Chew cards are a great way to work out the best location for your backyard trap. This is especially helpful when you first start out trapping or if your trap hasn’t caught anything for a while.
Installing chew cards
Start by placing the cards in areas where you suspect rat activity, eg. near compost or rubbish bins. Nailing it to a nearby tree or fence (at a height of 50mm-100mm) will help keep it secure. We suggest leaving it out for around 5-7 nights.
