Vineyards, orchards, and creek corridors make Sonoma County a rodent haven. Roof rats travel along grapevine trellises into attics. House mice exploit gaps in aging foundations. Voles tunnel through landscaped gardens and vineyard rows. Each requires a distinct control strategy.
Call (707) 286-7002Sonoma County's agricultural landscape supports dense rodent populations year-round. Vineyards provide food and cover. Creek systems like Santa Rosa Creek and Mark West Creek act as wildlife corridors, channeling rodents directly into residential neighborhoods. After harvest season, rodents that fed on grapes and fallen fruit shift to residential structures for food and shelter.
The dominant rat species in Sonoma County. Excellent climbers—they travel along power lines, fence tops, and vine trellises to access rooflines. Common in attics, between floors, and in detached garages.
House mice enter through gaps as small as a dime. They nest in wall voids, storage areas, and appliance compartments. Voles (meadow mice) stay outdoors but cause extensive damage to lawns, garden beds, and vineyard drip irrigation lines by gnawing through tubing.
We inspect rooflines, foundation vents, utility penetrations, garage door seals, and where pipes or wires enter the structure. Roof rats in Santa Rosa commonly enter through gaps where Spanish tile roofs meet fascia boards—a construction detail prevalent in the area.
We deploy snap traps and multi-catch devices in identified travel routes. For roof rats, this means attic runways along rafters. For mice, behind appliances and along wall-floor junctions. Trapping allows us to confirm species, measure activity, and remove rodents without secondary poisoning risks to pets or wildlife.
After active populations are removed, we seal entry points with hardware cloth, copper mesh, metal flashing, and sealant. This is the most critical step—without exclusion, new rodents from surrounding agricultural land recolonize within weeks.
For vineyard and orchard properties, rodent control extends beyond the home. Voles damage root systems and irrigation. Gophers (a related issue) collapse vineyard rows. Roof rats nest in equipment barns and processing buildings.
We serve residential, commercial, and agricultural properties throughout:
After grape harvest (September–October), the food supply in vineyards drops sharply. Rats that spent summer feeding on fruit shift to residential structures for food and warmth. This seasonal migration is predictable—fall is the ideal time for exclusion work before the migration begins.
Yes. Rodent droppings and urine can carry hantavirus (primarily from deer mice), leptospirosis, and salmonella. Don't vacuum or sweep droppings—this aerosolizes particles. Dampen with a bleach solution first. For heavy accumulations, professional attic cleanup with HEPA filtration is recommended.
We generally recommend trapping for residential settings. Rodenticide baits carry secondary poisoning risks—a poisoned rat consumed by an owl, hawk, or neighborhood cat transfers the toxin up the food chain. Sonoma County has active raptor populations that provide natural rodent control; protecting them is both ecological and practical.
Yes. Voles create surface runway systems and burrow networks that damage root systems, bulbs, and irrigation lines. We use targeted baiting within burrow systems and habitat modification to reduce populations. For vineyards, we coordinate with your management team on timing around spray schedules.
Droppings are the easiest indicator. Rat droppings are ½ inch with pointed ends. Mouse droppings are ¼ inch, like dark rice grains. Rats need a half-inch gap to enter; mice need only a quarter inch. If you hear heavy thumping in the attic, it's likely rats. Light scratching or scurrying in walls is usually mice.
