Pests need water, food, and shelter to live, just like you. Explore what you can do to get rid of them and prevent them from invading your home. 

Reducing moisture prevents and reduces mold growth. Your first action is to address the source of the moisture, which causes mold. 


General information
Call the Anonyous Smoke-Free Hotline @ (650) 573-3777 to report drifting smoke.

Smoke-Free Housing

Drifting smoke in multi-unit housing (such as apartments and condos) is a danger to children and families. While the number of current smokers in our community continues to decrease, many residents are still exposed to secondhand smoke every day. This is why the San Mateo County Tobacco Education Coalition (TEC) educates tenants about what steps they can take if smoke is drifting into their unit. At the same time, TEC works with landlords to educate them about the benefits of developing smoke-free policies for the apartment or condo buildings they own.
