Exterminators do not guarantee permanent removal of mice by simply treating a current infestation. While professional exterminators are very effective at getting rid of mice present at the time of treatment, mice can return if conditions that attracted them — food, water, and entry points — are not fixed.

The Key Distinction: Trapping vs. Exclusion

The difference between temporary and permanent results comes down to whether the exterminator also performs exclusion — physically sealing the entry points mice use. Trap-only treatments eliminate current individuals but cannot stop new ones from entering. Ask your exterminator explicitly: do you seal entry points?

• Trapping only = temporary. Removes current mice, leaves entry points open.
• Exclusion treatment = near-permanent. Seals all entry points and removes current infestation together.

How Exterminators Remove Mice

Professionals inspect the property, set traps in optimal locations, use baits where appropriate, remove dead mice, and clean nests. These steps are far more effective than store-bought traps placed without a full inspection. However, this only addresses mice already inside.

Why Mice Keep Returning

Mice can squeeze into gaps as small as a pencil's width (about 6mm). If no action is taken to block entry points and remove food and shelter, more mice will move in over time.

How to Make Mice Removal Permanent

• Seal all entry points with steel wool, metal mesh, caulk, or metal flashing
• Store all food in airtight containers
• Remove clutter and nesting materials
• Trim vegetation away from the building
• Fix water leaks
• Schedule follow-up monitoring visits

Questions to Ask Your Exterminator

• Do you seal entry points, or just trap?
• Do you offer a service guarantee?
• Are your products safe around children and pets?
• What ongoing prevention plan do you recommend?
