WHAT DO I NEED TO KNOW ABOUT SPIDERS?
Spiders are a diverse group of arthropods found throughout the world. Some species are tiny, while others, such as the tarantula, are very large. Although most common house spiders are harmless, widow spiders and brown recluse spiders are two common venomous types in the U.S.
Spiders are voracious predators, feeding on insects, other spiders and even small mammals and reptiles.
- They differ from insects in that they have two, rather than three body regions. These two regions are the cephalothorax — which contains the eyes, mouthparts and legs — and the abdomen.
- Spiders have four pairs of legs, while insects have three pairs of legs. They possess modified appendages called pedipalps located in the front by the mouth, which in some species resemble an extra set of legs.
- Most spiders have eight simple eyes located on the front of the cephalothorax, but some spiders have fewer eyes. The arrangement of these eyes is often used to distinguish between various species of spiders.
- The abdomen is unsegmented and contains the genital structures, spiracles and the spinnerets used to spin silk.
- Many types of spiders spin some type of web, and the shape or type of web is often as distinctive as the spider itself. Other spiders are active hunters that move about looking for prey, but they do not spin webs.
How Can I Prevent Spiders?
While you are likely to continue to still an occasional spider, there are lots of things that you can do to make your home less inviting to them. Make sure to keep all vegetation, woodpiles, and clutter away from the foundation of your home because they are all ideal spider environments. Also, avoid the use of landscaping materials such as riverbed rock as the rounded rocks create a damp cool environment that is favorable to the sorts of insects that spiders often eat. Switching to yellow (sodium vapor) lights can also reduce the number of insects attracted to your home. Lastly, you will want to keep your home as well sealed and free of moisture as possible. Accordingly, you will want to seal up gaps around windows and doors and any other entry points or cracks. Keeping your basement as dry as possible is also helpful.
