Why Arizona’s Heat Drives Pests Indoors
Spiders and scorpions are generally content to stay outside. They hunt at night and hide during the day in dark, secluded areas—often under rocks, debris, or logs. In summer, when insect activity is high, they typically have plenty to eat.
But when temperatures soar, even these heat-adapted pests may retreat indoors in search of cooler conditions. Climate-controlled homes offer relief from extreme heat, and if the weather is especially dry, spiders and scorpions may also come inside looking for water.
In Phoenix, it’s fairly easy for these pests to get in. All it takes is a small crack, gap, or unsealed opening. Once inside, they’ll look for cool, dark, and undisturbed spots—like closets, bathrooms, basements, or storage areas.
Scorpions vs. Spiders: Which Are More Dangerous?
The level of danger spiders and scorpions pose depends on the species. Most spiders in Arizona are harmless, but two venomous types live in the Phoenix area: the black widow and the brown recluse. Both are shy and tend to avoid people, but they will bite if threatened.
The bark scorpion is Arizona's most venomous scorpion. Its sting can cause intense pain and, in some cases, severe reactions, especially in children or those with allergies.
Because both venomous spiders and scorpions are active in the Phoenix region, it’s safest to steer clear unless you know exactly what you're dealing with.
Signs You Have a Spider or Scorpion Problem
Being able to spot early signs of an infestation can help you take action before it gets worse. Keep an eye out for:
- Nighttime sightings: Both spiders and scorpions are nocturnal. Scorpions also glow under a blacklight, which can make them easier to find at night.
- Egg sacs: Spiders lay their eggs in silken sacs, which they may carry or stash in hidden areas.
- Webs: Many spiders build webs to catch prey. An increasing number of abandoned or active webs could signal a larger problem.
- Shed skins: Scorpions molt as they grow. Finding cast-off exoskeletons can indicate an infestation.
- Frequent sightings indoors: Repeated appearances of spiders or scorpions in your bathroom, garage, or closets likely mean you’ve got an issue.
How to Protect Your Home and Family From Arachnids
Keeping spiders and scorpions (yes, they’re both arachnids) out helps protect your home and your family. Try these tips to make your house less inviting:
- Seal up cracks, gaps, and openings around your home’s exterior.
- Install and maintain screens on windows and door sweeps.
- Remove outdoor clutter, firewood piles, and yard debris.
- Declutter inside your home to reduce hiding spots.
- Add weather stripping and screen your vents.
- Turn off outdoor lights at night—bright lights attract insects, which in turn attract spiders and scorpions.
- Reduce excess moisture around your home.
- Address any existing insect infestations that could be attracting either pest.
