It is important to know what kind of wildlife is causing the problems. Knowing what damage has been done and if there are any young animals will help in the process of removal. Once the specialist has that information, then they will know what management procedures to use to resolve the problem. They will take into consideration what kind of impact removal will have on the animal. They will also take into consideration the likelihood of the animal coming back along with the safety of people or household pets.
Actual removal should be the last step. Once armed with all of the the necessary information only then is it time to remove the animal. Removal needs to consist of human strategies. These include the use of animal repellents all the way to modifying the habitat. If the specialist you have called does not use humane strategies, then call one who does.
There are some things that you should discuss with the wildlife extractor. You want to know if removing the animal will solve the problem or just take care of the symptoms. Make sure that the solution includes addressing the underlying cause so that it is effective.
If you are having a problem with wildlife be sure to call an extractor that practices humane removal procedures. It is alway best to leave the animal alive and just remove it from your home.
