Rat Control and Extermination

The Norwegian rat, also known as the brown rat, common rat, sewer rat, or wharf rat first came to America onboard Colonial sailing vessels. Norwegian rats now occupy every major city in the US and Canada. During fall they begin to reproduce and at the same time they start coming indoors. A single female brown rat can give birth to more than forty young in one year. The rats enter through holes they either find or create.

When treating for rats it all begins with exclusion. We will treat any rat holes with tracking powder and set bait boxes. Under certain conditions we will attempt to live trap the rats. Live trapping can catch rats in one night and you don't have to worry about them dying behind walls. Nothing smells worst then a dead rat! The disadvantage to rat trapping is you seldom catch them all, so combining exclusion with rodenticides is necessary.
