Size the board
Best rodent glue boards
The best glue board is the one that matches the rodent and the gap. A mouse board under a stove tells you the kitchen runway is live. A rat-size tray is for a floor commute you can check. Neither board replaces snap traps or a sealed hole, and both are a problem if a pet can reach them.

Which one to buy
Hardware
Catchmaster mouse and insect glue traps
Best for mice — Pre-baited mouse boards. Too small for a rat, which walks off or drags the board. Use along the wall.
Hardware
Catchmaster 48R rat-size glue boards (2-pack)
Best for rats — Catchmaster-style rat trays. Useless in a shallow cabinet a rat will not enter, and a poor attic tool for roof rats on a beam.
Hardware
Catchmaster 72MAX glue boards
Best low-profile monitor — Flat enough for a kick space. It catches insects too. Replace it when dust coats the glue.
Pick the board from the dropping
Mouse droppings are rice-sized. Norway rat droppings are blunt capsules about three-quarters of an inch. If you put mouse glue on a rat runway, you will find a dragged board and decide glue “does not work.” Match the board, then still buy the snap trap that finishes the job. Details are on Best mouse traps and Best rat traps.
Common questions
What is the best glue trap for rats and mice together?
There is not one. Use a rat tray where the droppings are capsules and a mouse board where they are rice-sized. Many buildings have only one of the two.
How often should I replace a glue board?
When it has a catch, when it is dusty, or when it has sat long enough to dry. An untouched dusty board is not monitoring anything.
Are scented glue boards better?
Scent is secondary. The path and a clean adhesive surface decide the catch. A scented board in the wrong room stays empty.
