I have used a few boxes of bromadiolone bait over the last couple of weeks and I still have mice?
• The rodenticide is likely killing off mice that are being replaced with new mice or you have a larger population than first suspected. Unfortunately mice will want to live in areas that are desirable to mice. The trick is to make the area less desirable. To do this you have to think like a mouse (or hire a professional). • First, make sure all small holes around your house foundation are sealed. Mice can fit through a ¼ inch hole. Check around pipes, wires, windows and doors. • Secondly, Mice love clutter and hate open spaces. Basements, garages and storage rooms often can get fill with boxes, old furniture and stuff that mice can hide and nest in. If mice are in an area like this it must be cleaned up. • Continue to use a bromadiolone bait as well as traps.
