Why Even One or Two Mice Can Be a Red Flag
Mice prefer living in groups, so seeing one mouse may indicate others are hiding nearby. Females can start reproducing as early as six weeks old, producing multiple litters each year. In San Diego’s mild climate, these rodents can stay active year-round, meaning small problems can escalate quickly if left untreated.
Signs of a Potential Mouse Infestation
You might not always see mice, but they leave plenty of clues. Look for small, dark droppings in cupboards, drawers, or along baseboards. Check for gnaw marks on wires, furniture, or even food packaging. Mice also build nests from shredded paper, fabric, or insulation, often tucked away in attics, basements, or garages. You may hear scratching, squeaking, or scurrying at night as mice are most active when it’s quiet. And if you notice a strong, musky odor in certain areas, that’s often a sign of urine from a nearby nest.t, when mice are most active.
Risks of Ignoring Mice
Mice may seem harmless, but they can pose real threats:
- Property damage: Chewing wires, insulation, and structural materials
- Food contamination: They often carry bacteria that can contaminate surfaces and food
- Health hazards: Mouse droppings and urine can trigger allergies and spread diseases
Even a small number of mice can multiply rapidly, turning a minor nuisance into a costly problem for San Diego homeowners.
How Mice Get Inside Your San Diego Home
Mice can squeeze through holes as small as a dime. Common entry points include:
- Cracks in foundations or walls
- Gaps around doors and windows
- Spaces around pipes, vents, and utility lines
- Unsealed attics, basements, and garages
Sealing these areas is crucial to preventing infestations.
Preventing and Managing Mouse Infestations
Homeowners can reduce the risk of mice by:
- Sealing cracks and gaps around your home’s exterior
- Storing food in airtight containers
- Keeping your home clean and clutter-free
- Removing piles of wood, cardboard, or debris near the house
- Monitoring for early signs of mouse activity
While these steps are helpful, professional pest control offers the most reliable protection.
