Delaware pest control: common pests, seasons & local options
From the Rehoboth Beach Boardwalk to the Brandywine Valley, the First State's small size belies its pest pressure. Wilmington, Dover, Newark, and Middletown homeowners face heavy termite activity, marsh-bred mosquitoes, spring ants, and ticks in one of America's most densely settled small states.

Ants
Odorous house ants and carpenter ants invade Delaware kitchens every spring and summer.
Ticks
Blacklegged ticks thrive in Delaware's parks and wooded suburbs from spring through fall.
