Questions people ask
Are rats a bigger problem than mice?
Usually. Rats are bigger, chew more, and avoid new traps for days. They also tend to need more sealing work outside.
Can I just seal the holes myself?
Small gaps, yes. Use steel wool or copper mesh, then seal over it. Foam alone won't stop them. Rooflines and vents are harder, and that's where a pro helps.
How do I know if I have mice or rats?
Check the droppings. Mouse droppings are about the size of a rice grain. Rats also chew larger holes and sound heavier at night.
Are snap traps better than poison?
Indoors, usually yes. Traps let you confirm the catch and remove it. Poisoned rodents can die inside walls and smell for weeks. Bait belongs in locked stations outside.
Is it safe to clean up droppings myself?
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. Never sweep or vacuum them dry.
Are rodent problems in U.S. homes getting worse?
Not noticeably, on the national numbers. About 11.8% of occupied U.S. homes reported rodent signs in the preceding year, based on the U.S. Census Bureau's 2023 American Housing Survey (AHS) counts of 15.7 million out of 133.2 million. Before any work starts in Mishawaka, ask how many visits the price covers and what happens if rodents return.
Are families with kids more likely to have rodents?
