I used this on a journey I took on my Motorcycle camping thru California, Nevada and Utah. I used it many times as a barrier around my ground cover. I watched many creature try to cross with no success. I did have what I call the kamakazi ants at Mono Lake. They would take runs at the barrier and pass out or die. It was crazy to watch. They first just tried to pass the barrier I sprayed around my tent on the ground cover. They frist tried to walk thru it .....and upped the game to take the wfo toward the barrier, hitting it and passing out or dieing. Some would try several times.The product is solid. Let it dry before entering into the tent, fumes are strong, once it dries I didnt notice a strong odor as when its wet.
