Are mouse traps safe to use with a dog in the house?

A quick-set snap trap placed out of a dog's normal path, such as behind furniture or along a skirting board, is generally safer than loose poison bait, since there's nothing edible for a dog to find. It's still worth positioning traps somewhere your dog doesn't routinely sniff around.

Could a fly paper harm my cat if she brushes against it?

It can be an unpleasant, sticky mess to clean off fur if a cat gets close enough to touch one, so hang fly papers somewhere out of normal cat reach, such as higher up or away from favourite perching spots, rather than at cat height.

Why avoid poison bait if I have pets?

Bait has to be eaten to work, which makes it something a curious pet could also eat, and there's an added secondary risk if a cat catches and eats a rodent that's been poisoned. A mechanical trap removes both risks.

What should I do if my dog gets caught in a snap trap?

Check for any injury to the paw or nose and contact your vet if there's swelling, bleeding or your dog is clearly in pain, since even a quick-set trap can pinch hard enough to need a proper look.

Household pest control for a home with pets

In a home with pets, mechanical traps and physical barriers are generally the safer route for household pests than anything a dog or cat could eat or lick, which is why this aisle is built around snap traps and fly papers rather than loose poison bait.

Why a mechanical trap is usually the better choice

A snap trap works by catching the pest physically, with nothing edible left lying around for a curious dog or cat to find. Poison-based rodent bait, by contrast, has to be eaten to work, which means it's also something a pet could eat, and a poisoned rodent can still pose a secondary risk if a cat catches and eats it.

Fly papers work the same mechanical way for flying insects — nothing to eat, just a surface a fly gets stuck to — which makes them a straightforward option for a kitchen or utility room where pets are also around food.

What's actually in this aisle

Snap-style mouse traps come pre-baited or ready to bait yourself, and a quick-set design means less handling of the trap once it's sprung. Fly papers are the simplest option for flying insects and need no setting at all — just hanging somewhere flies pass through.

None of what's here is a poison or a spray-based rodenticide, which is a deliberate choice for a range aimed at homes where pets have the run of the same rooms as the pest problem.

Placing traps safely around pets

Set traps along walls and in the gaps behind furniture where rodents actually travel, rather than out in open floor space where a curious dog or cat is more likely to investigate and catch a paw or nose in a snap trap. A trap tucked behind an appliance or under a low unit does the job just as well and is out of a pet's normal path.

Check traps daily rather than leaving them for days at a time, both for effectiveness and so a caught pest, or an accidentally sprung trap, doesn't sit somewhere a pet could get to it.
