alternatives to pesticides - bugs/pests - spiders


Actual size: 1/16” – 3/4”

Spiders are beneficial predators that consume many destructive insects. There are many types, but only black widow spiders and hobo spiders pose any threat to humans in our area. Hobo spiders build funnel shaped webs in crawl spaces, wood piles, or around the perimeters of homes. They rarely climb vertical surfaces and are uncommon above basements or ground level. They wait inside the tube and dash out to bite any prey that becomes entangled in the web. They can grow to 3/4” long and may bite intruders with little provocation. Bites are touch sensitive and cause a severe headache in the first several hours following the bite. Bites can be serious and should be treated.

Keep tall weeds and grasses away from the house. Shut basement and first floor windows tight or use screens. Make sure the bottoms of doors have insulation stripping that can keep spiders from entering. Avoid areas where spiders congregate.

Physical Control
The best way to get rid of a spider in your home is to place a glass jar over it, slip a card underneath and carry it outside. They are fragile and will usually be killed by sweeping with a broom. Spraying with a pesticide is usually pointless because woodpiles and similar areas are so attractive to spiders that they usually return.
