Glue traps are not an effective way to catch or control squirrels. These traps are designed for insects and mice, and when a squirrel encounters one, the result is prolonged suffering for the animal without solving your pest problem. Squirrels are too large and strong to be reliably held by adhesive boards, and in many cases, the animals caught are juveniles or non-target species like birds and chipmunks rather than the adult squirrels causing damage.
Why Glue Traps Fail for Squirrels
Adult squirrels have the body weight and muscle strength to pull themselves partially free from glue boards, often dragging the trap with them or tearing it apart. What you’re left with is an injured, panicked animal loose in your attic or yard rather than a captured pest. The traps were never engineered for animals of this size.
When smaller or younger squirrels do get stuck, the outcome is grim. Wildlife rehabilitation centers regularly receive juvenile squirrels pulled from glue traps with dislocated joints, broken legs, torn skin, and patches of fur ripped away. In one case documented by the Atlantic Veterinary College Wildlife Service, three six-week-old red squirrels were found stuck to a single glue trap, coated in adhesive along their heads, flanks, tails, and legs. One needed part of its tail amputated. Another died the next day from low blood sugar because it couldn’t eat or drink while trapped. These animals suffer for hours or even days before dying of blood loss, shock, dehydration, or suffocation.
Risks to Other Wildlife and to You
Glue traps are indiscriminate. Birds, snakes, lizards, bats, and chipmunks all end up stuck on boards placed for other animals. If you set glue traps in an attic, garage, or near entry points, you’re likely to catch species you never intended to target.
There’s also a direct health risk to you. A squirrel stuck on a glue trap is terrified and will bite or scratch anyone who tries to handle it. Squirrels can carry salmonella in their droppings, ticks that transmit Lyme disease, and fungal infections like ringworm in their nesting materials. A trapped animal continues to urinate and defecate on the board, increasing your exposure to these pathogens. The CDC has specifically warned against glue traps for this reason.
What Actually Works for Squirrel Removal
Live cage traps are the standard tool for catching squirrels. They’re inexpensive, reusable, and far more reliable than adhesive boards. A single-catch cage trap baited with peanut butter, peanuts, or almonds will consistently catch squirrels when set correctly.
A few practical tips make a big difference in success rate. If squirrels are avoiding the trap, try “pre-baiting” for several days: leave the trap wired open with bait inside so squirrels get comfortable entering it before you activate the trigger. If you’re using a trap with only one door, squirrels may hesitate because they feel boxed in. Two-door traps tend to work better because the animal can see through to the other side. If bait is disappearing without the trap firing, the trigger mechanism needs to be more sensitive, or the bait needs to be placed further back on the trigger plate.
Check any live trap at least once a day. A squirrel left in a cage trap for extended periods in heat or cold can die from exposure, dehydration, or stress. If you plan to relocate captured squirrels, release them at least 10 to 15 miles away in a wooded area. Squirrels released closer than that will often find their way back.
Sealing Entry Points Solves the Problem Long-Term
Trapping alone won’t fix a squirrel problem if the animals can keep getting in. The most effective long-term solution is finding and sealing every entry point into your home.
Go into your attic on a sunny day with the lights off. Any gaps where squirrels are entering will show up as spots of daylight coming through the roof, soffits, or fascia boards. Squirrels commonly push up unsecured soffit panels or chew through wood trim near the roofline. Walk the exterior of your house with a ladder and inspect every seam and joint.
Cover any openings with hardware cloth, which is a heavy wire mesh that squirrels can’t chew through. Standard window screen or thin metal flashing won’t hold up. Make sure all squirrels are out of the attic before you seal the last entry point, or you’ll trap them inside, which creates a new set of problems as they chew desperately to escape. Some people seal all but one opening, set a live trap near it, and close the final gap once the attic is confirmed empty.
Combining exclusion with a few days of trapping is the approach most likely to end a squirrel problem permanently, without the cruelty, mess, and ineffectiveness of glue boards.
