Large attic with silverfish problem in some areas. Grandchildren occasionally like to go get things from the attic so I want to use removable trays instead of spreading around. How long will it last?
Niban can be put in removable bait trays such as a bait plate station in the attic area. You should plan on replacing the bait every couple of months to ensure it is still fresh.
