Core Pest Control Terms
The essential words, defined simply.
Integrated Pest Management
IPM: a method using inspection, prevention, and targeted treatment to control pests with the least product needed.
Barrier Treatment
A protective perimeter applied around a home's exterior to stop pests before they get inside.
Residual
How long a product keeps working after it is applied. A longer residual means longer-lasting protection.
Bait
A product pests eat and carry back to the nest, reaching the colony and the queen at the source.
Exclusion
Sealing gaps, cracks, and entry points so pests cannot get into your home in the first place.
Infestation
An established pest population large enough to require active treatment, not just a stray bug or two.

Glossary FAQs
- Knowing the language helps you compare quotes, ask better questions, and understand exactly what a company will do. It also helps you spot vague or misleading claims, so you can choose a provider you trust.
- Bait is a product pests eat and carry back to the nest, reaching the colony at its source. A barrier is a protective perimeter treatment around the home's exterior that stops pests before they get inside.
- Residual describes how long a product keeps working after it is applied. A longer residual means longer-lasting protection between visits, which is why professional treatments often outperform quick store-bought sprays.
- Integrated pest management, or IPM, combines inspection, prevention, exclusion, and targeted treatment to control pests with the least product needed. It focuses on solving the root cause rather than repeatedly spraying surfaces.
- An infestation is an established pest population large enough to need active treatment. A stray spider is not an infestation, but repeat sightings, droppings, or a visible nest usually mean a real problem that needs a pro.
- Exclusion means sealing the gaps, cracks, and entry points pests use to get into your home. It is a key prevention step, since keeping pests out is easier and cheaper than removing them once they are inside.
