How do i know when i need to throw out old packets? Will the packet look eaten through and is that when they should be thrown out?
Dekko Silverfish packs will remain effective indefinitely. When you take the packs out of the box to use in your home, they are good for 3 to 4 months or less depending on the level of infestation and how quickly they are eaten into. They should be replaced every 3 to 4 months whether they looked used or not.
