Glue traps work for mice only under narrow conditions: flush against a wall in a confirmed travel lane, free of dust, and checked every two to three days. They catch mice already inside your home but do nothing to stop new ones from entering. Used alone, they manage a symptom, not the cause.
How a Glue Trap Actually Catches a Mouse
A glue trap is a flat board coated with a strong pressure-sensitive adhesive. A mouse runs across it, its feet stick, and the harder it struggles, the more of its body gets pulled into the glue. That struggling detail matters later when we talk about disposal, because it's the reason a stuck mouse rarely frees itself on its own.
When Glue Traps Actually Work
We still carry glue boards on every mouse call because they genuinely earn their spot in a high-traffic travel lane.
- Flush against the wall behind appliances: Mice hug vertical surfaces as they move, so a board tight against the baseboard behind a fridge or stove intercepts them mid-route.
- Under sinks and in cabinet toe-kicks: Tight, dark, confirmed travel lanes where a board won't be disturbed for days.
- As a monitoring tool: Before we commit to a full trapping and exclusion plan, we'll drop boards in suspected zones for a night or two just to confirm activity is actually there before quoting the job.
Why Glue Traps Fail: Placement, Dust, and Large Mice
Every glue trap failure we get called out to fix traces back to one of three things.
- Placement in the open: Same mistake as a snap trap. A board sitting in the middle of a floor, away from a wall, gets ignored because mice don't cross open space if they can avoid it.
- Dust and debris: Under stoves, behind fridges, and near insulation, airborne dust and grease settle on the adhesive within days. Once that surface is coated, a mouse can walk right over it. In these specific zones we replace boards every two to three weeks, not months.
- Large mice: A big adult house mouse has enough body weight and strength to pull free from consumer-grade adhesive. Professional glue boards use a significantly stronger adhesive spread over a larger surface area, which is why the ones we install hold where a hardware-store version won't.
Field tip: If you're finding tracks or droppings crossing a glue trap without it catching anything, don't assume the trap failed. Check the surface for a fine layer of dust first. That's the more common cause than a "smart" mouse.
The Disposal Problem Nobody Talks About
A live mouse stuck on a glue board is a situation most people are genuinely not prepared for, and it's a real limitation of the product, not a rare edge case. Small mammals caught in glue traps suffer real distress, and their own efforts to escape typically cause them to become further stuck. The Canadian Veterinary Medical Association has stated that glue traps are not considered an acceptable method for capturing or killing vertebrate animals because of the suffering involved. Beyond the welfare question, handling a struggling, stressed animal and its waste also carries a direct hygiene risk. Salmonella and Leptospirosis can spread through contact with droppings and urine if hands aren't washed immediately after, which is exactly the kind of contact a live catch forces on whoever finds it.
What a Glue Trap Will Never Fix: The Entry Points
This is the part that gets skipped in most product reviews. A glue trap catches a mouse that is already inside your home. It does absolutely nothing about the gap that mouse used to get in, and that gap doesn't close itself.
The first line of defence against mice is eliminating easy entry points, since mice can squeeze through cracks as small as a dime. In our experience, the only gaps worth sealing are exterior ones: foundation cracks, pipe penetrations, weep holes, vents, and garage door corners. Interior gaps like baseboards or attic hatches aren't entry points at all, they're just travel routes a mouse uses once it's already inside, and sealing them only pushes the mouse to find another route through your walls without solving anything.
Mice also mark these travel routes with urine, and that scent trail can persist for months, pulling new mice to the same opening long after the first one is gone. In Ontario, that pattern gets worse every fall. Freeze-thaw cycles through September and October shift foundations slightly, opening new hairline gaps that weren't there the year before, right around the time the season's first cold spell sends mice looking for a heated building to shelter in.
How AstraHive Pest Control gets rid of mice
Mice get in through small gaps, so the lasting fix is at the outer shell of the building. We find the entry points, close them from the outside and deal with the mice already inside.
How an AstraHive mice treatment works
Inspect and find the entry points
We inspect the outside and inside of the building for droppings, gnaw marks, runways and every gap. A single property usually has several entry points, not just the one you noticed.
Seal the exterior entry points
We seal the exterior only: foundation cracks, utility and pipe penetrations, vents, weep holes, rooflines and garage door corners. Gaps are packed with steel wool or copper mesh locked in with sealant or foam, and larger openings get hardware cloth. Foam or caulk alone is not a rodent barrier.
Trap and bait where needed
Mice already inside are removed with traps and with tamper-resistant bait stations, inside and outside where needed, using Health Canada approved products applied according to the product label.
Flag structural damage and report
If we find structural damage that needs repair beyond what we can seal, we flag it in the service report, along with every observation, every entry point found and every product used.
Follow up and back it with a 90-day warranty
We come back to re-inspect, refill the bait stations and make sure everything is holding. If mice return within 90 days, we re-treat at no charge.
Our products are Health Canada approved and safe for kids and pets, and we apply every product according to its label. AstraHive is licensed by the Ontario Ministry of the Environment, Conservation and Parks. Ontario requires a ministry-approved certification course before it issues an exterminator licence, and that training is delivered through the University of Guelph, Ridgetown Campus.
Sealing is what ends repeat visits. Traps and bait only remove the mice that are already inside, and new mice keep coming for as long as an exterior entry point stays open.
Sealing lowers the risk a great deal, but it cannot make a house completely mouse-proof. Mice can chew new ways in through the softer parts of a building, such as the rubber seal on a garage door, weatherstripping, siding, wood trim and the plastic coating on wires, and a house keeps shifting and ageing, so gaps that did not exist on the day of the work can open later. Chewing can also damage the structure itself, including wiring, insulation and framing, and that wear and tear can continue after every entry point we found has been sealed. We record the damage we find so you can arrange repairs, we check at the follow-up visit that the seals are holding, and anything new that opens up afterward is a new entry point rather than a failure of the old work. If you see fresh gnaw marks or droppings, or hear scratching, call us early.

Frequently Asked Questions
Are glue traps a humane way to catch mice?
Most veterinary and animal welfare organizations, including the Canadian Veterinary Medical Association, do not consider glue traps a humane method because trapped animals can remain alive and distressed for an extended period. That's a legitimate concern worth weighing against snap traps or professional exclusion-based control, which is the approach we lead with.
How often do glue traps need to be replaced?
In dusty areas like behind fridges, under stoves, or near insulation, replace glue traps every two to three weeks since airborne dust and grease coat the adhesive and let mice walk right over it. In cleaner, drier spots the adhesive lasts longer, but check it every few days regardless.
Can a mouse pull itself free from a glue trap?
Yes, a large adult mouse can pull free from consumer-grade glue trap adhesive, especially if the board has picked up dust or debris that weakens its grip. Professional-grade glue boards use a much stronger adhesive over a larger surface area specifically to prevent this.
Will glue traps stop mice from coming back into my house?
No. A glue trap only catches mice that are already inside; it does nothing to close the exterior gap they used to enter, such as a foundation crack or gap around a pipe. Mice also leave urine scent trails at entry points that can attract new mice for months, so the opening needs to be physically sealed to stop the cycle.
What should I do if I find a live mouse stuck on a glue trap?
Avoid direct bare-hand contact, since handling a stressed, struggling animal and its waste carries a real risk of exposure to Salmonella or Leptospirosis if you don't wash your hands immediately after. If you're not prepared to deal with a live catch, this is a good reason to call a licensed technician rather than handle it yourself.
