Mosquito barrier rounds
Roughly May through September, on a rotation set by how fast the product breaks down rather than by the calendar.
Tick treatment
Two pressure peaks in eastern Nebraska: late spring for nymphs and early fall for adults.
Perimeter treatment
Spring as things wake up and come in, fall as they look for somewhere warm to overwinter.
Wasp and hornet work
Colonies are largest and most defensive from midsummer, which is also when people find them.
Grub protection
Applied before the damage rather than after it. Curative treatment in September is a much worse deal.
Event spraying
Booked to your date, applied a day or two ahead. Any warm month, on request.
