I used it a few times this year and it really keeps the mosquitoes away.....I don't like the way it burns and stings my neck and face though. It smell like fall decompsed leaves at firs and shortlty turns into a smell of alcohol.....I hunted about 3 times with it but didn't have any deer within sight......I'm not sure it would spook them, but I'm not sure it would not either......I sure would like to know..
