Gopher trapping can be done at any time of year, but generally is easiest and most effective during Spring & Fall. Once gopher activity is detected it is important to move quickly as pregnant females can be caught before giving birth to her family. Traps are most effective when placed in the gopher tunnel and with 2 traps back to back. The hole should be covered up with dirt so that it appears as if the trap is part of the runway. When used correctly, traps produce a catch within 48 hours. It is best to move the trap to another location in the runway if you do not catch a gopher in this timeframe. Easy set gopher trap 2 pack.
