How effective is this ground-injected fumigant method for gopher or squirrel control?
It is VERY effective, mostly because the first instinct gophers or squirrels have when threatened is to go deep underground. That works because our system pumps the fumigant throughout the burrow system, and the pests cannot escape it. The fumigant is a widely available, non-restricted-use pesticide that leaves no significant residue.
