Arizona Pest Guide

Understanding Arizona Pests

Arizona's warm climate creates a pest-control challenge year-round. From venomous scorpions to destructive termites, the pests you'll encounter depend heavily on the season and your specific location. This guide covers the most common pests Arizona homeowners and businesses face, when they appear, how to prevent them, and when professional help is essential.

With bi-monthly pest control service, you can stay ahead of infestations before they become costly problems. The map above shows exactly where our technicians look and treat on every visit — next, explore Arizona's pest seasons and the most common invaders.

Season-by-Season Guide

Arizona pest seasons & common invaders

Pest pressure in Arizona follows the calendar. Pick a season to see what's most active around your home right now, how to prevent it, and when it's time to call us. We've started you on the current season.

Summer (Jun–Aug): Peak scorpion season — mosquitoes thrive after monsoon rain and wasps build nests under eaves.

4 pests to watch

Scorpions

Peak: April–October

Arizona's bark scorpions are small but venomous. They hide in dark, warm places and are most active during warmer months.

Prevention tips & when to call

Prevention Tips

  • Seal cracks and crevices around doors, windows, and baseboards
  • Remove piles of wood, rocks, and debris from your yard
  • Keep outdoor lights off or use yellow bulbs to reduce insect attraction
  • Declutter storage areas, closets, and garages
  • Use a blacklight at night to spot active scorpions

When to Call Upside

If you've seen multiple scorpions indoors, been stung, or have scorpions in high-traffic areas like bedrooms.

Mosquitoes

Worst: May–September (heat-dependent)

Arizona mosquitoes are disease vectors. They breed in standing water and are most active at dawn and dusk during warm months.

Prevention tips & when to call

Prevention Tips

  • Eliminate standing water (bird baths, clogged gutters, plant saucers)
  • Fix leaky outdoor faucets and sprinklers
  • Keep gutters clean and draining properly
  • Trim vegetation away from seating areas
  • Use screens on windows and doors

When to Call Upside

For large mosquito populations, standing water breeding grounds on your property, or health concerns.

Desert Pests (Centipedes, Tarantulas, Wasps)

Year-round; most active spring–fall

Arizona's desert environment hosts unique pests. Wasps nest on structures, centipedes enter homes for moisture, and tarantulas rarely pose danger but can startle.

Prevention tips & when to call

Prevention Tips

  • Seal gaps in walls, screens, and doors
  • Remove standing water and fix moisture issues
  • Keep vegetation trimmed away from the house
  • Remove nests and hives when small and safe
  • Declutter yards and remove hiding spots

When to Call Upside

Active nests near high-traffic areas, aggressive wasp behavior, or recurring indoor sightings of desert pests.

Fire Ants & Carpenter Ants

Year-round, worst: spring–fall

Fire ants are aggressive and deliver painful stings. Carpenter ants damage wood structures. Both species are common in Arizona and reproduce quickly.

Prevention tips & when to call

Prevention Tips

  • Eliminate standing water sources
  • Seal entry points around windows, doors, and utility lines
  • Keep food sealed and kitchen clean
  • Trim tree branches away from rooflines
  • Remove wood-to-soil contact around the foundation

When to Call Upside

If you have outdoor nests near play areas, indoor carpenter ant activity, or recurring ant infestations.

Service Questions

Common Questions

How often should I have pest control service?
We recommend bi-monthly service for most Arizona homes to maintain year-round protection as pest pressure changes seasonally. High-risk properties or pest-prone areas may benefit from monthly service.
What's the best time to treat for pests?
Prevention is key. Spring (March–April) is ideal to establish defenses before peak pest season. However, with bi-monthly service, we stay ahead of infestations year-round.
Are your treatments safe for pets and kids?
Yes. We use targeted, low-toxicity treatments applied strategically to problem areas. We'll provide guidance on keeping your family safe during and after service.
How long does it take to eliminate an infestation?
It depends on the pest and severity. Some pests need multiple treatments spaced weeks apart. We'll create a timeline based on your specific situation.
Do I need to leave my home during treatment?
Not always. Most of our treatments allow you to stay home. We'll advise you on any necessary precautions before we arrive.
