QuestionCan i use ammonia to get rid of racoons
AnswerYes, but it is like asking me if you could exceed the speed limit to get to work on time. The answer is yes, but you shouldn't do it. Ammonia is not registered for work on raccoons so your use would be a violation of federal law and they get touchy on those things.
Second, the amount of ammonia you would have to use might drive you out of the house. Third, depending how it was administered, it could be seen as cruel and still not work.
So what do you do? Simply, first, determine if it is a male or a female with young. Then check your state laws. Can you trap? Once trapped what do you do with the animal? To get the laws visit http://icwdm.org/VendorsService/default1.asp click your state and contact them.

Then if it is a male, then trap it and dispose of it according to state law. If a female, then it becomes more tricky as the young may not be mature enough to leave with her. If you can reach the young, then trap her and then grab the young. Yes, you need proper protection, gloves, eye-protection, Tyvek suit, HEPA filter mask, properly seated etc.
Once you have the animals, then follow the instructions on checking to see if there are any more animals.http://icwdm.org/Inspection/techniquepaperhole.asp
Animal damage control is not rocket science. But it requires patience and attention to the steps. Failure to follow the steps and cut corners can be disastrous. A word to the wise.
