'Tis the good old summertime.  That means bright sunshine, hot days and nights, and insects.  Insects in our homes, our gardens, and our crops.  The presence of insects does not automatically mean control is necessary.

Some insects are beneficial.  Lady beetles and lacewings destroy many aphids each day.  Pest insect populations don't always reach damaging levels even though they feed on the crop.  Control is not profitable under these conditions.  Corn rootworm beetles feeding on silks of corn frequently do not require control.

Sometimes the damage is done before the insects are noticed.  For instance, aphids on the tassels of corn have already damaged the plant.  Aphid control at this stage is not cost effective.

When insects appear on your crops, decide whether control will be economical before spraying.  Being quick on the spray can is important when control is needed, but don't be stampeded into spraying when it's unnecessary.
