When the Phoenix monsoon season hits between July and September, moisture in the air from months of desert heat sends crickets scurrying for shelter, and your house may as well be a five-star hotel. Some homeowners talk about window screens and foundation cracks, but leave door gaps as the most ignored means of entry, as crickets are entering through to gain access.
If you have been hearing that telltale chirping emanating from somewhere near your baseboards, it could be traced back to your doors. Connecting with greenmangopest.com early in the season can help you seal every entry point before the infestation takes hold.
Why Phoenix Homes Are Especially Vulnerable to Cricket Intrusion
With an average of 299 days of sun per year, and summer temperatures routinely exceeding 110°F, there is serious desiccation stress that drives crickets such as Acheta domesticus (house cricket) and Gryllus species into the cooler dark. Your home is exactly that. But in addition to the heat, Maricopa County’s fast-moving suburban development has pushed families further into desert areas, building homes directly on cricket territory. Now add some monsoon moisture, and the cricketers arrive!

The vast majority of homes in the area also come with shabby or poorly fitting door frames, a product of Ed’s old stomping grounds, Maricopa County, being one of America’s fastest-growing housing markets over the past two decades.
How Door Gaps Let Crickets In: What’s Actually Happening
Crickets do not take up much space; a mere 1/4-inch gap is all they need to slip right through. Common Door Gap Problems in Homes in Phoenix
- Bottom door sweep gaps – especially in older Phoenix and Scottsdale builds
- Threshold wear on sliding patio doors – particularly heavy usage wears these parts out more quickly than you may think
- Side weatherstripping deterioration – extreme sunny conditions in Phoenix lead to materials breaking down quickly
- Garage door bottom seal gaps – one of the most common missed entry points
- Gaps around door frames from soil shifting – soils in Maricopa County, mainly clay, expand and shrink with the seasons, which slowly warp frames.
How to Identify and Fix Door Gaps in Your Phoenix Home
1. The Dollar Bill Test: A Quick DIY Gap Check
Shut your door and slide a dollar bill along the bottom and sides. If it slips through like butter, you have created a gap through which even crickets can pass. It’s a two-minute check, free of charge, and shows exactly what you need to repair.
2. Replacing Door Sweeps: The Most Effective First Fix
Standard vinyl door sweeps will not last long in Phoenix with its heat and direct sunlight; they crack and compress sooner than you would think. Buy aluminum or reinforced rubber sweeps instead. Brush-style sweeps provide a better seal without creating friction and are the best option for sliding glass doors, which are often used in Arizona homes.
3. Weatherstripping for Phoenix’s Heat: What to Use
Foam tape weatherstripping can be a simple fix, but it will deteriorate in 110°F+ heat breaks down. EPDM rubber or silicone-based high-heat rated weatherstripping is the way to go for Phoenix homes. This is no mere preference; it is a need due to the climate here.
4. Garage Doors: The Overlooked Entry Point
Garage Doors are one of the most used access points in suburban homes; garage doors never see any pest-proofing. Heavy-duty astragal seals along the bottom edge do wonders. If you have a detached garage (a common feature of Phoenix-area properties), make sure to check it separately; it is often completely overlooked.

When Door Fixes Are Not Enough: Dealing with an Active Cricket Problem in Phoenix
Locking your doors is a good first step, but it is preventative, not curative. If the crickets are already in your home or nesting close to your house, merely sealing gaps will not solve the problem. Arizona-based pest industry data indicate that activity goes up over 40% when the monsoons hit, and this type of seasonal stress can easily overwhelm even good DIY practices. Local experts that cater to homeowners who face cricket infestations yearly alongside the arrival of monsoon season (like Saela Pest Control in Phoenix, who are aware of the patterns seasonality has on these problems).
