Most people dealing with spiders in an Arizona home don’t want a chemistry lesson. They want the spiders gone, they don’t want to use anything that could harm their kids or pets, and they want the fix to last longer than a week.
Here’s a practical look at what actually works, starting with what you can do yourself and getting into when it makes sense to call someone.
Home Remedies for Spiders
Home remedies are worth trying for minor spider activity, and a few of them genuinely help. The important thing is being honest about what they can and can’t do.
Natural Spider Extermination

Peppermint oil gets recommended a lot, and there’s some basis for it. Spiders sense their environment through receptors on their legs, and strong scents like peppermint disrupt that. A diluted spray along baseboards and entry points can reduce traffic in those areas.
It’s not a long-term solution. The scent dissipates, it doesn’t affect existing populations, and it won’t reach any eggs or harborage areas you don’t know about.
Vinegar works on a similar principle. Diluted white vinegar applied around door thresholds and window frames creates a surface spiders tend to avoid. Reapplication is needed to keep it active.
The most durable thing you can do yourself is seal the obvious entry points. A tube of caulk around window frames, door gaps, and utility penetrations does more lasting work than any spray. Pair that with cleaning out the garage or storage areas where spiders typically nest and you’ve removed two of the three things keeping them around.
DIY steps worth trying:
- Peppermint oil spray along baseboards and window frames
- Diluted white vinegar applied around entry points and door thresholds
- Caulking and weather stripping to seal gaps in the exterior
- Clearing clutter from garages, closets, and storage areas where spiders hide
Does Spider Extermination Work?
Professional extermination works differently than home remedies, and not just in degree. It targets spiders at the population level rather than discouraging individuals. For venomous species especially, that distinction matters.
Black Widow Extermination Tips
Black widows are not a peppermint-spray situation. They live in spots most homeowners don’t check: inside outdoor electrical boxes, tucked under landscape rock, along the back wall of a garage, deep in a woodpile.
The Arizona Poison and Drug Information Center reports that black widows are among the leading causes of serious spider bites in Arizona, with children and elderly adults at higher risk of significant symptoms.
A professional treatment identifies where they’re nesting, applies residual products in those harborage zones, and removes webs and egg sacs so the population is disrupted rather than just driven to a different corner of the property.
There’s also the food source question. Black widows follow insects. If crickets are active around your foundation after dark, black widows will be too. Treating only for spiders without addressing what they eat is how the problem keeps coming back.
When to Call a Spider Pro
Not every spider in the house means you need a service call. One cellar spider in the bathroom is not a crisis. But there’s a short list of situations where calling a professional is the clearly smarter move.
Signs You Need an Exterminator
The straightforward one: you’ve found a black widow or you suspect you have desert recluse activity. These are medically significant species, the bites can require treatment, and eliminating them properly requires products and methods not available over the counter.
The less obvious one: you’ve been treating on your own and it’s not working. If you’re spraying regularly and still finding spiders inside, the infestation is being fed by something you haven’t addressed. A professional can find it.
Ongoing service is what keeps results from slipping. Arizona’s climate means spiders don’t go dormant the way they do in colder states. Without a maintained perimeter, new populations move in and the cycle starts again.
Signs it’s time to stop DIY-ing it:
- You’ve found black widows or suspect recluse spiders in or around the home
- Spiders are still showing up indoors despite consistent treatment efforts
- Webs are being rebuilt in the same spots faster than you can remove them
- You’re finding egg sacs, which means a breeding population is already established
