Rodent ControlScratching in the attic after dark is almost always roof rats, not mice. Peterson Pest Management finds how they are getting in, removes them, and closes the entry points so they stay out.
If you are hearing movement above the ceiling after dark, the East Valley's most common answer is roof rats, not house mice. Roof rats travel power lines, fence tops and palm fronds, den in citrus canopies, and get into an attic through a roofline gap, a torn vent screen or a gap where a utility line enters the house. A Peterson inspection starts by finding that entry point, not just chasing the noise.
Established neighborhoods with mature citrus trees and tall palms give roof rats everything they need: continuous canopy cover to travel under, fruit to eat, and homes built before modern vent screening was standard equipment. If your block has citrus in the yards and palms along the street, roof rat activity is common, and it tends to move house to house along the same tree lines.
In the newer subdivisions of Queen Creek, San Tan Valley and the desert-edge parts of Mesa and Phoenix, the more likely culprit is a pack rat, also called a woodrat. Pack rats build stick nests in block wall voids, sheds, stacked patio furniture, and the engine bay of a vehicle that sits for a few days. A pile of sticks and debris tucked against a wall or under a shed is usually the giveaway.
Mice show up in homes of every age and every neighborhood. They get in through gaps as small as a pencil around plumbing penetrations, garage door seals and foundation vents, and once inside they nest close to a food source rather than living in the attic. Droppings the size of a grain of rice along a baseboard or under the sink point to mice rather than rats.
A rodent call starts with an inspection of the attic, roofline, foundation and yard to identify which rodent is present and how it is getting in. From there, service covers a trapping and removal program sized to the activity level, identification of the entry points that need to be closed, and sanitation advice for anything drawing rodents to the property, such as fallen citrus or pet food left outside overnight.
Bait dropped around a yard or attic with nothing else changed often sends a rodent to die inside a wall void where nobody can reach it, and it puts curious dogs and cats at real risk. Peterson pairs any bait use with trapping and exclusion work, so the goal is removal and a sealed structure, not bait sitting out indefinitely.
Trapping clears out the rodents that are already inside. Exclusion, closing the roofline gaps, replacing torn vent screens, and sealing plumbing and utility penetrations, is what keeps the next one from moving in behind them. Our technicians walk the property with you and point out exactly where the openings are before any work starts, so you know what is being closed and why.
Roof rats favor established neighborhoods with mature citrus and palms, pack rats favor the desert edge, and house mice turn up everywhere in between. Gilbert, Mesa, Chandler, Queen Creek and Phoenix all get rodent calls.

Noise overhead after dark is almost always roof rats moving along the roofline or in the attic space itself. Daytime activity is less common. The sooner the entry point is found, the fewer rodents move in behind the first ones.
Droppings the size of a grain of rice usually mean mice, while droppings closer to the size of a raisin point to rats. Rats also tend to stay in the attic or wall voids, while mice nest close to a food source, often in a kitchen or garage.
Citrus and palms raise the odds of roof rats, but any yard with a block wall, a shed, standing water from irrigation, or pet food left out overnight can support rodent activity. Pack rats and mice do not need citrus at all.
It depends on how established the activity is and how many entry points there are. Our technicians lay out what to expect for the property after the inspection rather than quoting a generic timeline.
Exclusion is sealing the gaps rodents use to get in, roofline vents, plumbing penetrations, foundation gaps and door sweeps. Trapping removes the rodents that are inside; exclusion is what keeps the next ones out.
Bait is used carefully and only as part of a full removal and exclusion plan, never as the only step, because bait alone near pets is a real risk and does nothing to close the entry point. Our technicians explain what is used and where before any work starts.
