How do I know if I have mice or rats?
Droppings, urine stains and gnaw marks are the most reliable signs. A sighting in daylight can mean the population is larger than it looks.
Rodents are mostly active at night, so most people find the evidence before they see the animal. Droppings tend to collect along walls and near the places where the animals feed, and their size helps tell a mouse from a rat, a point a technician will check on site.
A flashlight run along the baseboards, behind the stove and under the sink often shows the trail. Urine stains fluoresce under ultraviolet light, which is one way a technician finds old runs that are no longer obvious.
How does a technician get rid of them?
The technician places traps or bait stations on the runs the animals use, checks them on each visit, and removes captures and dead animals as the work goes on.
Snap traps are set square to the wall, because rodents tend to travel along edges rather than cross open floor. Bait stations are enclosed so the bait is not left loose, and they are placed and labelled as the product requires.
The technician will say what is being placed and where before work begins. Traps and stations are checked on each visit, since a sprung trap or an emptied station is the clearest sign of how the work is going.
Why do mice come back after the first visit?
The animals are rarely the whole problem. Repeat activity usually traces back to an opening that was never closed, or to food and nesting material left within reach.
Rodents can squeeze through openings much smaller than most people expect, and they can gnaw through soft materials such as weatherstripping, foam and thin wood. A gap that looks too small to matter can be the route that keeps a house supplied.
Feed kept in paper or cloth bags, a pet food dish left out overnight and stored boxes in the basement all give rodents a reason to stay. The technician checks these with the homeowner on the first visit.
What about bait around pets and children?
Bait placement is decided on site, because it depends on the building, the animals and the people who use it. Ask what is being placed, where, and how it is kept out of reach.
Rodent bait is a pesticide, and its label sets the rules for where it can go and how it must be contained. Enclosed stations fixed in place are the usual way to keep bait away from a dog or a child who explores.
If working animals or livestock share the building, the technician plans the placement around them and does not put loose bait where stock can reach it.
What moves the price up or down?
The size of the house and outbuildings, the number of rooms and buildings involved, how hard the runs are to reach and how many visits the job takes all change the price. The technician explains it on site, and it is approved before work starts.
A single house with one visible problem is a short job. A farmstead with several outbuildings, a crawl space, feed storage and a barn that needs exclusion is a longer one, and that difference shows up in the number of visits and the time spent on each.
Access matters too. A basement behind stored items, a crawl space with a small hatch and an attic with loose insulation all take more time. The price is set after the inspection, and no work starts until the homeowner has seen it and agreed to it.
