- Where are they getting in? - Which gaps will you seal, and with what? - How many trap visits are included? - What happens if they come back? - Is cleanup included, or extra? - Will you use poison inside? (Ask them not to.)

Questions people ask
What should be in a rodent control quote?
It should say what happens if they return. Cleanup should be listed separately. Entry points, sealing materials and the number of trap visits.
Why do rodents keep coming back every year?
Traps remove the rodents inside. New ones follow the same path in. Usually because the entry points were never sealed.
Can I just seal the holes myself?
Foam alone won't stop them. Rooflines and vents are harder, and that's where a pro helps. Small gaps, yes. Use steel wool or copper mesh, then seal over it.
Is it safe to clean up droppings myself?
Never sweep or vacuum them dry. Deer mice here can carry hantavirus. Take extra care in sheds. For small amounts, yes, with care. Wear gloves and spray the droppings with a bleach solution. Wait five minutes, then wipe up with paper towels.
How do I choose a rodent control company?
