Rodent control: what to know

What the job involves, what changes the price, and what to ask a pro.

What rodent control is

Rodent control finds how mice or rats get in, sets traps or bait stations, seals entry points and cleans up droppings to reduce rodent activity. People call when they hear scratching in the walls or ceiling, find droppings in the kitchen or garage, or see chewed food packaging and wiring.

Signs you need it

  • Droppings appear in the pantry, under the sink, in the garage or along the wall behind appliances
  • Scratching, scurrying or gnawing sounds come from the walls, attic or crawl space, mostly at night
  • Food packages, cereal boxes or pet food bags have holes chewed through them
  • Greasy rub marks appear along baseboards, pipes or the edges of cabinets where rodents travel
  • Wires, insulation or nesting material have been chewed or pulled into a hidden space

What the pro does

  • The technician walks the interior and exterior to find droppings, rub marks, nesting sites and the likely entry points
  • Entry points are located, measured and marked, including gaps around pipes, vents, doors and the foundation
  • Traps or bait stations are placed along the travel routes, with bait kept in tamper-resistant stations away from children and pets
  • Entry points are sealed with steel wool, metal mesh and sealant, since rodents can chew through soft materials
  • The technician checks the traps, removes what is caught and explains the sanitation steps for droppings and food storage

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Species involved, since mice and rats differ in size, behavior and entry needs
  • Number of entry points and how hard they are to reach
  • Severity of the activity and how long it has been going on
  • Amount of sealing and exclusion work needed around the structure
  • Access to attics, crawl spaces, wall voids and garages
  • Number of visits needed to check traps and confirm the activity has stopped
  • Cleanup of droppings, nesting material and contaminated areas

What a written quote should spell out

  • The species identified and the signs found, with the locations listed
  • The number of traps and bait stations placed, and where each one is
  • The entry points found, the sealing method and the materials used
  • The sanitation steps for droppings and nesting material, with the safety method used
  • The follow-up visits and what happens if activity continues
  • What you must do afterward, such as keeping food sealed and clearing clutter

Questions to ask before you hire

  • What species do you think it is, and how did you identify it?
  • How do you find the entry points, and what do you seal them with?
  • Are the bait stations locked, and how do you keep them away from pets and children?
  • How do you clean the droppings and nesting material safely?
  • How many visits will you make, and what do you check on each one?
  • What happens if the rodents come back after the sealing is done?
  • Will you check the attic and crawl space as well as the living areas?

Red flags

  • They put bait out in open areas where children and pets can reach it
  • They seal entry points without first finding the rodents or the routes they use
  • They clean droppings by sweeping or vacuuming them dry, which can spread dust
  • They promise the rodents will be gone after one visit with no follow-up
  • They will not say what the bait or traps contain or where they are placed

What you can do yourself

A homeowner can seal small gaps with steel wool, metal mesh and caulk, and set snap traps or enclosed traps with care. When cleaning droppings, wear gloves and a mask, spray them with a disinfectant or wet them first, and do not sweep or vacuum them dry. Call a licensed pest control operator for large or spreading infestations, for activity inside walls or in attics, and for any use of rodenticide, since bait can harm children, pets and wildlife.

Licenses and permits

Rodent control using pesticides or rodenticides for pay is commonly licensed in many areas; trapping and exclusion may fall under separate rules, and some wildlife may be protected. Check with your state or local licensing agency before you hire or offer the service.

Rodent control questions

Why are mice and rats a concern inside a house?

Both can damage food, wiring and insulation, and both can carry disease. Their droppings and nests are the main hazard during cleanup. A licensed operator can identify the species and recommend the right plan for it.

Is it safe to clean up droppings myself?

Yes, with care. Wear gloves and a mask, wet the droppings with disinfectant, wait a few minutes, then pick them up with paper towels and bag them. Do not sweep or vacuum them dry, and wash your hands afterward. For heavy droppings, nests, or enclosed attics and crawl spaces, have a professional do the cleanup with proper protective gear.

Why do rodents keep coming back after I set traps?

Usually the entry point is still open, or the food and nesting sources are still there. Seal the entry points and tighten up food storage, and ask the operator to check the exclusion work.
