I got asked a fantastic question yesterday!
‘I don’t want to use bait in my yard. How do I reduce the Mouse population?’
You can attract owls to your property, they are the most effective mass hunters on the planet!
In Australia, a pair of barn owls can consume over 3,000 mice annually. A study in Hillier SA, found that nine pairs of barn owls and their owlets ate 5,000 mice within a six-month period. The majority of the eastern barn owl's diet, which is over 90%, consists of house mice.
One of the biggest problems we have is that rat and mouse bait is the biggest killer of birds of prey! Please, please stop using it. You can attract owls to your yard….
Here's a more detailed approach:
1. Habitat:
NO CATS - you need to ensure that your property and the area that you are trying to attract the owl to is not accessible or populated by Cats.
Trees and Perches: Owls need trees for roosting, nesting, and hunting. Keep native trees, especially those with potential for natural cavities, and don't prune large branches. Offer perching spots like fence tops, bare branches, or installed perches.
Brush Piles: These provide shelter and hunting grounds for small prey that owls eat.
Longer Grass/Weeds: Unmowed areas provide cover for prey, making your yard more appealing to owls.
2. Nesting:
Owl Boxes:
Install an owl box, ensuring it's made of untreated wood and has an appropriate sized entry hole (3-inch-by-4-inch oval or 3-inch diameter round).
Location:
Place the box near tree lines but not too close to dense woods, especially if Great Horned Owls or Red-Tailed Hawks (Barn Owl predators) are present.
Natural Cavities:
If possible, leave dead trees or large dead limbs standing as they often have natural cavities used by owls.
3. Food:
Prey:
Small rodent populations (voles, mice) as they are a primary food source for many owl species.
Water:
Provide a large, deep bird bath or a small water feature, ensuring safety for smaller animals by placing stones on one side.
4. Other Tips:
Minimize Light Pollution:
Owls are nocturnal, so reduce outdoor lighting, especially floodlights, to minimize disturbance.
Learn About Local Owls:
Research which owl species are common in your area and their specific habitat preferences.
By creating a welcoming environment for owls, you can increase the likelihood of them choosing your yard as a home.
