Glue traps are widely considered one of the most inhumane methods of rodent control available. Unlike devices designed to kill quickly, glue traps work by immobilizing an animal on a sticky adhesive surface, where it remains conscious and struggling until it eventually dies of dehydration, starvation, suffocation, or exhaustion. That process can take anywhere from several hours to five days.
How Animals Die on Glue Traps
A glue trap doesn’t kill anything. It holds an animal in place by bonding its fur, skin, or feathers to a layer of industrial adhesive. Once stuck, the animal panics. In its desperate attempts to break free, a mouse or rat will tear patches of skin and fur from its own body, fracture its own limbs, and in some cases chew off its own legs. Animals that press their faces into the glue while struggling can suffocate over the course of hours.
For those that don’t suffocate, the death is slower. Completely unable to reach food or water, immobilized animals die of dehydration and starvation over a period of days. Exhaustion and shock from their injuries compound the process. The trap doesn’t deliver any kind of blow or lethal mechanism. It simply holds the animal in place while its body shuts down, which is the core reason animal welfare organizations classify glue traps as inhumane.
Non-Target Animals Get Caught Too
Glue traps are indiscriminate. They catch whatever touches them. Wildlife rehabilitators regularly treat birds, lizards, snakes, and even small pets that wandered onto a glue board. A case documented by the Conservancy of Southwest Florida involved a burrowing owl found stuck to a glue trap on Marco Island. The owl was significantly underweight, suggesting it had been trapped for several days. It had increased respiratory effort and damaged feathers across its wings and tail from struggling against the adhesive.
Birds are especially vulnerable because their feathers bond easily to the glue, and the damage to flight feathers can be permanent. Reptiles, chipmunks, and juvenile animals of many species are also common victims. If you place a glue trap outdoors or in a garage, the odds of catching something other than a mouse or rat increase substantially.
Growing Legal Bans
Several governments have concluded that glue traps cause enough suffering to justify banning them outright. Scotland’s ban took full effect on July 1, 2026, under the Wildlife Management and Muirburn Act. Using, possessing, or selling a glue trap there is now a criminal offense carrying fines up to £40,000 or up to 12 months in prison. The ban covers all vertebrate animals.
In the United States, West Hollywood became the first city in the country to ban glue traps, a move that inspired federal legislation introduced by Congressman Ted Lieu to prohibit their use more broadly. England has also restricted glue trap use to licensed pest controllers operating under specific conditions, effectively ending casual consumer use. These legal actions reflect a growing consensus among lawmakers and animal welfare experts that the suffering caused by glue traps is disproportionate to their pest control benefits.
What to Do if an Animal Is Stuck
If you find an animal on a glue trap, you can free it using cooking oil. Warm a bottle of rapeseed, vegetable, or canola oil under hot water until it feels warm on your wrist but not hot enough to burn. Put on thick gloves and gently restrain the animal near its head with a towel, keeping the towel close but not covering its face. Massage the warm oil into the fur, feathers, or skin where it meets the adhesive. This takes several minutes of patient work as the oil gradually softens the glue.
Once free, place the animal in a secure container with air holes and take it to a wildlife rehabilitator or veterinarian. Oil on fur or feathers interferes with an animal’s ability to regulate body temperature, so even a freed animal needs professional care. If no facility is nearby, keep the animal in a warm, dark, quiet location and resist the urge to check on it repeatedly. Recovering animals need calm.
More Humane Alternatives
The most effective approach to rodent problems is prevention: sealing entry points, removing food sources, and eliminating nesting opportunities. Mice can fit through gaps the width of a pencil, so steel wool and caulk in cracks around pipes, vents, and foundations go a long way.
When lethal control is necessary, well-designed snap traps are considered far more humane than glue boards. The key is spring strength. A trap with a powerful snap kills quickly, while a weak trap may injure without killing, leaving the animal to suffer a slow death similar to what happens on a glue board. For outdoor use, snap traps should be placed inside locked bait stations with small entrance holes sized only for mice and rats, which prevents pets and non-target wildlife from accessing them.
Live-catch traps are another option, though they require checking every few hours. A mouse left in a live trap overnight can die of stress or dehydration, defeating the purpose. If you use one, check it at least twice daily and release the animal at least a mile from your home to reduce the chance it returns.
