo sapien and arthropods. So we, as self-preserving human beings, look for ways to protect ourselves. Bug repellent is usually the top of the list, but which one? Walk into any drug store or outdoors supplier and there are dozens of brands to choose from. Let’s try to make some sense of them all.

To begin, the best way to start your multi-layered defence against bug bites is wearing socks. It may seem crazy to wear another layer of clothing in a tropical climate, but it is a choice between hot feet with no bites or cool feet covered in bites. Also, consider investing in a technical lightweight long sleeved hiking shirt. There have been some great advances in fabric technology, making it possible to wear light garments that actually work to cool the body, despite being covered and in a hot place. Plus, there is the added benefit of armouring oneself against bug bites!

There are many different insects that call the Caribbean region their home, including the mosquito. They like warm, damp areas so if you plan on hiking in the jungle areas then be prepared. Higher altitudes are less populated with the little bloodsucker. They are attracted to bright colours such as pink, red, orange and white. Wearing colours like brown, grey and black will at least not appeal to mosquitoes. They also like the smell of sweat, particularly that of individuals who excrete a large amount of lactic acid after exercising. Female mosquitoes can detect carbon dioxide in our breath and view it as a possible blood source.

N,N-Diethyl-meta-toluamide or DEET is a yellow oil used in insect repellents and is recorded by the National Outdoor Leadership School as the single most effective product on the market. Generally the concentration of DEET in repellents is 20% to 30%, any more than that and there are adverse effects on the wearer. The chemical is very useful, but it is also very poisonous and should be worn directly on the skin. Like any repellent, DEET products should be sprayed on clothing and definitely not on skin that will be under clothing. Lemon eucalyptus is a great non-chemical alternative to DEET. It works better than citronella, and only needs to be re-applied every two hours.

Protecting oneself from insect attack takes more than one defence. It takes research, planning and patience. While vacationing in the Caribbean, make sure to pack the bug-defending necessities so your time away isn’t eaten up by ravenous critters just waiting for a new flavour of blood!

The Dreadful Effects Of Malaria

Thursday, June 16th, 2011

Malaria, a mosquito-borne disease caused by mosquito bites that carry a parasite of the genus Plasmodium, is widely common in tropical and subtropical countries in Asia, South and Central America and the Middle East. Malaria is more prevalent in regions with lots of rainfall and constant high temperatures that supply the perfect conditions for bugs to thrive and multiply.

Malarial attacks begin with multiplication of the plasmodium virus in the red blood cells and could have long-lasting and even deadly consequences.

Malaria starts with headaches, fever and chills and could, in later stages, also lead to coma. Malaria has 3 stages, the first stage starting with fever, shivering, joint pain, vomiting, anemia, hemoglobinuria, retinal injury and fits.

This could occur for 4 to 6 hours every other day, every three days or might happen every four days. As the disease progresses into the second stage, one could experience feelings of heat and dryness, whilst the third stage could result in extreme fatigue and weakness.

It is however worth noting that the first indications occur about 10 to 15 days after the mosquito bite when it multiplies and bursts the red blood cells.

The effects of malaria especially in children may not be ignored because a bite from this insect can lead to high intracranial pressure that shows up as abnormal posture caused by acute brain injury.

Malaria caused by mosquito bites could lead to other significant consequences like cognitive impairment, widespread anaemia and neurological impairment with cerebral malaria. Cerebral malaria could result in retinal whitening that is the foremost distinguishing clinical sign of malaria.

Malaria caused by mosquitoes could in severe cases show up as an enlarged spleen, severe headache, clots of blood in the brain, inflamed liver, low blood sugar and hemoglobinuria which could lead to renal failure.

Other significant side effects caused by this mosquito bite disease could be dehydration, liver or kidney failure and breathing problems caused by fluid in the lungs.

Rupture of the spleen might lead to internal bleeding with the spread of infection leading to inflammation of the meninges, or membranes, that enclose the brain and spinal cord.

The control of malaria begins with the use of mosquito nets, the use of insect repellents and the spraying of insecticides in places where mosquitoes could breed easily.

Home pest control starts with not having water standing about in buckets, tubs and the spraying of insecticides in drains which are perfect breeding grounds for mosquitoes.

Mosquito repellents could be chemical based or could also be in the form of herbal or biological pest control with the planting of mosquito repellent plants in the environment.

It is best to note that one way of pest control lies in protecting oneself from mosquito bites by avoiding going out at dawn and dusk. It pays to have mosquito mesh on all the doors and windows at home. Avoiding wearing dark colors and opting for long sleeved shirts and long trousers would also help.

Pest control includes using repellents like creams, lotions and electronic devices. It is best to kill mosquitoes by spraying insecticides, but this ought to be done some time before entering the room. Last but not least, preventing mosquito bites is the most effective pest control each time.

How To Remove Bed Bugs From Your Clothes

Saturday, June 4th, 2011

Bed bugs used to be a part of eveyone’s daily life before the Second World War – or should that be ‘a part of everyone’s nocturnal life’? For hundreds of years, people just grinned and bore it; they had to because there were no effectual ways of getting rid of them.

They lived in the stored clothes, the furniture, the bedding and the houses of the rich and poor alike and because houses were located so close together, families were larger and people were in and out of each others houses, you could not eradicate a bed bug infestation for long.

Then came the bombing of European cities in the Second World War 1939-1945 and many inner cities were unsafe, so the authorities decided to take the opportunity to level the inner city slums and begin again. An equivalent programme was started in America, but not because of bombing.

The authorities pulled down hundreds of millions of houses and made billions of rats, mice, bed bugs, fleas and other nasties homeless. In fact, rat poison and a new wonder insecticide, DDT, were used widely in the clean up. By the end of the Forties or during the Fifties, bed bugs were just about eradicated from the Western World.

The Baby Boomer generation was the first one never to have been bothered by bed bugs. This happy situation lasted until the mid-Nineties, when increased long haul travel and increased immigration allowed bed bugs to hitch lifts back to the West. These undesirable hitch hikers mostly returned on clothing that had been packed away in suitcases.

And so here we are today, in a state of affairs where the West’s major inner cities have a bed bug problem of epidemic proportions. Bed bugs are being passed around from person to person on all forms of public transport but particularly buses, trains and taxis and anywhere where individuals congregate, but particularly hotels, cinemas and waiting rooms.

So, here are a couple of tips on how to avoid infesting your home with bed bugs. If you stay in hotels a few nights or one night at a time, just unpack what you need to at any one time. In other words, live out of your suitcase.

If you are on a longer holiday, by all means, take out everything, but keep your suitcase closed and have all your clothes boil washed, dry cleaned or tumble-dried on ‘HOT’ before you repack them to go home.

If this cannot be done because of the sort of fabric, inspect all the seams, hems, pockets, cuffs and collars and blow them with the hair-dryer on ‘HOT’. The hair-dryer is not quite as effective, but all stages of a bed bug’s life cycle are killed by seven minutes exposure to temperatures above 45C or 115F.

If you cannot heat-treat your clothing before you leave the hotel, seal them up in plastic bags and treat them when you arrive home – preferably in a laundrette or dry cleaners.

What do you do about your overcoat, if you mingle with people each day on the bus or at work? This is a difficult one. Bed bugs are resistant to all forms of insect killer, which is why we are having this epidemic, so you will literally have to inspect your overcoat each time you come home or buy one that you can put in the tumble-dryer every night.

One bed bug can lay 300 eggs and last for a year without feeding, so you cannot know that you have not got bed bugs, you can just say that you have not seen any – yet.

Unusual Uses for the Indoor Bug Zapper

Wednesday, May 11th, 2011

I don’t know whether you have ever used a handheld, indoor bug zapper, but I think that they are wonderful. I?m talking about the handheld sort that looks like a child’s plastic, toy tennis racquet. They come in two basic sorts. I rather the rechargeable bug zapper, for the reason that batteries end up up costing more than the indoor bug zapper itself, although you could always buy rechargeable batteries, but then they are costly too.

My wife and I like to pass time in the garden. We meet friends there, lunch there and generally laze about outdoors, as do most folks around here, when they are not working. What’s more, it’s far cooler outdoors than indoors. A comfy chair, a few snacks, a chilled drink and a book or a friend and life does not get much better. In fact, it?s heavenly.

That is until about six or seven o’clock when the first squadron of mosquitoes have judged that the sun’s rays have lost enough strength that they will not evaporate and they come out searching for blood. Some evenings are worse than others, of course. Normally, the mosquitoes are quite bearable, particularly since I have discovered the indoor bug zapper. (I don’t know why it is called an ‘indoor bug zapper’, it is just as effective outdoors as in)..

It’s not that I want to kill things, but I find it hard to have consideration for mosquitoes. Nonetheless, I do get a definite amount of pleasure from seeing and hearing mosquitoes and other bugs literally blow up with a flash and a zap as they come into connection with the charged and ground wires of the indoor bug zapper. These electric bug zappers are capable of packing quite a charge, particularly if the batteries are new or the pack is wholly charged.

The other day, I discovered a new use for my handheld, indoor bug zapper. I’ll tell you how it came about. I was in the garden, as normal, and my bug zapper was close at hand as the first squadron of mosquitoes was expected. I had my book in one hand and the bug zapper on my lap, when my wife asked me to go to the shop for her. No problem, therefore, I set off on the five minute walk.

I was half-way there when I noticed that I had the indoor bug zapper in my hand, but it was not worth taking it home and beginning the trip again. Anyway, on my return trip, I had my small bag of groceries in one hand and the indoor bug zapper in the other, when a local bully of a dog came running out of a garden straight for me. This has occurred often and, although he has never bitten me yet, it is somewhat intimidating. He stood there glaring at me with teeth bared and his ‘pack’ of assorted neighborhood friends came out to surround me and join in.

I don’t really know what the best course of action is in this position. I have tried holding my position, but the threat just continues and I have tried to keep walking, but he gets terrifyingly close by on occasion. This time, I unexpectedly lashed out with the indoor bug zapper and just hit him on the nose. Well, I’m not sure if it hurt him, it did not appear to too much, but it gave him a very nasty shock in more ways than one, I can tell you! He jumped about four feet into the air as if he were on a pogo stick and then ran for all he was worth with all his pals behind him. It was very gratifying after six months of aggravation from this dog.

Anyway, I don’t take my indoor bug zapper everywhere with me, but I will in future, if any further local dogs bother me. I know it works a treat. I have seen that one since, but he stays far away from me and doesn’t utter a squeak. I think I would take my indoor bug zapper with me, if I were wandering in an strange part of town or the park nevertheless.

Electric Bug Zapper

Tuesday, April 26th, 2011

If you aren’t already familiar with the hand held bug killer, you are really going to like it and if you have used one before, I’m sure you’ll welcome it back like an old friend! The hand held insect killer does just what it says: it zaps bugs. But it does it really, really well.

Any bug that comes into contact with the electronic bug killer is fried. Smaller insects like gnats and mosquitoes are vaporized with a very pleasing flash and a crack. Larger insect, like house flies and wasps die, but don’t explode like the smaller ones.

Think about it, how many times have these flying bugs taken the edge off an otherwise lovely evening in the garden? Or how many times have you not been able to get a good night’s sleep, because you know there’s at least one mosquito in the bedroom. It has happened to me dozens and dozens of times, I know! It is very satisfying to get your revenge with the hand held insect zapper.

I don’t like killing things unnecessarily – I’m married to a Buddhist- but mosquitoes? I’m sorry, they have to go. And the handheld bug zapper dispatches them without any more ado. No waiting and hoping they’ll fly into the ultraviolet light and into the mesh. No, one sweep of the hand held bug killer and the mosie’s gone and you can hear whether you got her or not. (I say her, because the sucking mosquitoes always are females – I assure you, I wasn’t being sexist).

Basically, there are two types of handheld bug zapper. There is the battery operated bug zapper and the rechargeable electric bug zapper. Both operate on the same principle, but I prefer the rechargeable type, although I guess you could use rechargeable batteries too. However, I think that they would be more expensive that the bug zapper in the first place. Anyway, I have had a handheld insect killer of the rechargeable sort for five years and I am very happy with them.

Nowadays, I spend a lot of time in Thailand with my wife, so you can bet your bottom dollar that I give my hand held bug killer a good work-out practically every evening. We usually eat in the garden in the evening and all socializing is done outside by tradition, especially in the rural areas, where we live. So it comes in very handy. I also use my electric bug zapper to ’sweep’ the bedroom for bugs before we go to sleep at night. Just like an FBI agent.

The electric insect zapper just seems to improve every time I buy one, which makes it difficult to give you definite specifications. The electric bug zappers I had four or five years ago, sometimes failed within six to nine months of purchase, although their ability to store a charge reduced a lot after four or five months.

However, the latest electronic insect zapper will easily last 9-12 months and still be very pokey after nine months. My newest one even has a strong light called a headlamp incorporated into it. I’m not certain what it’s supposed to be for, but if you think that vengeance is sweet, you can lure mosquitoes with it and then zap them with your electric insect killer.

Common Indoor Bugs

Friday, March 11th, 2011

Some of the most common indoor bugs we see all over the world are flies, spiders, fleas and beetles. Nobody likes to see a bug indoors, so most people will go to almost any extremes to get rid of these common indoor bugs. The less common indoor bugs may be woodlice, earwigs, scorpions and millipedes or centipedes, although they are no less wanted.

It does not matter where you live in the world, it is very hard to keep these common indoor bugs outside, unless you go to the extremes of keeping all your windows and doors shut at all times, which is obviously impossible. I live in Thailand and I know that this is not an option.

So, just what can you do about it? Well, let’s sort out all the flying insects first, as of all the common indoor bugs, I find them the most unpleasant indoor bug. They are very irritating, buzzing around your head and mosquitoes and other flies can produce painful sores and besides that, all flies spread disease. I hate to see them walking on food, knowing that they have more than likely just come off some dung heap somewhere and now they are spitting on my food to taste it with their stinking feet!

My first line of defence is fine-mesh door and widow screens. They are not expensive and can be added retrospectively to any window. My window meshes slide, so they can protect only one half of the window at a any one time, but I do not think that’s a problem. You can still set up cross-winds, by opening two or more windows at opposing sides of a room. I love to see the flies on the mesh struggling to get in by day and the mosquitoes doing the same by night. At night, it is wise to switch on as little light indoors as possible so as not to draw these common indoor bugs.

My second line of defence is natural predators – lizards, like Geckos (Jin Jok, in Thai). Some people don’t like them in the house either. I can’t say I’m all that keen on them indoors myself, but they are hard to keep out and they do consume hundreds, if not thousands, of indoor bugs every day. I like to see them lying in wait on the outside of the mesh, ready to pounce on any bug trying to wriggle its way through the mesh.

My third line of defence is a handheld bug zapper. You know, the electric, handheld bug zapper that looks like a toy tennis racquet. The come in two forms: battery and rechargeable kinds. They are brilliant at trapping and annihilating any flying bug. The inset literally explodes and vaporizes on contact with the fully-charged wires of the indoor bug zapper. If you haven’t tried using one, you really ought to. They are most satisfying. These three defences will keep your house quite much free of flies.

The crawling common indoor bugs are less of a problem really. Door screens on springs will keep 95% of them out and the Geckos will help too. Spiders can get in pretty easily, but then, I don’t mind them too much as long as they keep out of my way, as they consume other insects too. They are on our side to be honest. However, for those who can not bear to catch them and put them outside, the handheld indoor bug zapper works a treat on spiders too.

Sometimes, Fleas can be a problem, if you have cats or dogs, but then if you wash or dust the animal once a month, you should be able to keep these common indoor bugs under control quite easily. However, there are two final measures that we use. Every week, before we go out for the day, we spray every room with fly killer and every six-months we spray any rugs or carpets with an insect killer containing permethrin, which will survive washing and vacuuming for that long without losing its ability to kill common indoor bugs on contact. If you follow these methods, you should be able to keep your home or office quite free of the most common indoor bugs and the less common indoor bug too.

Natural Mosquito Repellents

Wednesday, March 9th, 2011

We all know that mosquitoes are pests. None of us likes being bitten by them. Most people say ‘bitten’ although this not true. ‘Stung’ is also not factual. What the mosquito is really doing is taking some of your protein in the form of blood though her proboscis, so that her eggs will have something to feed upon while they are developing.

In consequence, your blood is supplying the albumen (the ‘white’) of the mosquitoes’ eggs. It therefore follows that it is only the female mosquito that ‘bites’. In the course of sucking your blood, the mosquito squirts some juices into you. It is not fully understood what these liquids contain, but one is an anti-coagulant to keep your blood fluid and another might be a pain-killer so you do not feel the proboscis entering your pore. Some think that there might also be an antiseptic, but it is not accepted by every one.

Some mosquitoes also introduce other parasites into you, which can cause diseases like malaria, dengue, yellow fever and Japanese jungle encephalopathy. Mosquitoes are to blame for killing millions of people every year. Luckily the fluid that they inject comes from another source other than where they store the blood they have already taken, otherwise they could spread AIDS as well.

Having said all that, another indirect cause for alarm is in the deterrence of mosquito bites. The single most effective method of preventing mosquitoes landing on you is spreading mosquito repellent on your skin, and the most effective mosquito repellents contain DEET. However, it is now considered that the frequent use of DEET can cause neurological issues. Consequently, it worth looking for natural mosquito repellents.

Regrettably, there is no mosquito repellent as reliable as DEET, but some combinations of treatments are nearly as effective. For example, some people say that mosquitoes are drawn to people who have eaten bananas, so you could avoid bananas if you are nearby mosquitoes. Others say that mosquitoes are less likely to go for people who have eaten garlic or Yeastvite or Bovril.

Mosquitoes abhor the smell of lemons, so a local application of lemon juice is very efficient although the effect only lasts about thirty or forty minutes. However, there is a plant called the citronella and this deters mosquitoes equally as well. The citronella does not smell of lemons unless it is disturbed, but then it is very aromatic.

Grow them in pots on your window cills, on your deck or on your patio. The wind blowing through them is enough to release the smell. You can also collect the dead leaves and put them in your pillow. You could also rub green leaves directly onto your skin.

There are quite a few natural mosquito repellents, but they do not all work for everybody and nobody understands why. One theory is that diet and alcohol affect your appeal to mosquitoes. It is also possible that mosquitoes in different regions like different kinds of people, so it is always worth asking for local advice.
