We have found that warehouses will get 2 types of mice.
1st - Those coming off the land. Conventional mice controls are good at preventing and controlling mice coming off the land.
2nd - Mice coming in on pallets of goods - 'Pallet Mice'. These mice are difficult to control, as they are very anxious (due to new surroundings). Conventional controls are not so effective at controlling this type of mouse. When they first arrive, they often are seen running around during the day, as they are trying to find something they know (and are confused). After a while these mice settle down and join or start a colony. We have found checking the source from where the pallets came from helps, but also large electronic rat traps baited with peanut butter is effective at catching them.
If you need mouse pest control, what works:
1. A cat? Like many buildings in London, Essex and Kent, Downing Street is constantly trying to control and prevent mice infestations. In our experience, cats don't make much difference. In fact, a cat can even introduce a mouse issue - bringing a live mouse as an offering. Cats are pampered and not in the food chain, so rarely perform well as a pest controller for mice.
2. Sonic plugs? We visit lots of places with these, but they still have mice!
3. Snap traps? You'll catch some, but you won't control the mouse issue with just snap traps
4. Glue Boards? They work (the DIY ones don't work that well though), but are cruel and very time intensive - messy as well
5. Poison? Works really well, if you have the right poison, and know what to do with it (cavities are key)
6. Electronic Traps? We have found the rat version of these works very well (but often you can't get them where the mice are, e.g. cavities). Good for 'pallet mice' though.
At MG Pest Control we recommend you have a proper pest control strategy in place to tackle the mouse issue. If you are in Kent, Essex or London, give us a call if you'd like to know how we catch mice.
