Tempe's reputation for dry heat does not stop roaches. They are drawn to the water in irrigated yards, to the food in apartment kitchens and to the cool shade of block walls and sewer lines. The species mix in Arizona is different from the Southeast, so identification matters. Call (844) 725-1661 to be connected with an independent, licensed provider.

Roaches you will find in the Valley
- Turkestan cockroaches: a species well established across Arizona. Males are tan and winged; females are dark and wingless. They live in yards, under pavers, and in meter boxes, and are attracted to lights and water.
- American cockroaches: large, reddish brown, coming from sewers and storm drains, particularly after monsoon storms.
- German cockroaches: small indoor roaches, typical in apartments, restaurants and rentals around ASU.
- Bark roaches and wood roaches: sometimes enter from landscaping, particularly near palm trees and wood piles.
Why roaches thrive in a desert city
Roaches die quickly without moisture, so they go where it is. In Tempe that is irrigation boxes, sprinkler valves, pool equipment pads, pet water bowls and the damp spaces under sinks. The monsoon season sends outdoor roaches searching for dry shelter, so you see more of them indoors in July and August. In apartment complexes, German roaches ride along in grocery bags and secondhand appliances, then spread through shared walls, pipes and trash rooms.
What providers do about them
- Species identification: sticky traps and a close look at size and markings determine strategy.
- Gel bait: placed in cracks and hinges for German roaches, where it is eaten and passed to others in the colony.
- Growth regulators: to disrupt reproduction.
- Exterior barrier: treating the foundation, block walls, meter boxes and drain edges for Turkestan and American roaches.
- Sanitation and sealing: advice on moisture, cleaning and gaps around plumbing.
Over-the-counter sprays can make roaches avoid treated areas and spread, so bait-based strategies tend to work better.
Tempe-specific tips
- Check and fix leaking irrigation components next to the house.
- Keep pool equipment areas and meter boxes clear of debris.
- Shut the garage door at dusk when roaches are active.
- Rinse recycling and keep outdoor bins away from the door.
- In apartments, tell the manager promptly so neighboring units can be inspected.
Tenants and landlords
Tempe has a large rental population. If roaches are in a rental, notify the landlord in writing and keep a record. German roach problems tend to return unless the entire building is treated, so cooperation between neighbors matters. For owners, regular preventive service helps keep tenant turnover from spreading infestations from unit to unit.
Kitchens and bathrooms first
Inside a Tempe home, roaches concentrate where water and food overlap: under the kitchen sink, behind the dishwasher, around the refrigerator motor and in bathroom vanities. Pull out the contents of these cabinets before the technician arrives so that bait and dust can reach the cracks. Fixing a slow drip or a loose supply line often does more good than another can of spray, because roaches need that moisture to survive Arizona's dry air.
Cockroach questions from Tempe residents
Are Turkestan roaches dangerous?
They are mostly a nuisance and outdoor pest, though they can contaminate surfaces if they get inside.
Why do I see roaches after storms?
Heavy rain floods sewers and burrows, and roaches move to dry shelter, including your home.
Will cleaning alone solve it?
Cleaning helps but rarely finishes the job once an infestation is established.
How many visits are typical?
German roaches often take more than one visit. Your provider can map out a plan.
