you can use an ash ring around your food area ie cool box or bag to stop ants, spiders, rats and any small mamals getting to your food and in the tropics to stop snakes getting in your camp. just go around your whole camp big time with a bigger ring. because they don't like getting ash on their feet, especially snakes don't like anything sticking to their skins, you never see a dog or a cat very close to a fire place. try putting some ash on dog or cats paws. and see. they hate you for life. cheers the interceptor boy.g sticking to their skins, you never see a dog or a cat very close to a fire place. try putting some ash on dog or cats paws. and see. they hate you for life. cheers the interceptor boy.
