Around here its best to go a day or two before you are going to use it .We do it to get the varmits out ,wasp ,snakes or whatever .I went to one during hunting season that Ihad not checked ,it had a nice swivel boat seat in it .I sat down and felt something move ,it was a black snake about 3 ft. long .It jumped out and hit the ground ,I laughed so hard that I did not see a deer .
