Rat problems often stem from drains, using them to gain access to commercial buildings and domestic homes. Due to this, proofing with a rat drain blocker is an essential step to get rid of a rat infestation. Check out our range of innovative drain protection products, including popular brands such as Nordisk, Rotech, and Ratwall. Installation requires a 1m extension pole which you can add to your basket on the rat flap product page. Shop other professional rat poisons and rodent proofing materials.
