Aphid insecticides are used to kill soft-bodied insects, such as potato bugs. The insecticides are often sprayed on plants or vegetables to protect crops.
Untreated aphid infestations can lead to plant and tree damage. This occurs because aphids inject saliva into leaves, which can cause them to wilt or become discolored.
In order for insecticides to be productive, they must come into contact directly with the insects. Insecticides differ and some are safer for vegetation than others. Some are also made for specific types of insects. Insecticides should only be used after the users follows the directions carefully for safety reasons.
