When birds choose trees on your property as their roosting spot, you must be prepared for the noise and waste that results from their presence. Sometimes, birds can become quite a nuisance prompting you to seek a solution to rid your trees of them. Deterring the feathered creatures, instead of harming them, is likely the best solution, as there are many birds that are protected by local, state and federal laws.
Remove all bird feeders or birdbaths in order to keep from encouraging birds to visit your property. The more hospitable you make the area, the more likely the birds will choose to roost in your trees.
Prune the branches of the affected trees with pruning shears or a hack saw to thin out roosting areas. A little trimming may have a substantial effect.
Cover your trees with nylon or plastic netting material to keep birds from landing in the branches. If you have fruit trees, netting will also prevent them from eating the fruit.
Play a recording of bird distress calls within hearing distance of the roosting area, beginning 1 1/2 hours before dark until dark, for five to seven evenings in a row. The distress calls signal to the birds that a predator has caught one of their own. It will disturb them and should eventually discourage them from roosting in the tree.
Make a hole in the side of an aluminum pie plate with a knife and insert a piece of string through the hole. Use a long enough piece of string so that you can tie the plate onto a tree branch. The shiny appearance and movement in the wind may make the birds nervous and unwilling to roost. The more plates you hang, the more effective it may be to deter the birds.
