Arizona has a serious rodent problem. Roof rats arrived in the Phoenix metro decades ago and have spread throughout Maricopa and Pinal counties, nesting in attics, block walls, palm trees, and citrus groves. Pack rats — also called woodrats — are native to the Sonoran Desert and build massive stick nests in and around desert landscaping. Both species breed year-round in Arizona's mild climate, and a small infestation can become a major structural and health hazard within weeks. Rodent droppings contaminate food and surfaces, gnawed wiring causes house fires, and rodents carry diseases including hantavirus and leptospirosis. Getting ahead of an infestation fast matters — and that means using a bait that actually works.

Why Pest Control Pros Use Bromethalin Bait
Top Gun All-Weather Bait Blocks by Bell Labs use bromethalin, a neurotoxin that kills rodents after a single feeding. Unlike first-generation anticoagulants (warfarin, diphacinone) that require rodents to feed multiple times over several days, bromethalin disrupts the central nervous system after one dose — making it significantly more effective against bait-shy rats that have learned to avoid poison stations. The all-weather paraffin wax formula holds up in Arizona's extreme heat and monsoon humidity without crumbling, melting, or losing potency. Each 4 lb pail contains 64 one-ounce blocks — enough to stock multiple bait stations around your property for months. The blocks are designed to thread onto the center rod of standard tamper-resistant bait stations, keeping them secure and inaccessible to children and non-target animals.

How to Place Bait Stations in Arizona Homes
Place bait stations along rodent runways — the paths rats travel repeatedly between their nest and food sources. Look for grease marks along walls, droppings concentrated in corners, and gnaw marks on wood or wiring. Common placement locations in Arizona homes include along the exterior foundation, inside the garage near the walls, in the attic near entry points, and along block walls where roof rats travel. Use one station every 15–30 feet along active runways. Check stations every 3–5 days initially and replenish bait as needed. Once activity drops off, check weekly. Always use tamper-resistant stations when placing bait anywhere children or pets could access the area — bromethalin is toxic to dogs and cats if ingested.
Safety First — Always Use Tamper-Resistant Stations
- Never place loose bait blocks without a locked bait station housing
- Keep stations out of reach of children, dogs, and cats — bromethalin is toxic to pets
- Wear gloves when handling bait blocks to avoid transferring human scent
- Dispose of dead rodents in sealed bags — do not leave carcasses where pets can find them
- Store unused bait in the original sealed pail in a cool, dry location
- Check stations every 3–5 days and replenish bait until activity stops

Rodent Problem Getting Out of Hand?
Bait blocks work well for light infestations, but if rodents are active throughout your home, in the attic, or inside walls, you need a professional inspection. Pest Control Bros will identify entry points, seal them, and set up a bait program — free inspection, no contracts.
