Martinsburg's wooded ridges and creek corridors produce robust yellowjacket and hornet populations that peak in August and September — precisely when outdoor activity is highest. We safely eliminate nests and reduce the risk before anyone gets hurt.
The Eastern Panhandle's climate — warm, humid summers moderated by the Blue Ridge — creates an extended stinging insect season that catches many Martinsburg homeowners off guard. Colonies that started from a single queen in April grow steadily through June and July, then reach peak population and aggression in August and September, when natural food sources start declining and the colony shifts to defending its nest more aggressively.
Yellowjackets are the most dangerous stinging insect in Berkeley County by injury statistics. They build in wall voids, in the ground alongside foundations, beneath deck boards, and in any undisturbed cavity that offers shelter. Unlike paper wasps, yellowjackets will pursue a perceived threat for a significant distance and sting repeatedly — a colony disturbed during fall cleanup can produce a genuinely dangerous defensive response.
Bald-faced hornets build the large, papery gray nests that appear in tree branches, on eaves, and against siding throughout Martinsburg's tree-rich residential areas. Their nests become truly large by late summer — 10–14 inches across is not unusual — and like yellowjackets, they defend aggressively when approached. These nests are frequently discovered during fall tree trimming or gutter cleaning, when the colony's presence isn't suspected until the equipment disturbs the nest.
Paper wasps build the familiar umbrella-shaped open-cell nests under eaves, deck railings, window frames, and any protected horizontal surface. They're less aggressive than yellowjackets but will sting if the nest is bumped or approached closely. Multiple nests under the same eave are common, and they consistently reuse the same locations year after year.
The treatment approach for a paper wasp nest under an open eave is completely different from treatment for a yellowjacket colony in a wall void or a ground nest in the lawn. We identify what you're dealing with and where the nest is — including using flight pattern observation to locate nests that aren't visually obvious — before applying any treatment.
Wall void nests are the most dangerous and the most commonly handled incorrectly. Spraying at the entrance drives wasps deeper into the void and can force them into the living space through wall voids. We treat with dust insecticide applied directly into the nest cavity — a method that reaches the colony interior while containing the treatment and preventing indoor emergence.
Ground nests are treated at dusk or early morning when forager wasps have returned to the colony and activity is minimal. This timing dramatically reduces the number of flying workers present during treatment and produces complete colony elimination rather than leaving a significant portion of the population outside the treatment zone.

Yellowjacket colonies in the Eastern Panhandle reach maximum population — often 3,000–5,000 workers — in late August and September. At the same time, their natural insect prey starts declining as summer ends, driving the colony toward scavenging and increasing the defensive aggression that produces stinging incidents. A colony that coexisted peacefully with human activity all summer becomes genuinely dangerous in fall.
More stinging insect injuries in Martinsburg occur during September and October fall cleanup activities than during any other time of year. Raking near ground nests, moving woodpiles that harbor yellowjackets, trimming vegetation near hornet nests, and cleaning gutters where paper wasps nest are all activities that regularly produce encounters with colonies that have been present — and growing — all summer without being detected.
Martinsburg's proximity to the forested ridges on either side of the valley means that bald-faced hornet and yellowjacket pressure from wooded habitat is persistent throughout the summer. Properties near North Mountain, Sleepy Creek Mountain, and the forested areas along the creek drainages see higher stinging insect pressure than properties in the valley floor, and benefit from earlier-season awareness and treatment.
Dust insecticide treatment directly into wall void and ground nest entrances — reaching the colony interior without driving workers into the living space.
Targeted treatment of arboreal and structural hornet nests followed by physical removal where accessible — preventing nest reuse in subsequent seasons.
Treatment and physical removal of paper wasp nests from eaves, railings, and window frames before late-summer colonies reach maximum size and defensive behavior peaks.
After colony elimination, sealing the entry void prevents the same location from being reused by new queens the following season — particularly important for wall voids and soffit gaps.
A nest found in June is manageable. The same nest in September holds thousands of workers. Call the Martinsburg Pest Control Team now and don't wait for an incident to make you call.
