ADC and Wildlife control now days are basicly the same thing, just depends on the era and location the person is in and came from, on which term they use. Back in the late 70's Adc was a term used by the fed and states for people that dealt with manly predators or depredation and beaver problems. The job was for the most part trapping. That is how I started, doing depredation work and some predator (fox,coon and skunks Raiding and killing poultry, rabbits and in some cases fox on lambs)when the urban and suburban work started to really take off in 80 to 83 the term was urban wildlife control then switched to wildlife control. The ADC guys like my self, here on the east coast, and around the big towns, soon started doing squirrels and house dwelling coons and such. moles and ground critters like chipmunks and skunks. repairs came into play with the job, So I guess if there is a difference, today in the terms it would be ADC are manly trapping and wildlife control is trapping, harassment, exclusion, repairs, consultation, changing the habitat for less animal use (For the Life of me I can't remember that word LOL) a more encompassing field. and covers bats to hippos. LOL But I really do not expect to see many ADC that is not doing the wildlife control. so it is the same except for some of those only beaver or coyote men.
