An apparatus and a method for eliminating termites, roaches and other insects from homes by injecting the ground with uniform amounts of exterminating fluid. To be effective in eliminating these pests and to meet state environmental regulatory laws, it is important that the right quantity of exterminating fluid be injected. This invention provides a means for electronically recording the time length of an initial injection and by audible tones advise the user when an identical time length has elapsed on subsequent injections. By use of this timing mechanism, the user can be assured that a uniform amount of exterminating fluid has been injected with each use of this exterminating fluid injector.
