Roof Rats

Roof rats are agile climbers that prefer elevated nesting areas like attics, soffits, and roof returns. They often enter through vents, gaps in eaves, or where utility lines meet the structure. Once inside, they build nests in insulation and chew electrical wiring, posing fire hazards. Roof rats typically leave greasy rub marks along travel paths and are most active at night.

House Mice & Field Mice

These tiny invaders can fit through openings as small as ¼ inch — around door frames, siding joints, or gaps in weatherstripping. Mice reproduce faster than any rodent species, turning a minor sighting into a major infestation within weeks. They contaminate food, produce allergens, and follow pheromone trails that lead future generations back into unsealed homes.

Norway Rats

Norway rats are the heavy-set, burrowing species often found entering around foundations, garage corners, A/C line penetrations, and drain areas. They dig tunnels under patios, slabs, and landscaping, creating structural voids that can lead to erosion or slab cracking. Indoors, they gnaw wood framing, baseboards, and storage areas. They prefer to stay low but can invade walls and crawlspaces quickly once a scent trail forms.

Squirrels 

Although technically wildlife, squirrels behave much like rodents once inside. They enter through roof returns, soffit gaps, and attic vents — often chewing open their own entry points. Inside, they shred insulation for nesting, chew wiring, and cause early-morning scratching noises. Squirrel droppings and shredded insulation trails are common attic indicators. Like rats, they return year after year unless exclusion is completed properly.
