How to identify & Control Spiders

Are house spiders harmful?

While most spiders pose little or no danger to people, some species can deliver venomous bites that may cause medical issues. In the U.S., the two most common venomous spiders are the brown recluse, distinguished by the violin-shaped marking on the top of its cephalothorax, the body part consisting the spider’s fused together head and thorax. The other important venomous spider is the black widow, notable for the red hourglass shape on the underside of its jet-black abdomen.

Spiders are a diverse group of arthropods found throughout the world. Some species are tiny, while others, such as the tarantula, are very large. They are voracious predators, feeding on insects, other spiders and even small mammals and reptiles. Here are some basic biology facts about them:

  • 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.
  • They 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 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.

Frequently asked questions

Loose screens and cracks under doors, windows, and other openings are all possible entryways for a spider. These pests may move indoors while searching for food, mates, warmth, or moisture. The presence of insects and other prey in homes is a common reason for spiders to come inside. Spiders are also accidentally introduced inside homes via infested items such as plants, firewood, clothing, etc.

One of the most surefire ways of telling if you have a spider infestation is if you notice an abundance of webs in or around your property. An other sign is the presence of egg sacs. If you spot egg sacs in your home there’s a chance they could hatch, which would result in hundreds of baby spiders making their way around your home. Of course the most absolute sign of a spider infestation is actually seeing spiders. If you spot a spider crawling through your living space or work area, contact a pest control professional to ensure the infestation doesn’t grow worse.

Common house spiders can be easily controlled as part of a pest control program, so there is no need for pest control specifically for house spiders. However, for the more dangerous species, like brown-recluse spiders, pest control is absolutely necessary to prevent harm due to their poisonous bites.

The cost varies based on the species of spider. Brown recluse treatments can be fairly costly due to the procedures required to eradicate them. On the contrary, common house spiders are easily controlled as part of a pest control program for no extra cost.
