Check for Nests
Many species prefer to nest or den in cavities; chimneys, eaves troughs, undisturbed brush piles and old trees are perfect spots to raise a litter in the spring and warmer months. In the winter, if left unsecured animals will find their way into any cavity or crevice they can access to stay warm.
Secure openings and cap chimneys to prevent entry. Capping a chimney will prevent many species of wildlife from roosting or denning in your chimney, like bats, starlings, sparrows, owls, squirrels, wood ducks, and raccoons.
Check chimneys before cleaning and lighting.
Check vent and soffit covers are secure.
Prevent entry under porches or decks with fencing or hardware cloth.
Inspect trees, branches and shrubs before felling, removing or burning brush piles.
Most birds fledge within a few weeks, so it’s best to wait until the nest is empty rather than trying to relocate the family. Mammals are best left undisturbed whenever possible, at least until they start exploring outside the nest.
In Ontario, it is illegal to disturb or destroy the nests of most birds and mammals.
