Warfarin Block Mouse Bait Station

Former name: Wilson® PREDATOR® WARFARIN™ Mouse Bait Station

The mouse you use to move a cursor around your computer screen is a good thing. Indoor mice, on the other hand, are a very bad thing. They’re extremely unclean, leaving urine and feces. They also may be covered with ticks, which can transfer to pets, and in turn transfer to human beings, potentially infecting them with diseases like Lyme disease, Colorado tick fever and, believe it or not, the bubonic plague. Don’t let mice plague you any longer! Get one, or several, MOUSE OUT Warfarin Block Mouse Bait Stations. The stations contain warfarin, an anticoagulant chemical that reduces the clotting ability of the blood. After several feedings, house mice die from fatal hemorrhaging and your mouse plague should be history.

How to use Wilson MOUSE OUT Warfarin Block Mouse Bait Station

Step 1
Remove alternative sources of food in the area where you intend to place bait stations.

Step 2
Place bait stations in locations frequented by house mice such as near holes or runways, against walls or in corners where house mice are seen.

Step 4
Place bait stations at 2- to 5-m intervals, using the smaller interval in locations where there is a high level of house mouse activity observed.

Step 5
Mice must feed on bait two or three times before they die. An uninterrupted supply of bait should be maintained for at least 15 days. Monitor bait through clear lid in bait station. If bait has run out, replace with new bait station.

Always put bait stations in areas where there is a lot of mouse activity. If you see mouse droppings, this is a sign that bait stations should be placed in that room. Place stations along the walls and edges of your room. Mice aren’t likely to go through the centre of the room unless they are being chased. Instead, they tend to scurry along the edges of your room. Put traps along the walls near entry points like doors and windows. Place a shallow container of drinking water near bait stations to encourage consumption of bait.


Move your stations to different areas if nothing has been caught within a few days of putting them in place. Sometimes you have to experiment with placement to figure out what will work inside your home. It is essential to get as many mice as possible to take the bait in order to rid your home of an infestation quickly.


Warfarin Block Mouse Bait Stations can also be used as a preventative option, in areas in your garage, basement or attic year-round so you don’t end up with an infestation.


Place bait stations at 2-5 m intervals, using the smaller interval in locations where there is a high level of house mouse activity observed. An uninterrupted supply of bait should be maintained for at least 15 days. Monitor bait through a clear lid in the bait station.

Whenever you see mouse droppings, you know that you have an unwanted visitor. Mice reproduce quickly. You can be almost certain there are more than one. To control mice, you need more than one or two bait stations to eliminate the problem quickly. The most effective strategy is to place one mouse station every 2 to 5 meters along the wall where you've seen signs of activity.

Although one mouse is not considered an infestation, you need to consider that a single female can have 5-10 litters a year, with 6-8 babies each time. A newborn female mouse can start breeding at 6 weeks of age.It is important to nip the problem before it escalates!
