Bradford pear trees grow throughout China and Japan, and produce lovely, fragrant pears that bloom throughout the late spring. Bradford pears are used for many Asian dessert dishes and for making wine. In North America, Bradford pear trees are used for aesthetic purposes, as the trees will not bear fruit but do produce aromatic spring floral blossoms. Pests of the Bradford pear tree include a variety of worms and beetles, which harvest the leaves and cause the tree to decay. Because Bradford pear trees can grow to a height of 25 feet, it is necessary to use caution when ridding the tree of pests, particularly while using a stepladder. Eliminating pests on a Bradford pear tree does not require specialized gardening skills and can be accomplished with a few simple tools.
Remove any fallen branches or leaves from underneath your Bradford pear tree.
Discard into plastic trash bags or compost bin.
Use your garden hose with spray nozzle attachment to spray your Bradford pear tree. Be sure to thoroughly coat the tree with water, and use your stepladder to reach the top of the pear tree.
Fill a large spray bottle with 1 cup insecticide and 4 cups of water. Mix well.
From a distance of 8 inches, spray the pear tree with the insecticide solution. Start with the areas you are able to reach from the ground level, working your way around the tree. Use the stepladder to spray around the top of the tree.
Leave to dry, do not rinse off. The insecticide solution will continue to work over the course of two weeks' time. Inspect your pear tree after two weeks to ensure it is free of pests, and if necessary repeat the insecticide solution to keep your Bradford pear tree free of pests.
