Below is what Ontario customers get when they book mice removal with us — local dispatch, and the exact process we use across California.
Roof rats establish in California neighborhoods by traveling along mature tree canopies, power lines, and dense landscaping that touches eaves. Once they reach attics or wall voids they build nests from insulation and chew wiring, creating fire hazards and spreading droppings that homeowners first notice as small dark pellets near baseboards or in kitchen cabinets. Field-edge rodents follow harvest cycles into Central Valley structures but similar pressure appears in Southern California when irrigation and fruit trees provide year-round food.
Homeowners typically see the first signs as gnawed food packages, scratching sounds at night, or dark smears along baseboards. These clues indicate an active runway rather than isolated intruders, yet many attempt to solve the problem with retail traps or poison placed only where droppings appear. Such methods fail because they leave entry points open and allow new rats to replace those removed.
