I bet the answer is yes.
Fortunately there is a natural and safe way to rid yourself unwanted rodents - install a Barn Owl nest box on your property!
OUR NATIVE FRIEND
Barn Owls are a native owl species who like to nest in the hollows of trees and, of course, barns. Unfortunately there aren't many old trees or barns around. Old dead trees with hollows have mostly been cut down for firewood or to reduce the risk of wildfires.
BARN OWLS' FAVORITE MEAL =
GOPHERS, RATS AND MICE
The owls are also very small, weighing about a pound, so you don't have to worry about pets being injured.
Many factors go into play when an owl is looking for a home. These factors include the size and shape of the box, opening size, mounting height, mounting substrate, sun angle, box door accessibility, relative grade slope to box and many others. After studying raptor ecology for over 10 years we can ensure your nest box is placed in the best way to get owls.
DO NOT USE POISONS - EVER
Even poisons that state on the package that they are safe or do not cause secondary poisoning are construing the truth. Secondary poisoning is when an animal, like a coyote, eats a gopher you poisoned, and then get poisoned themselves. The claim that a poison does not cause secondary poisoning means that once a poison is digested by the primary animal, the gopher in our example, it is no longer poisonous to the secondary animal, the coyote. This is true, however, most of the times, when the primary animal dies, it still has undigested poison in it's stomach and therefore will poison anything that eats it!
