Place baitboxes inside the perimeter at 10ft spacing, check every week and replenish as necessary, keep baiting until no more bait is taken then check every month.

Don’t touch the boxes unless you need to replenish

Check by using a camera phone looking inside the entrance.

Nail three plastic rat traps to a floorboard and place against the wall bait with chocolate covered raisins cover the traps with an upturned bread crate, cabbage crate or storage box to ensure other animals cannot access the traps
