Spider Control
Spiders are one of the most-feared of all pests in the home that people want to exterminate. There are over 35,000 known spider species around the world, but only few are considered to be dangerous and 27 species are known to cause human fatalities There are more phobias about spiders than any other pest, and understandably so.
If you get bitten by the wrong spider – a black widow or a brown recluse – and you have a bad reaction to the venom, you can end up in the hospital. And yes, there have even been some deaths associated with spiders. Most spiders like moisture and are found in basements, crawl spaces, and other damp parts of home and offices. Others like dry, warm areas such as subfloor air vents, upper corners of rooms, and attics. They hide in dark areas.
Facts
- Spiders are arthropods, like insects – they have an exoskeleton that is on the outside of their body instead of the inside (unlike humans)
- There are around 40,000 known species of spider
- There are a few main differences between spiders and insects, and one of these is the number of legs – all spiders have eight legs
- Spiders create silk from spinneret glands in their abdomen
- Not all spiders catch their prey in webs – some hide and wait for insects to come by
- Spiders lay eggs, and store them in an egg sac to keep them safe.
Diseases/Threats
- Many spiders bite, but very few are a risk to humans
- The venom of black widow spiders is a neurotoxin (poisonous to the nervous system)
- The venom of brown recluse spiders causes necrosis (damage and breakdown) of skin and tissue
- Tarantulas have hairs on their body and hind legs that can pierce human skin and inject a toxin
- Most spider bites cause minor swelling, inflammation, and itching. However, bites from venomous spiders can cause more severe reactions
