Delaware service areas

Based in Newark, DE and licensed to treat homes and businesses statewide - New Castle, Kent and Sussex County.

New Castle County

Our home base. Newark, Bear, Glasgow and Wilmington properties usually get same-week appointments, and older row homes and student rentals get roach, rodent and bed bug work year-round.

Kent County

Dover-area homes, farms and rentals see heavy ant, spider and rodent pressure in the fall. We run scheduled Kent County routes so quarterly plans stay on time.

Sussex County

Beach rentals, second homes and coastal construction bring mosquitoes, ticks, ants and stinging insects. We handle turnover inspections between rental weeks.
