You really think it would be easy to do? You are talking about a rather small creature that exists all over the place. Attempts have been made but total elimination is going to be rather difficult and expensive. At least two approaches have been attempted and failed. Insecticide impregnated cotton for the mice to collect and use as nest material was tried years ago.in addition to info in the second video, elimination of the black-legged tick would eliminate ALL Lyme disease. Without the vector (the tick), several dozen of the small mammals, including the white-footed mouse, carriers of the spirochete bacterium, would be rendered completely harmless. How hard could it possibly be to get rid of black-legged ticks in an age in which we can space travel…..gimme a break! Where there’s a will, there’s a way!
Currently there are deer feeding stations available that have insecticide impregnated rollers on them. The deer has to put its head between a pair of the rollers to feed on corn inside a barrel.
Most of the ticks attach to the head and neck of the deer. This method has been fairly successful in areas it has been used in.
The problem probably comes down to funding. The same issue happens with rabies control in wild life. An oral bait has been developed yet no county wants to spend the money to drop it in areas it is needed.
Space exploration is much more attractive than bug spray and vaccines.
