A: I get this question often, and not every job will require one. People ask me if I charge just to come look at your house...yes I do but I am there to do more than just look at it. You can hire a carpenter to look at it, but he will not know the common points of entry and or how to make your home animal proof.
Anyone can set a trap, but it takes knowledge of how animals move about, reproduce, forage, and gain entry to completely solve your nuisance wildlife control problem.
I go into the attic, and I go under the house if need be. I walk the property, and I observe the game trails that exist - that the animals see! I identify droppings, hair samples, footprints,etc and put it all together in a plan that will give you back your home.
I do this every day and I have the experience it takes to solve your problem.
