A Picture is worth a “Thousand Words”
I love this picture, this crack is about as thick as a credit card and this German Cockroach was making it’s way into it, without much difficulty. German Roaches love to have their top and bottoms of their bodies touching an object, it affords them comfort in knowing that they are out of sight and hidden. This is called Thigmotropic – The turning or bending response of an organism upon direct contact with a solid surface or object.
This isn’t the greatest picture but roaches and bugs are able to hide in the smallest of harborages, just think about the ability of Bed Bugs to hide behind baseboards and in dressers or just about any area in which they can flatten out and hide. Remember pests have adapted to us and have done so in remarkable a fashion, they can hide so well that it takes a true Professional to track them down.
