Your mother hears scratching after dark. A neighbor finds droppings under the sink. Three pest control companies say they handle mice, but that does not mean they are offering the same job.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
One may plan to place bait and leave. Another may inspect the exterior, close small openings, remove accessible debris, and return to see whether the activity stopped. From five hundred miles away, you need more than a confident phone answer. You need a written route from the first inspection to a house that can be checked again.
Start with the same description of the problem
Give every company the same facts: where signs were found, when someone last saw them, whether food packages are damaged, whether pets live in the house, and whether your mother can safely move items under sinks or near walls. Send the same photos to each company if you have them.
Ask what would change the estimate after arrival. A company that has not seen the basement, attic, attached garage, utility openings, and foundation should tell you what its starting price covers and what would become a separate decision. Do not let a phone estimate quietly become permission for any work the technician finds.
Make the inspection cover the whole route
Ask each provider to name the areas it will inspect. The list may include the kitchen, pantry, basement rim, utility penetrations, doors, garage, attic access, foundation, and the places where pipes or wires enter the house. The exact list depends on the property, but it should be written before the visit.
Then ask what proof you will receive. Useful proof includes labeled photos, a simple floor plan, or a written list showing signs of activity, possible entry points, and places that could not be reached. “Inspected the house” is not enough for you to compare later.
Separate removal from keeping mice out
Ask the company to divide its proposal into three parts: dealing with mice already inside, closing likely entry points, and changing conditions that attract them. A provider may perform all three parts or may refer some work to another trade. You need to know which.
For every proposed repair, ask what material will be used, who will install it, and whether the opening will be photographed before and after. Ask whether door gaps, damaged screens, loose vents, foundation openings, and pipe penetrations are included. A vague promise to “seal where needed” is difficult to verify from another state.
Ask exactly what will be placed in the house
Request the name and type of every trap, bait station, or pesticide the company proposes to use, along with the rooms or exterior areas where each item will go. Ask whether anything will be accessible to your mother, visiting grandchildren, or pets.
The Environmental Protection Agency tells consumers to follow pesticide labels and keep pesticides away from children and pets. Your practical question is simpler: who will explain every placement to the person living in the house, and who will confirm that nothing has been left where she could handle it by mistake?
If pesticide application is proposed, verify the business and applicator through the appropriate Missouri licensing records. Keep the applicator information with the service report. The public agencies and guidance used for this checklist are collected on the Sources page.
Compare the return plan, not the first visit
Ask when the company returns, what it checks, and what counts as continued activity. Find out whether it will inspect traps, refresh bait, remove trapped animals, look for new droppings, or reconsider missed entry points.
Ask who calls if the technician cannot enter, your mother cancels at the door, or a trap needs attention between visits. A monthly service label tells you very little unless the proposal also describes what happens during each visit and how an urgent problem is reported.
Choose the person who will let them in
Do not make your mother carry the entire appointment if she is likely to forget why the company is coming or agree to extra work she does not understand. Choose one local person who can meet the technician, keep your mother away from the work area, and speak with you before approving changes.
Give the company one access plan and one approval number. State in writing who may authorize added work. If no reliable person can attend, arrange local eyes in St. Louis to document the visit and the condition of the house.
Make the final report usable from far away
Before hiring, ask for a sample service report with personal details removed. Look for the technician's name, arrival and departure, rooms inspected, findings, placements, repairs, inaccessible areas, and next step. Ask whether photos can be sent directly to you with your mother's permission.
After each visit, you should be able to answer four questions: What was found? What was done? What remains open? Who checks next? If the company's paperwork cannot answer those questions, you will be managing the problem through scattered phone calls.
Compare every proposal on one page
Put the providers into the same columns: inspection areas, removal method, entry-point work, materials, pesticide placement, pet precautions, number and purpose of return visits, between-visit response, report format, licensing information, access needs, and excluded work.
Choose the company whose plan can be followed and verified, not the company with the shortest description. The best proposal for a distant daughter makes the house, the technician, the local helper, and the next visit visible from the beginning.
What to do tonight
Ask someone nearby to photograph the droppings or damage without sweeping, vacuuming, or handling anything. Have that person note the room, the nearby food or water source, and any gap or opening they can see without moving appliances. Ask your mother to keep pets and food away from the area and not to place loose poison herself.
Send the same short problem description and photos to each provider. Request a written scope that covers inspection, removal, entry points, product placement, follow-up, reporting, and exclusions. Pick the local person who will attend the first visit before you schedule it.
What to leave with the doctor
Do not ask the doctor to choose a pest control company. Tell the office if the proposed visit or preparation would require your mother to lift, climb, move furniture, leave the house, manage traps, or remember special instructions that she may not be able to follow. Ask what limitations the household plan should respect, then give those limits to the provider and the local person attending the visit.
