Abstract: A method of repelling rodents and vermin comprising the steps of providing an effective quantity of dry dusting sulfur and inserting said dusting sulfur into burrowing holes and other spaces traveled by rodents and vermin. The method is primarily directed to gardens and yards where animal burrows are evident, but will work in agricultural fields and living structures as well. In the latter application, the dusting sulfur may be applied, for example, in pipes, underneath floor boards, and inside wall and crawl spaces.
