There are a number of products designed to help catch rats, mice and other rodents. One of those is a rodent glue substance widely available in DIY centres. The material is applied to a piece of cardboard, baited and then placed in an area where rodents are present. Once the critter is stuck on the trap, the cardboard and the rodent can be discarded. It is recommended that a new trap be placed in the same place until you do not catch anymore for a few weeks.
Purchase a container of rodent glue trap at a local DIY supplier or pest control retailer.
Cut cardboard into 12.5 cm x 17.5 cm (5 inch x 7 inch) pieces. Wet your hands and add a little washing up liquid to make your hands slightly soapy. This will keep any excess glue from sticking to your hands.
Dip the lolly stick or tongue depressor stick in the glue and spread it on the cardboard to a thickness of no more than 6 mm (1/4 inch).
Place common household food in the middle of the glue boards. This can be as simple as breadcrumbs or pieces of cereal.
Position the glue boards in areas where rodents move in search of food. Secure the glue boards by placing a brick on a corner.
Block any known passageways in the area to guide the rodent over the glue board. Remove all rings or bracelets before beginning this task.
