Rats can be a problem for residents, property owners, businesses and entire neighborhoods. Their gnawing and burrowing can cause damage and they can contaminate food, spread disease and reduce our quality of life.
Rats seek out places to live that provide them with everything they need to survive: food, water, shelter and safe ways for them to get around. To keep rats out of your property or neighborhood, you and your neighbors can take steps to make life more difficult for rats:
- Clean up. Garbage and clutter give rats a place to hide.
- Rats eat your garbage, so store all garbage in hard plastic rat-resistant containers with tight fitting lids. Provide enough trash containers for all of the occupants of your property. Any exposed garbage will attract rats.
- Keep landscaped areas around your property free of tall weeds and trim shrubs that are close to the ground.
- Check for cracks or holes in the foundation of your building, sidewalk and under doors and repair them by filling and sealing them.
- On the street or in a park, put your litter in a can and do not feed birds or other wildlife.
