It should be placed along walls, by gnawed openings, in or beside burrows, in corners and concealed places, between floors and walls, or in locations where mouse activity or mice have been observed. Certified child and dog-resistant, it comes with a 28 g bait block and cannot be tampered with. Two bait stations may be required where mouse activity is high.
