Often, the insects you see in the yard are not harmful and may even be beneficial. To manage possible pests; the first rule is identification. Then determine what level of damage is acceptable to you. If that threshold is passed, use the least toxic method of control. Hand removal is a good option if there are only a few insects or they are grouped together. Remember, pesticides should be used as a last resort, they will kill good bugs like this Margined Soldier Beetle a.k.a. Margined Leatherwing (Chauliognathus marginatus) on fleabane (Erigeron spp). This adult Soldier Beetle mainly gathers pollen, but the larvae eat aphids, caterpillars, grasshopper eggs and other soft bodied insects.
