Identify house and deer mice, seal the dime-sized gaps they slip through, and control them with exclusion, sanitation, and trapping.
Call (619) 421 - 2101Mice can pose real health and safety risks for families and businesses, and they multiply fast. This Integrated Pest Management (IPM) plan combines prevention, ongoing monitoring, and trapping to achieve long-term, sustainable mouse control — prioritizing non-chemical methods and using rodenticide only as a carefully managed last resort.
The two things that decide whether mice move in are access and food. Close the gaps, remove the food, and the rest of the plan has something to build on.

Call (619) 421 - 2101 →Two species turn up locally — one urban, one rural, and one of them a health concern.
The mouse you will find in San Diego homes and businesses. It thrives on our food and waste and slips through astonishingly small gaps.
More common on the rural outskirts of the county. Important to recognize because it can carry hantavirus, so its droppings must be handled with care.
Mice have adapted almost perfectly to city life, thriving on overflowing trash, dropped crumbs, and improperly stored food. A small gap plus an easy meal is all it takes for them to move in and start breeding. Sanitation and exclusion work because they remove both halves of that equation.
How GC Termite Control manages mice — from exclusion and trapping to a judicious chemical last resort.
Regular inspection catches mice early — when they are far easier to control.
Exclusion and sanitation take away the two things mice need: a way in and a meal.
Small changes to habits and the yard make a property far less hospitable to mice.
Outdoors, natural predators help keep mouse numbers down.
Trapping and barriers clear mice safely, without poisons in the home.
If rodenticide becomes necessary, professional handling keeps people, pets, and wildlife safe.
Close the gaps and cut the food supply mice rely on.
Seal gaps and cracks with steel wool, copper mesh, or caulk
Add door sweeps and fresh weatherstripping to exterior doors
Store food, pet food, and bird seed in airtight containers
Wipe up spills and take out trash promptly
Remove clutter and cardboard that mice nest in
Cover vents and openings with quarter-inch hardware cloth
Keep grass trimmed and wood off the structure
Set snap traps along walls where you see droppings
GC Termite Control will find the entry points, seal them, and trap the mice already inside — an integrated plan that ends the problem instead of masking it.
About a quarter inch — roughly the size of a dime. A mouse can flatten itself to squeeze through gaps that look far too small, which is why sealing every little opening with steel wool or copper mesh is the core of effective mouse control.
Look for droppings, gnaw marks on food packaging and wood, greasy rub marks along baseboards, shredded nesting material, and scratching or scurrying sounds inside walls and ceilings at night. A musty odor can also point to an active infestation.
They can be. Mice spread illnesses including hantavirus (from the deer mouse), salmonellosis, and leptospirosis through their droppings and urine. Never dry-sweep or vacuum droppings — dampen them first, disinfect, and wear gloves. The San Diego County Vector Control Program and CDC both publish safe cleanup guidance.
Very likely. Mice breed quickly, so a single mouse usually signals more nearby. It is far easier and cheaper to stop them early than to clear an established population, so it is worth acting the moment you see the first signs.
