Pest- and Mold-Free Homes
Three Steps to a Healthy Home
Pests need water, food, and shelter to live, just like you. Here’s what you and your landlord can do to get rid of them and prevent them from invading your home.
1. Inside your home: take away pests’ food, water, and shelter
- Clean grease, crumbs, and spills and don’t leave dishes in the sink overnight.
- Store food in sealed containers. Pests can chew through paper, cardboard and thin plastic.
- Remove clutter from floors, and store extra clothing in sealed plastic bins.
- Take out garbage frequently; rinse food containers before recycling.
- At night, put away or put a lid on your pet’s food and water.
- Avoid sprays, foggers or bombs; they don’t reach hiding places and push pests into walls. Sprays, foggers, or bombs must be disposed of as household hazardous waste.
- Keep your home clean using less-toxic products. Read More
2. Reduce moisture to prevent mold and pests
- Open curtains and windows and use ventilation fans when cooking and bathing.
- Fan should be free of grease, and reported to landlord if broken.
- Separate furniture and appliances, including refrigerator, from walls.
- Dry moisture from windows and walls after bathing.
- Report drips or leaks for repair to property management or the landlord.
3. In and around your home: ask your landlord to seal out pests
- Install door sweeps or other barriers.
- Screen all vents, windows and entryways and repair broken screens.
- Seal all cracks, crevices and holes in walls and ceiling.
- Repair drips and leaks; seal cracks and holes around pipes and electrical outlets.
- Keep carports and garages free of clutter. Safely get rid of unwanted and leftover chemicals for free through San Mateo County’s Household Hazardous Waste Program.
- Thin out dense trees and overgrown plants. Trim branches and leaves that come close to gutters and roofs.
- Maintain interior and exterior water, drainage (incl. gutters), and sewage systems.
- Rinse common garbage and recycling bins as needed to keep them grime-free.
- Rinse common garbage and recycling bins frequently.
