First, find the active route

Check where droppings or fresh damage are appearing: under kitchen units, beside garage shelving or around the shed wall. These clues help you put the setup where it will be encountered. Scratching in the loft alone does not identify a rat or mouse; use our loft guide before choosing treatment.

Choose traps when you want a visible result

A suitable snap trap is a practical starting point for confirmed rats or mice in an area you can reach and check daily. You can remove the catch and reset the trap. This is particularly useful indoors, where being able to find and remove the rodent promptly is a practical advantage.

Mice are curious; rats are cautious

Mice are generally inquisitive about new objects, so they often approach traps more readily than rats. Rats commonly avoid unfamiliar traps and bait stations at first. This behaviour is called neophobia: a fear of new things. It can make trapping rats more challenging, but an untouched trap after one night does not mean it will never work.

Give rats time to build confidence

Allow several days for rats to approach a well-positioned setup, while continuing your checks. Avoid repeatedly moving the station or changing everything after a quiet night. Where the trap instructions recommend it, baiting a trap and leaving it unset initially can encourage feeding before it is set. If fresh signs are concentrated elsewhere, review the position rather than waiting indefinitely in the wrong spot.

Cover more than one active route

One trap or bait point may miss activity elsewhere. Several well-placed points are often more effective when signs are spread around a room, building or outbuilding. Use the droppings, damage and routes you have found to decide where to put them, keeping each accessible for checks. For poison, follow the product label for the number of bait points, their spacing and the amount at each point. More points does not mean exceeding the label quantities.

Consider poison when another approach is needed

An authorised amateur rodent bait may suit an active infestation where trapping is unsuitable or a properly positioned trapping setup has not solved it. It works over time and still needs regular visits. Buy for the confirmed pest and the exact location on the label; a shed, garden and house are not interchangeable uses.

Using poison indoors: think about recovery and smell

Poisoned rats or mice may die beneath floorboards, inside walls or in another hard-to-reach space. Their bodies can cause an unpleasant smell, and locating or removing them may be difficult. Traps positioned where you can check and retrieve them give you more control over finding and removing the catch. Consider this difference when choosing a method for the house or loft.

Before changing products, check the basics

Remove other easy meals so your setup has a better chance of being visited. Check traps daily and follow their instructions. With poison, follow its inspection and treatment instructions, including searches for dead rodents. Record fresh droppings, feeding and catches so you can see what is changing. Persistent activity deserves a fresh look at the entry route, not just more bait.

Build the setup, then keep them out

Choose our Rat Box for a compatible rat trap or bait setup, or a Compact or Double Mouse Box for mice. Each includes a key; traps and poison are separate. The lockable housing helps prevent children, pets and wildlife from reaching the contents. Secure it as instructed and keep it locked between checks. Plan proofing alongside treatment and finish active entry-point repairs once animals are cleared.
