The Pest-Stop Snap Mouse Trap is pre-baited with a mixture most mice find irresistible - a mixture of peanut oil and molasses. It is easy to set with a simple click, and can even be set using just one hand. It is extremely safe to use. No need to touch dead mice; simply release by pressing down on the tab - the trap will then be ready for re-use Please note: Mice carry a variety of diseases, and should never be handled without protection. To minimise distress to captured mice, traps must be checked regularly (preferably every 2 hours), and should not be left overnight.
