The Victor Easy Set Gopher Trap effectively kills gophers without the use of chemicals or poisons. The trap features galvanized steel construction for superior strength and durability. The trap’s narrow design with short base allows for easy insertion into gopher tunnels and keeps moving parts completely below the surface, safely away from children and pets * Victor Easy Set Gopher Traps are easy to use and come fully assembled and with illustrated operating instructions on setting and placement. As the most reliable gopher trap on the market, you can rest assured that your yard is safe from the damaging effects of gophers. * Victor Easy Set Gopher 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.
