We had another outstanding presentation from Lou Sorkin at the 10th edition of the New York Pest Expo. He was generous enough to share with us his knowledge and experience with spiders.

Spiders have only two body segments instead of three: a fused head and thorax (cephalothorax) and an abdomen. They have 8 legs and usually 8 eyes. They grab their food with the chelicerae. Some chelicerae are hollow and contain venom glands. They use these glands to inject venom into their prey. In the abdomen there are spinnerets. They produce the silk that spiders spin into a web and trap their prey.

At this year’s New York Pest Expo we were honored to have Dr. Bill Robinson of B&G Equipment share with us his insights on the Biology and Control of Household Spiders. He helped us learn more about the common species known to inhabit homes.

Spiders are everywhere and may be a health threat because every spider is venomous to a degree. Every spider can bite and will inject a foreign protein.  They are difficult to control because spiders don’t have tarsal pads like a cockroach and, therefore, a residual insecticide may not affect them.  Spiders are also seasonal. They are more prominent in the spring and fall.
