Acetamiprid is a common pesticide used on fruit trees. A broad-spectrum insect killer, it kills more than 100 hundred species of insects. It protects trees for up to three weeks inbetween applications. The pesticide is mixed with water and is applied to the tree. Exact application depends on various manufacturers; some companies make a special applicator to fit the bottle while others require manual mixing and application. Follow the directions on the label for application. Acetamiprid can be found at home improvement stores and gardening centres.

BT–bacillus thuringiensis–is an organic pesticide. Mimicking the chemicals found in the stomach of certain moths, the compound kills common fruit tree pests. Safe for mammals and non-target species, BT is popular in home gardens because it is safe for children and pets. Bacillus thuringiensis can be purchased at speciality garden centres. BT in pure form comes in a powder; it often is mixed with water or another liquid agent for easier application on plants. Exact application varies depending on the manufacturer, so follow label directions.

Exposure to high doses of malathion can affect the nervous system, according to the Cornell University Cooperative Extension website. This chemical should be kept away from pets and children. Malathion pesticides are found at speciality garden centres.
