Rat Snap Traps

A rat snap trap is a mechanical device that delivers a fast kill with no poison. When a rat puts weight on the bait pedal, a spring-loaded bar closes instantly. Because there is no active substance involved, there is no secondary risk to a pet or bird that might scavenge the carcass.

For the best results, we recommend using the PestBuddy Non-Toxic Rodent Attractant. It is highly aromatic and designed to stay put on the trap pedal rather than drying out or being carried off, which matters because rats are wary of new objects and often take days to approach a trap.

Use a pea-sized amount pressed into the pedal, not a generous smear - overbaiting is the commonest reason a trap gets emptied without firing. Read our guide to the best baits for rat traps to see how food baits such as peanut butter compare.

More than most people buy, and the spacing depends on where you are setting them. Roughly 1-2m apart in hotspots where droppings are concentrated, 3-5m along walls and the routes rats travel, and around 10m apart outdoors. Set as many as you can on the first night - rats grow warier of traps over time. A single room usually needs three or four; a loft, cellar or outbuilding needs more.

Place the traps in areas where rats are most active, such as along walls, near food sources, or in hidden corners. Position the traps perpendicular to the wall, with the bait end facing the wall to maximise effectiveness. Our guide to setting up a rat trap walks through it step by step.

Start by working out which of these you have.

Bait disappearing, trap not sprung. You are using too much. A pea-sized amount, pressed firmly into the trigger pedal or smeared just underneath it, so the rat has to work at it rather than lick it off the surface. A generous smear lets it feed from the edge without ever putting weight on the pedal.

Bait untouched. With rats, the commonest answer is simply that they haven't approached yet - they are neophobic, wary of anything new on their runs, and often take several days. Leave traps in place rather than moving them around. Beyond that: too few traps, wrong placement (tight to the wall, at right angles, trigger end nearest the skirting, where you have found droppings), or your scent on the trap, so wear gloves. If nothing changes, leave traps baited but unset for two or three nights so the rats feed confidently, then set them all on the same night.

If placement and baiting are both right and a week still gives nothing, question the target rather than the method. Old droppings look much like fresh ones, so the activity may have moved on or already stopped - trap where you are finding fresh droppings, not where you first heard something. And scratching overhead isn't always rats; squirrels and birds in a loft sound very similar and won't go near a rat trap.

Catching steadily is a good sign, but if new rats keep arriving after a week, something is replenishing them. Usually one of three things: an unsealed entry point letting new rats in from outside, a nest or harbourage nearby that is still producing, or too few traps to keep up with the numbers. Work round the outside and close the gaps with proofing, fit a drain guard if the drains are the route in, and add more traps rather than moving the ones you have.

Yes, many rat snap traps are designed to be reusable. Simply clean the trap thoroughly after each use to remove any odours and reset it with fresh bait.

A set rat trap has a powerful spring and is a mechanical hazard, so placement matters. Keep traps out of reach of children and pets, or house the trap inside a lockable rat bait station, which lets the rat in but keeps fingers and paws out. That is the sensible option anywhere a dog goes, indoors or out.

Always wear gloves. Release the rat from the trap, using tongs or a shovel rather than your hands, and, still wearing your gloves, place it in a plastic bag. Seal that bag, place it inside a second bag, and put it in your outdoor bin. Clean and sanitise the trap before reusing it.

Check them daily. A rat left in a trap becomes a hygiene problem, and an empty trap tells you something too. Checking is not the same as moving, though - look, then leave the trap exactly where it is. Rats are wary of anything new on their runs, and shifting traps around between checks is one of the commonest reasons people stop catching anything.

Trapping clears what is already inside; it doesn't stop new rats getting in. Seal the entry points - a rat gets through a gap of around 15mm - using wire wool, sealant, door sweeps and air brick covers, and fit a drain guard if the route in is the drainage system. Then remove what drew them: food in airtight containers, bins closed, spillages cleared.
