Back in the 1930s a test was done on Noman's Island off Massachusetts, introducing a tiny parasitic wasp to control ticks. It was reported to have reduced the tick population by 50% which can carry five different kinds of disease. Maybe the tick's natural predators were once more numerous in the Northeast US extinguished by pesticide or other factors, i.e., wide-scale forest clearing, etc.
