If you are also currently living anywhere in Phoenix or Arizona, you know summer isn’t just hot. They could be hostile, too. It’s crazy how triple-digit heat and sudden monsoon storms can make pests desperate. It’s nothing new to you to hear scorpions on the doorways. Scattered roaches in the bathroom. Mosquitoes multiply in the yard. Now, it makes sense to get a seasonal pest prevention plan when living in desert climates. In this guide, we will explain the actionable steps to control pests during summer. As well as how to treat your home and how professional exterminators can get rid of them.
Why Desert Summers Are Prime Time for Pest Problems
Phoenix summers create the perfect storm for pest activity. Opposite to the temperate regions, the desert heat doesn’t even kill pests. Instead, it pushes them indoors.
- Extreme heat encourages pests to seek places for shade and coolness, which is inside your house.
- Monsoon rains can result in flooding their nests and flushing pests such as roaches and ants.
- Warm nights keep pests active after dark, including scorpions, mosquitoes, and spiders.
Common summer pests in the Phoenix area include:
- Bark scorpions (most active at night and around block walls or shaded rocks)
- American and German cockroaches (often found in bathrooms, laundry rooms, and storm drains)
- Mosquitoes (especially after watering the lawn or a monsoon storm)
- Ants and spiders (in search of food and moisture)
Smart Summer Pest Prevention Tips for Desert Homes
Keeping pests out in summer starts with blocking their favorite entry points and making your home less appealing.
Seal and Secure Your Home
- Use caulk or weather stripping to close gaps in windows, baseboards, and door frames.
- Install door sweeps under entry doors and garage doors.
- Repair or replace torn window screens.
Reduce Moisture Indoors and Out
- Repair any leaky faucets, irrigation lines, and AC condensation lines.
- Don’t overwater your lawn; pests love damp soil.
- Empty pet bowls overnight and clean up the water around the sinks.
Tidy the Kitchen & Pantry
- Keep dry goods in closed containers.
- Wipe down counters and sweep crumbs regularly.
- Take the trash out often and use tight-fitting lids.
Landscape Defensively
- Trim shrubs and trees that touch your house; pests use them as bridges.
- Avoid mulch; opt for gravel near foundations.
- Clear yard clutter and piles of leaves or debris.
Backyard Pest Control During Phoenix Summers
Your backyard can be an open invitation if not monitored closely. Here’s how to stop pests from taking over your outdoor space:
- Switch to yellow outdoor lighting to avoid attracting flying bugs.
- Keep pet food, birdseed, and compost bins sealed and stored away.
- Walk your yard weekly to check for ant hills, spider webs, or scorpion hiding spots (near rocks, cool corners, or wood piles).
- After storms or heavy watering, treat standing water with mosquito dunks.
Testimonial from a Local Resident:
“Last year, we kept finding scorpions in the backyard near our AC unit. I had no idea they were hiding out in the cool, damp gravel area. Our pest tech from Gilbert explained how the combo of heat and monsoon moisture makes certain spots perfect for them. Since we sealed around the unit and treated it after each storm, we haven’t seen any indoors. It was a total game-changer.”

Monsoon Season Pest Tips
Arizona’s monsoon storms (typically from late June through September) are known for stirring up all kinds of pests.
What to Do:
- Clean out gutters, drains, and puddles around your property.
- Schedule preventative pest treatments right before and after storms.
- Watch for termite swarms and roaches in damp areas.
- Be extra cautious of scorpions in August, when they’re most active.
Indoor Summer Pest Protection
Even if your home looks spotless, pests love cool, quiet areas. Focus your indoor protection on these high-risk zones:
- Garages and laundry rooms (especially near water lines)
- Kitchens and pantries (crumbs and spills = ant magnets)
- Behind appliances and inside cupboards
- Attics and closets (common for spiders and silverfish)
When to Call a Professional
DIY treatments can help, but sometimes, a full-blown infestation needs a professional touch.
Call a local pest expert if:
- You’ve seen multiple scorpions or roaches inside within a few days.
- Pest sightings continue even after sprays or traps.
- You find termite mud tubes, droppings, or unexplained wood damage.
- Rodents show up around trash bins or AC units.

Frequently Asked Questions
1. Why are there more pests in my home during summer in Arizona?
Phoenix summers are brutally hot, and pests don’t like it any more than we do. Bugs like scorpions, roaches, and ants head indoors looking for cooler temps, water, and food. Your air-conditioned home becomes a five-star resort for desert pests if you’re not sealing up entry points and treating them proactively.
2. When does summer pest activity usually start in Phoenix?
Pest activity can increase without you even noticing it during the beginning of May. Then, starts to surge between June and August. They can be triggered when the temperatures can hit 100s. On the other hand, some bugs only appear aggressive when monsoon ends. That is usually during late June.
3. What pests are most common during Phoenix summers?
The most frequent summer invaders include:
- Bark scorpions
- American and German cockroaches
- Mosquitoes
- Sugar and pavement ants
- House spiders and silverfish
They’re driven inside by heat, flooding, or the search for food and water.
4. Can I prevent scorpions from getting into my home during summer?
Yes. The first step is just giving pests fewer places to sneak in. Take a walk around your home and fill in any small cracks or gaps you see near windows, doors, or the foundation. Adding door sweeps can also block scorpions from slipping under entryways.
5. How does monsoon season affect pest activity in Arizona?
Monsoon storms have a great impact on the nesting sites of every pest. The increased level of humidity can trigger termite swarms, mosquito outbreaks, and roaches. Even when the storm is gone, they can still hide and stay inside the corner of your house.
6. What’s the best way to mosquito-proof my yard in summer?
The key is to eliminate standing water. Empty plant saucers, pet bowls, and clogged gutters. Use mosquito dunks in birdbaths or ponds, and switch to yellow outdoor lighting, which doesn’t attract bugs as much as white light.
7. Do store-bought sprays work in the desert heat?
They can help with light issues, but extreme heat and tough pests in Phoenix often require professional-grade solutions. Also, sprays break down faster in 110+ temps, so they may not last long enough to provide full protection during peak months.
8. Are desert pests dangerous to pets or children?
Yes. Bark scorpions, black widows, and even fire ants can be harmful to pets and small children. Symptoms from stings or bites may include swelling, vomiting, allergic reactions, or worse, so prevention is key in homes with little ones or animals.
9. How often should pest control be done in summer in Phoenix?
Monthly treatments are recommended during summer for most desert homes, especially those near natural washes, open land, or older neighborhoods with gaps and entry points. For many homeowners, bi-monthly visits work outside of peak summer.
10. Should I keep pest control going after summer ends?
Definitely, while summer is intense, fall and winter pests (like roof rats, spiders, and cockroaches) don’t stop showing up just because it’s cooler. In fact, many pests move indoors once summer ends. Keeping a year-round pest prevention plan is your best long-term defense.
