Mosquito Repellent Patch Natural Lemon Eucalyptus works pretty good. We had Issues with our son being bitten up by Mosquitos every night. I used one of the patches to put at the top of his bed and it worked amazingly. When you first open the package you can smell how strong the patch is. Their simple to peel and place where you want and then easy take back off when finished using it. We also went to our cabin for the fourth of July and used this product. We didn’t even really notice mosquito’s at all except here and there.
