Why Rats Infest Properties

Rats are incredibly resourceful creatures that actively seek out food, water, and shelter to survive.

Identifying and eliminating these attractants is the first crucial step to getting rid of rats in the walls.

Food Sources

Leftover food, garbage, and pet food left out in the open can serve as a magnet for rats, drawing them into your home in search of an easy meal. 

To prevent attracting these pests, ensure all food waste is correctly disposed of in sealed containers and that pet food is stored securely when not in use.


Rats are constantly on the lookout for cozy nooks and crannies where they can nest and reproduce safely, away from predators and disturbances. 

These hidden spaces within walls, attics, and basements give the perfect environment for rats to thrive, making it vital to seal any potential entry points and keep these areas clutter-free.
