The American Bird Conservancy states that UC California researchers have found second-generation anticoagulant residues in 70 percent of the mammals examined and 68 percent of the birds.
Let’s face it: rats, mice and gophers can all be really pesky pests, causing damage to valued plants and ruining foodstuffs as well as being disease vectors. Cute as they are sometimes, if we’ve got critters in the wrong place at the wrong time, we want them out! So what to do in place of using the toxic rodenticides?
* Don’t leave pet food outside overnight
* Store food in rodent-free containers
* Keep garbage areas clear
* Pick up fallen fruit
* Plug holes in buildings, eliminating gaps larger than 1/4 inch wide (pencil eraser size)
* Use gravel breaks along foundations (rats don’t like to run on gravel) and break up ground cover areas to prevent hidden “runs”
* For gophers, use wire netting or gopher cages to protect plants (hardware cloth or 3/4 inch poultry netting)
If you’ve got the stomach for it, trapping is an option, but use only lethal traps, maintained regularly. These can include “snap” traps or electronic traps, but glue traps are not recommended as they aren’t especially effective and are not humane.
These owls are fearsome rodent catchers indeed. Consider putting up one or more Barn Owl nest boxes to encourage these wonderful birds to help keep the rodent population near your home in check.
