Drenjoey, we have had mice and small squirrels in our last TT and lots of mice in a 115 year old house but since we started using the orthro animal be gon none in the new TT and almost none in the house. So I think it really does send them to other places. You still need to block the easy access route and keep grass,weeds,leaves down to make it less likely to provide cover for them to look for egress into your property.
