Camel spiders dwell in deserts in the southwest United States. Generally, a noticeable increase in the number of spiders around your property indicates seasonal activity related to mating, so you'll see fewer spiders as the mating period subsides. If the spider count around your home is unbearable, you can take some measures to reduce their presence. Liquid chemical pesticides purchased at the grocery or hardware store may not work on arachnids. Such pesticides might kill spiders if you pour the chemicals directly onto the them, but other spiders will quickly move in and repopulate the area. Spider egg sacs can also survive pesticide applications. Camel spiders feed on insects and scorpions, so controlling a spider infestation will require reducing the presence of other pests in and around your home.
Things You'll Need
- Sticky traps
- Pest-control dust or microcapsules
- Chemical spider repellent
- Self-adhering weatherstripping
- Draft guards
- Plastic clothes-storage bags
Finding the Spiders
Place sticky traps in corners and under furniture around your home to determine if camel spiders are living inside, and if they're dwelling there in significant numbers.
Sweep or vacuum seldom-used rooms and closets, paying particular attention to corners and creases where the wall meets the floor.
Reinspect the same spaces a few hours later for signs of fresh spider activity.
Controlling the Spiders
Kill any moving camel spiders you find on your reinspection.
Apply pest-control dust or microcapsules in all cracks and crevices in your home, particularly in lightly used areas outside your typical traffic patterns.
Remove vegetation and trash, where camel spiders can lurk, from around your house's foundation, doorways and window wells.
Apply insect and scorpion repellent around your house, particularly at windows, doors, and other areas that offer spiders an easy way into the house.
Caulk any cracks, gaps, or joints around window frames and door frames to keep camel spiders from entering your home.
Apply self-adhering weatherstripping to doorjambs to seal gaps between the door and the door frame.
Slip a draft guard onto the bottom of your doors to eliminate gaps between the floor and the door.
Eliminate clutter, including boxes and clothes, in your basement and attic. Keep boxes and other items off the floor and away from walls to reduce hiding places for camel spiders.
A week or two later, treat your home once more with pest-control dust and insect repellent to limit or prevent new infestations.
Tips & Warnings
- If you have an insect or scorpion infestation that is out of control, you may need to call a professional pest exterminator to eliminate the bugs before you can take control of your spider problem.
- Be careful when picking up items off the floor, such as clothing, after you've launched your spider-control effort. Spiders may move around and hide in new places as they look to avoid pesticides and repellents.
