To get rid of spiders, follow these 4 steps:
- Eliminate the food source - Spiders are attracted to properties where their insect prey live. They will go elsewhere if there is nothing for them to eat. Change exterior lights to yellow lights that don’t attract flying insects. Adjust flood lights and indoor light timers so they don’t pull night-flying insects directly to the home or business. Seal cracks, crevices and broken screens that let insects (and spiders) get indoors.
- Physical removal – Use a HEPA vacuum or broom to remove spiders, webs and egg sacs from indoor and outdoor areas. The more egg sacs you remove, the fewer spiders you’ll have in the future.
- Eliminate potential nesting sites – Make spaces less hospitable to spiders. Tape up boxes and store them off the ground. Eliminate clutter in garages, sheds, attics, basements and crawlspaces. At commercial properties, replace vegetation around the exterior perimeter with an 18-inch-wide swath of gravel to eliminate spider (and spider prey) hiding places. Reduce humidity in basements and crawlspaces by improving ventilation.
- Use the best pest control products for spiders – A combination of products can help eliminate spiders from your home, cottage or business:
- Diatomaceous earth (DE) or exterminator dust – This natural desiccant will kill spiders by drying them out. Apply it to cracks, crevices, corners and near outdoor lights where spiders are active using a bulb duster or Longshot Duster. The spiders walk through the DE, which scratches the waxy outer layer of their exoskeleton. This causes the spider to dry out and die.
- Crawling insect monitors and glue traps – Place monitors or glue traps behind furniture, among storage boxes, in garages and boat houses lets you catch the crawling insects that spiders eat and the spiders that actively hunt, such wolf spiders and fishing spiders.
- Insecticide sprays – Repellent aerosols and sprays kill spiders on contact. Also apply them to exterior cracks and crevices where funnel-shaped spider webs exist to flush out spiders, which you then can squash with a putty knife.
