Spiders of all varieties and sizes are a common pest and major nuisance in many Omaha homes. Spiders have eight legs and most species build webs to capture their prey. Most spiders are passive hunters and need their prey to be caught in their webs. The majority of spider species aren’t likely to cause huge infestations, but even having a few in your home may be an issue for you. Spider infestations are commonly found in basements and garages, so our pest control treatment is generally focused in these areas of low activity.
Spiders in the Omaha area:
- Brown recluse spider
- Wolf Spider
- Hobo spider
- Cellar spider
- Jumping spider
- Yellow sack spider
- Daddy long legs
Most spiders are not aggressive. Bites are defensive in nature and result only when the spider is trapped against the skin. If a bite is suspected or is known to have occurred, follow these first aid steps recommended by the American Red Cross:
- Treat the site of the bite with an antiseptic to prevent infection.
- Apply ice to the site of the bite to reduce pain and swelling.
- If a black widow or brown recluse spider is suspected, or if serious symptoms develop such as increasing pain or swelling, consult a physician.
If at all possible, bring the spider to the physician’s office. Effective antivenins may be available, but they can only be used if the spider that inflicted the bite is positively identified.
It should be stressed that spider bites are difficult to diagnose correctly as there are many other medical conditions that mimic the same symptoms. Spider bites, particularly those of “brown recluse spiders,” are greatly over-diagnosed.
What to do:
From a biological standpoint, it is rarely necessary to control spiders, but most people would still prefer a spider-free home. A combination approach of sanitation and pesticides is usually effective. Pesticides alone, without some effort to remove or modify favorable spider habitats, will not be effective.
Remove rocks, wood piles, compost piles, old boards, and other sheltering sites adjacent to the home. Eliminate migration of spiders into homes by caulking cracks and crevices around the foundation and make sure all screens and doors are sealed tight. Keep crawl spaces free of debris. Limit boxes and other potential hiding places from basements and other dark storage areas. Regularly vacuum or brush spider webs. The management of other insect pests that are prey will help, too.
Occasional spiders can be removed by hand (wear gloves or grasp the spider with a tissue) or with a vacuum. Bug-bombs & foggers will have little effect on spiders.
Where spiders and webbing occur in nuisance numbers on the outside of buildings they can be washed off with a forceful jet of water. Reduction of outdoor lighting or replacing lighting with yellow or sodium vapor lights that are not attractive to insects will help to limit spider web building. Dark colored siding seems to be less attractive than white siding to the insects on which spiders feed.
