Encounters between people and spiders are usually accidental and bites are a response by the spider when its web or nest (or the spider itself) is disturbed. Most produce venom therefore, they could be considered “poisonous.” The venom is stored in glands that empty into the spider’s fangs or chelicerae. For the most part, spider bites are insignificant. However, just as bee and wasp stings may trigger allergic reactions in some people, the same can be true for spider bites. Young children, the elderly and hypersensitive individuals are more likely to react more strongly to a spider bite.
WHERE THEY HIDE
Web-building spiders are most likely to show up in areas where insects are abundant; e.g., woodpiles, around porch lights, windows or water sources (such as water spigots). On occasion, you will find them on objects or in areas that have been left undisturbed which may include sandboxes or even children’s toys. Check these items periodically.
Finding a large number of spiders indoors usually means that there is an ample supply of insects and other “spider food” in the area. Any real attempts to get rid of spiders should focus on eliminating the insects upon which spiders prey:
- Sanitation requires the reduction or elimination of conditions that attract insects; e.g., high moisture and ready access to food of some sort.
- Exclusion: Find the entry points used by both insects and spiders and seal or close these areas.
- Knocking down and removing webbing, or mechanically removing/killing the spiders.
- Vacuum the areas along baseboards, in corners and under and behind furniture.
- Clean bookshelves periodically.
If you’re concerned that more spiders will show up or hatch from an unseen egg sac (they probably will), then—if you know what you’re doing—you could carefully apply an insecticide along baseboards, in corners, and inside storage closets.
Crawlspaces are often attractive environments for spiders. Simply setting off foggers (“bug bombs”) is not likely to be effective and can be hazardous particularly if you contaminate your air-conditioning system. Crawlspace treatments are best left to pest-control professionals.
