What shapes pest pressure in Claymont

Claymont sits in the northeast corner of New Castle County, where Naamans Creek discharges into the Delaware River. The creek’s north branch drains land west of Marcus Hook, Pennsylvania, and its south branch drains residential and commercial areas of northern New Castle County, according to a DNREC watershed analysis. A state historical marker on Naamans Road identifies the Block House as the only house remaining from the original settlement on Naaman’s Creek. Nearby, Fox Point State Park sits on the banks of the Delaware River, with views of Pennsylvania to the north and New Jersey to the east.

For pests, northern New Castle County has a few things worth knowing. Spotted lanternfly was first detected in New Castle County, and the Delaware Department of Agriculture now has the entire state under quarantine. DNREC reports longhorned ticks in New Castle and Kent counties in spring and summer, and blacklegged ticks live in wooded areas and forest edges statewide. Creek corridors, low wet spots and backyard containers give mosquitoes places to breed, and mice and stink bugs look for a way indoors as fall nights cool.

Pest season in Claymont

Spring
Spotted lanternfly nymphs hatch; the Department of Agriculture asks residents to destroy them. Longhorned ticks become active.
Summer
Adult spotted lanternflies appear on trees and decks, and mosquitoes breed in standing water. Check for ticks after time near the creek or woods.
Fall
Spotted lanternflies lay egg masses on trees, stone and outdoor items — scrape and destroy them. Mice and stink bugs head indoors.
Winter
Rodents stay in walls and basements. DNREC says blacklegged tick adults are most active in the late fall and winter.
