Rat Poison and traps are the most common method of dealing with rodents. This is understandable as rats can cause severe damage to a property. However regardless of how efficient these methods may be, the fact remains you already have a rodent problem by the time you look to use these.

The only viable method of ensuring 100% protection from potential damage is to stop rats before they can access your property. 

We offer a solution that is an alternative to rat poisons and traps. Our Rat Flaps is an affordable solution to the problem of rodents entering properties through drainage pipes and ducts.
