Whilst someone with a cockroach phobia could harbour the same emotions towards the humble spider, they in fact have very little in common with one another. Whilst cockroaches spread disease such as Salmonella, Staphylococcus and Streptococcus, most spiders are pretty harmless to humans. There are of course a few species of spider such as the infamous Black Widow which can cause fatal bites. But even most Tarantula species pose no threat to human life. Deaths from spider bites are rare while illnesses spread by cockroaches remain rife. Those spiders that we find living in our homes are harmless.
Geographically cockroaches are mainly found in tropical and subtropical locations with the exception of the rule being German, American and Oriental which have evolved and adapted themselves to live within human habitats. But spiders are found all over the world in every continent except in Antarctica where there are none.
There are further studies into the fact that our children have become detached from the natural world – spending more time inside on their Playstation than outside in the garden. It has a name ‘nature deficit disorder’ and the detachment from the natural world literally increases our fear – including that of insects and arachnids.
However there are a few reasons to really like spiders. If you find a spider in your home this is a good sign because there would be thousands of other bugs that you would not want in your home if the spider wasn’t there. The spider is keeping your house clean which is why people often think of the spider as a ‘clean’ creature. The same applies to your garden where they will keep the pest population reduced for you. Lastly, spiders are a sign of good luck in many cultures all over the world.
