Unwanted birds are not only annoying, they can also cause a lot of damage to property. Bird droppings are acidic and eventually destroy paint. Bird nests can block proper ventilation and produce offensive and dangerous odours. They are especially dangerous in chimneys because they can cause carbon monoxide build-up and become a fire hazard. Bird nests also contain mites, ticks, fleas and other parasites.There are number of things that homeowners can do to prevent bird problems.
Locate the bird nests in and around the roof. Birds naturally seek warm places to build their nests and these places usually include chimneys, attics, vents and eaves. Listen for bird noises and watch where birds are landing. Bird nests will also give off offensive odours.
Clean out all the nests and block future access. If birds are roosting in the chimney place a mesh topper on the chimney after removing all the old nests. If they are inside the roof or eaves, remove the nests and patch the holes. Put a cloth or mesh netting over the vents. This will allow the vents to work but prevent the birds from building new nests.
Place bird spikes along the roof where the birds are landing. Bird spikes are stainless steel tack strips similar to the ones that police use to stop vehicles.
Apply sticky repellents on the roof. This will make it uncomfortable for the birds to land. There are various products such as Tanglefoot and Roost-no-More.
Set up visual and audio decoys. Bright shiny objects, plastic owls or devices that emit the sound of a predator will frighten birds and prevent them from landing on the roof.
Don't remove nests that contain eggs or baby birds. Depending on the species, it may be illegal. Check local laws.
