but if i do can birds still move inHow do i keep squirrels from moving into my bird house, should i try wire mesh...?
the easiest way to fix this problem is to use birdhouses with smaller entrance holes. if they're too wide the squirrels will be able to make theirselves comfortable. smaller entrances will prevent them from getting in. also don't include perches because that is a good grip hold for squirrels and other predators that may want to enter.How do i keep squirrels from moving into my bird house, should i try wire mesh...?
Its a problem most people have with squirrels. They like to eat bird eggs from time to time. You can't use wire mesh cause the birds definately will not be able to use the box. You just have to keep shoeing them off. Don't put little perches on the outside of the box for the birds to stand on, it only makes it easier for the squirrels. Normally squirrels don't move in to the nest box...they like to be high up in the trees, they just like to get into the nest for the eggs.
Build them both houses.





Nice ones with cable and wifi.
