We have a rat living under our duck house, we will have babies in about a week. We have tried to deter it as much as possible, cleaning out the nest, spraying with the hose etc. but it is under the dog (duck) house in the duck coop only about 3 inches off the ground. The ducks cannot get under it but i am worried about putting poison under it incase he pulls it out where the ducks could get to it. There isn't enough clearance for a snap trap. I need to get rid of him before we have babies!!! He hasn't bothered the ducks but has free access to their food :-(
