General Pest Control Terms
Exclusion
The process of physically sealing the entry points animals or insects use to get into a building, rather than just treating what's already inside.
IPM (Integrated Pest Management)
An ongoing, multi-part approach to pest control that combines inspection, prevention, and targeted treatment, rather than relying on a single spray visit.
Harborage
A hiding spot pests use for shelter — typically dark, undisturbed areas like wall voids, under appliances, or cluttered storage spaces.
Bait Station
A protected container holding pest bait, placed in strategic locations to attract and eliminate pests like ants, roaches, or rodents at the source.
Perimeter Treatment
Pest control treatment applied around the exterior of a building — foundation, entry points, and surrounding vegetation — rather than inside the home.
Barrier Treatment
A treatment applied to vegetation and resting areas in a yard, most commonly for mosquitoes, that creates a protective zone rather than targeting individual insects.
Ant & Insect Specific Terms
Carpenter Ants
A larger ant species that excavates (rather than eats) wood to build nests, which can indicate existing moisture damage and cause further structural harm over time.
Odorous House Ants
A small, dark, common household ant that releases a rotten-coconut smell when crushed — mostly a nuisance pest, not a structural concern.
Camel Crickets
A humpbacked, jumping cricket species that doesn't chirp and is commonly found in damp basements, crawlspaces, and garages.
Frass
Fine, sawdust-like debris left behind by wood-boring insects such as carpenter ants or wood-destroying beetles, often found near an active nest.
Egg Sac
A silk case spiders spin to protect their eggs, often found in undisturbed corners, garages, or window wells.
Termite & Structural Terms
WDI Inspection
A Wood-Destroying Insect inspection that checks a property for current or past termite (or similar) activity — commonly required within 90 days of a Virginia home sale closing.
Mud Tubes
Narrow tunnels made of soil and saliva that subterranean termites build to travel between the ground and a food source while staying protected from open air.
Subterranean Termites
The most common termite species in Virginia, living in underground colonies and needing contact with soil moisture to survive, distinct from drywood termite species.
Flea & Tick Terms
Licensing & Regulation
Commercial & Business Terms
Certificate of Insurance (COI)
A document confirming a business's liability insurance coverage, often required by commercial clients before service begins and naming the client as “additional insured.”
Service Log
A signed record left on-site at every commercial pest control visit, documenting areas serviced, products used, and any findings — often required for health inspections.
Net-30
A billing term meaning payment is due within 30 days of the invoice date — standard for commercial accounts rather than pay-at-time-of-service.
