Do you have a problem with rats at your property?
If you are having problems with rats, then your drains are one of the most common ways for rats to access your property.
A rat blocker is the simplest, most effective way to prevent rodents entering your home from the sewer.
It is all so simple. The rat blocker (or rodent valve) is installed in the line from the public sewer to your property.
The rat can leave your property through the rat blocker, but the serrated flaps mean he can never return.
