Questions people ask
Will rodent control harm my pets?
Bait stations are locked. Tell the company about your pets before they start. It shouldn't. Traps go where pets can't reach.
What is rodent-proofing and why does it cost so much?
A mouse fits through a dime-sized gap, so it's slow work. It's also the part that keeps them out. It means sealing every gap with metal mesh and sealant.
Do I need to replace attic insulation?
Light activity can often be cleaned up. Ask the inspector to show you before you agree to replacement. Only if it's heavily soiled or flattened by nesting.
How do I choose a rodent control company?
Ask what happens if rodents come back. A good company talks about sealing, not just traps. Make sure they're licensed in Tennessee. Ask how they seal gaps and what materials they use.
Are snap traps better than poison?
Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside. Indoors, usually yes. Traps let you confirm the catch and remove it.
Do homes with rodents usually have other pests too?
The U.S. Census Bureau's 2019 American Housing Survey (AHS) counted 2.9 million occupied homes that had seen both rodents and cockroaches in the preceding year. Often enough to matter.
Are families with kids more likely to have rodents?
