Possum Removal With One Way Doors

Hi, I'm Sean from Cannon Pest Management. You might often need Pest controllers saying how they use one way doors to remove possums so I'd thought I'd just quickly share you exactly what they are. We have two types, this one is use in tile roofs. We take tile from the roof and we place this door where the tile goes. This opening goes inside roof and this sitting on top of the roof. What happens is when the possum goes the roof it comes out pushes the flap and then the flap closes again and that means the possums can no longer return because they cannot re open the flap to enter the roof again.
