Mouse sticky traps are commonly used and are also called glue boards. They are easy to set and use, inexpensive and work well. Whether on a board or in a shallow tray, the glue immobilises a mouse. It is super sticky and does not harden. Once a mouse touches the glue, it is trapped. The glue sticks to fur and its feet sink in.
Peel off the top film carefully and place the glue trap in a spot that the mouse is sure to go over or through. Droppings will give you an idea of the mouse's normal routes. Try to block off the area so that the mouse has to go over to the trap. Any obstacle will help narrow its path. Pick a location where the trap will not be disturbed.
Add the bait. A small piece of cheese works fine. If the glue trap is scented, you may not need bait. The mouse will be attracted by the scent of the trap.
If a mouse is caught alive, it can be a shock. The animal is suffering and it is best to put it out of its misery as soon as possible. Ask someone for help if you are unsure about this.
Remove the trap with the mouse carcase. Use latex gloves and put the mouse and trap into a sealed plastic bag. Toss the bag and trap into the trash. If there are multiple mice to be caught, uses multiple traps in varied locations.
Try using a few different types of bait including cereal and bread. Mice do not eat meat. Touch the trap only on the sides of the tray.
The dead mouse will start to smell if left to decompose and die. The mouse may not be dead, so be careful and avoid bites. It may be shocking to see an animal suffering. Also, be prepared to have to put the animal out of its misery. The scented glue many trap other animals including cats, bats, squirrels, rats, snakes, other rodents and birds. Do not use if there are children in the home. See resources for more humane ways of trapping mice.
