Catchmaster's Heavy Duty Rat, Mouse, Snake & Insect Glue Trays are made with AP&G’s legendary, non-toxic glue formula. They are sticky enough to catch all kinds of crawling insects, snakes, scorpions, spiders, mice, and rats, but not enough to cause a nuisance for you and/or your pets. Glue trays are a great option for locations that are damp and/or humid where glue boards and other traps may not hold up.
