Pest Control Terms in Plain Words for Detroit Homeowners
The words you might hear on a visit or read on an estimate, without the jargon.
Pest control comes with its own vocabulary, and some of it sounds worse than it is. Words like “residual”, “infestation” and “harborage” turn up on estimates and in conversation on a visit, and none of them should be a mystery. Each term gets a plain meaning and the service you’re most likely to hear it with.

Pest Control Terms From A to Z
Bait Station
A closed box that holds bait inside, out of the weather, with openings sized for the pest. Outdoor rodent stations are usually locked and anchored along the foundation.
Related: Rodent Control
Colony
The whole population of a social insect, such as ants or wasps, living and working around one or more queens. Dealing with the colony, not just the insects you see, is what ends the problem.
Related: Cockroach and Ant Control
Crack-and-Crevice Treatment
Placing a small amount of product right into the gaps where insects hide, such as behind baseboards, under counters and around pipes, instead of spraying open surfaces.
Related: Cockroach and Ant Control
Dormant Season
The cold months when many outdoor insects stop breeding and wait out the winter as eggs, larvae or resting adults. Indoor pests like roaches and mice don’t take the winter off.
Related: Seasonal Tips
Dust
An insecticide made as a fine powder and puffed into wall voids, behind outlet covers and into other dry, hidden spaces. Dusts can keep working for months where they stay dry and undisturbed.
Related: Cockroach and Ant Control
Egg Case (Ootheca)
The purse-shaped capsule a female cockroach makes to hold her eggs. A German cockroach carries hers until the eggs are nearly ready to hatch, one reason roaches come back after a spray alone.
Related: Cockroach and Ant Control
Entry Point
Any opening a pest uses to get inside: a gap under a door, a crack in the foundation, a torn vent screen or the seam where siding meets the foundation.
Related: Rodent Control
Exclusion
Sealing the openings pests use to get in, with materials they can’t chew through, such as metal mesh, hardware cloth, sealant and door sweeps. It’s the part of rodent work aimed at keeping new ones out.
Related: Rodent Control
Follow-Up Visit
A return visit to check traps, baits or monitors and see whether activity has dropped. Cockroach and bed bug work usually needs at least one, because eggs can hatch after the first treatment.
Related: What to Expect
Frass
Insect droppings and the debris insects leave behind: dark specks from cockroaches and bed bugs, or sawdust-like piles from carpenter ants pushing wood out of their tunnels.
Related: Cockroach and Ant Control
Gel Bait
A bait in paste form, placed in small dots where roaches or ants travel. The insects eat it and carry it back to where they hide, reaching others nobody can see.
Related: Cockroach and Ant Control
Harborage
A place where pests hide, rest and breed: a gap behind a cabinet, a pile of cardboard, a wall void. The British spelling is harbourage. Cutting down harborage helps any treatment work.
Related: Cockroach and Ant Control
Hardware Cloth
A stiff metal mesh with small square openings, used to cover vents, gaps under porches and other openings rodents would chew through. Air gets through it; mice don’t.
Related: Rodent Control
Infestation
Pests living and breeding in a place rather than just passing through. The word describes how settled the problem is, not how clean the home is.
Related: Signs and Symptoms
Insect Growth Regulator (IGR)
A product that stops young insects from growing into breeding adults instead of killing them on contact. It’s often paired with a bait or a spray to break the breeding cycle of roaches.
Related: Cockroach and Ant Control
Inspection
The careful look before any treatment: checking for droppings, damage, nests, harborage and the way pests are getting in. What turns up decides what the treatment should be.
Related: What to Expect
Instar
One stage of an insect’s growth between molts. Young bed bugs pass through five instars before adulthood, shedding a skin each time, which is why pale shed skins are a common sign.
Related: Bed Bug Treatment
IPM (Integrated Pest Management)
An approach that starts with inspection and prevention, such as sealing gaps and fixing leaks, and uses products only where and when they’re needed. Most modern pest control follows it.
Related: Services
Label
The printed directions on a pesticide container. In the US the label is the law: it sets where a product may be used, how much, and how long people and pets should stay out of a treated area.
Related: Services
Larva
The grub-like young stage of insects such as wasps, flies and beetles, which looks nothing like the adult. Wasp larvae stay in the nest cells and are fed by the workers.
Related: Wasp and Hornet Removal
Monitoring Station
A sticky card or small station set out to show whether pests are present and how many, not to control them. Monitors are how anyone can tell whether a treatment is working.
Related: Cockroach and Ant Control
Nymph
A young insect that looks like a small, pale version of the adult, as young bed bugs and cockroaches do. Nymphs feed and molt several times before they can breed.
Related: Bed Bug Treatment
Perimeter Treatment
A band of product applied around the outside of a building, along the foundation and around doors and windows, to stop crawling insects before they get in.
Related: Cockroach and Ant Control
Queen
The egg-laying female of an ant, wasp or hornet colony. Wasp queens spend the winter alone and start new nests in spring; an ant queen usually stays deep in the nest, out of sight.
Related: Wasp and Hornet Removal
Residual Treatment
A treatment that keeps working for a while after it’s applied, from days to weeks depending on the product and the surface. It breaks down over time rather than lasting forever.
Related: Cockroach and Ant Control
Rub Marks
Dark, greasy smudges along walls, beams and pipes where mice or rats brush the same path night after night. Fresh marks smear when touched; old ones are dry and dull.
Related: Rodent Control
Satellite Nest
A smaller nest an ant colony sets up away from the main one, often indoors near warmth and moisture. It’s why ants can keep showing up after the nest outside is dealt with.
Related: Cockroach and Ant Control
Snap Trap
The classic spring trap for mice and rats, set along walls where rodents travel. Traps are usually set in groups and checked often, in the kitchen, the basement or the garage.
Related: Rodent Control
Swarmer
A winged ant or termite that leaves its colony to mate and start a new one, mostly in spring. Swarmers indoors usually mean a nest inside the walls or under the floor nearby.
Related: Cockroach and Ant Control
Wall Void
The hollow space inside a wall. Mice travel through it, yellowjackets and wasps nest in it, and treatments often reach it through outlet boxes or small drilled holes.
Related: Wasp and Hornet Removal
If you’ve already found frass, rub marks or an egg case at home, comparing it with the other signs of pests helps narrow down which pest it is and how soon it needs attention.
Words That Sound Worse Than They Are
Does “residual” mean the product stays in my home for good?
No. Residual only means a treatment keeps working for a while after it’s applied, usually days to weeks depending on the product and the surface it’s on. It breaks down over time, and indoors it normally goes into cracks and along baseboards rather than across open floors and counters.
If you want to know how long a particular treatment lasts, or how long to keep kids and pets out of a room, ask. The product’s label sets those rules.
Why does a pesticide label carry so many warnings?
Every registered pesticide in the US has to carry a label, and the label is the law for how it’s used. The signal word on the front, “Caution”, “Warning” or “Danger”, describes the concentrated product in the container, and the directions say where it can go and how long to stay out of a treated area.
The warnings are standard on every product, from a hardware-store ant bait to the products professionals use. Reading the label, or asking what it says, is always reasonable.
Does “infestation” mean my home is dirty?
No. It just means pests are living and breeding in a place rather than passing through. Bed bugs arrive in luggage and secondhand furniture, mice come in through gaps in the foundation, and roaches move between apartments through shared walls. Very clean homes get all three.
Clutter and food left out can make a problem worse, and tidying up helps any treatment work, but the word itself says nothing about housekeeping.
Is a “treatment” the same as spraying the whole house?
Rarely, these days. Most indoor work uses gel baits, dusts in wall voids and crack-and-crevice treatment, placed where the pests hide, and a perimeter treatment outside along the foundation. Spraying every room is uncommon and usually not the most effective approach.
