Due to their very successful reproduction, the only way to completely eradicate them is rodent birth control. When you put out poison and traps, for every individual that you kill several more are being born.
Mice have a very strong sense of smell and are often repelled by very strong odors like cinnamon, vinegar, dryer sheets, clove oil, peppermint, tea bags, and cayenne pepper.
Zinc phosphide is an acute toxicant that causes the death of a house mouse within several hours after a lethal dose is ingested. It appears to be the fastest way of getting rid of mice by reducing their population.
The trap that is credited as the first patented lethal mousetrap was a set of spring-loaded, cast-iron jaws dubbed "Royal No. 1". It was patented on 4 November 1879 by James M. Keep of New York, US patent 221,320.
Mice Might Learn to Avoid the Trap in the Area
Although traps are new to them at first, they'll eventually know what it does and find different ways to get the bait while avoiding it. One of the ways that mice do this is to run along walls.
Despite popular belief, mothballs are not an effective solution for deterring mice. While these pesticide products contain strong smelling substances like naphthalene or paradichlorobenzene, their efficacy against rodents is minimal at best.
Signs of an Infestation
A much more likely scenario is that you're already too late. Spotting one elusive mouse typically means there are at least five or six hiding out in your walls, basement, or attic. This is particularly true if you see a mouse at night or in a low-traffic area of your home.
Will Mice Leave If No Food? It all depends, while mice do not just go away on their own, reducing the amount of readily available food that they have access to can help in deterring them from infesting your property.
Best Ways to Get Rid of Mice
Classic snap traps are commonly used to kill mice within homes. For best results, these traps should be set flush to walls, with the trigger plates facing the wall. Glue boards may be effective, as well.
Staff at PaulB Hardware in Lititz, which serves a large agricultural customer base, recommends a product called Fresh Cab. It can repel rodents for up to 3 months, by using a smell that would be extremely offensive to pests, but smells like air freshener to humans.
A dead mouse repels other mice, which is why it's important to get rid of them immediately.
Dry Peanut Butter: If peanut butter dries out and loses its scent, it becomes far less appealing to mice and will mean your peanut butter mouse trap is not working as it should. Over time, exposure to air can cause this beloved bait to become less effective.
Some of the things you can do if the mice in your home are a little too cunning are to study their activity or put less bait on the traps. You may also use baits like peanut butter or change your usual traps. Other ways you can try are getting nesting materials, placing the bait and trap right, or adding more traps.
Mice are actually excellent climbers and can scale any surface that isn't perfectly smooth. This means that they can not only climb within wall cavities and navigate through the entirety of your home but also scale exterior walls in an effort to enter your home through the roof or chimney.
Place a small amount of bait (chunky peanut butter or mutton fat works best) on the bait pan of the snap trap. Place the trap on the floor against the wall. Put the baited end of the trap next to the wall so it forms a "T" with the wall. Rodents prefer to run next to walls or other objects for safety.
But Epsom salt isn't just good for humans! It can also be used to repel rodents due to its acrid smell. Sprinkling Epsom salt onto your trash can lid or around areas where rodents are known to burrow creates a protective boundary that can keep them away.
To discourage mice, remove all food sources by storing grains, pet food, and other dry goods in metal containers. Make sure mice won't find nesting material by storing all soft, fluffy material like fabric, rugs and blankets in heavy plastic or metal boxes.
House mice fall prey to owls, hawks, cats, dogs, skunks and snakes. Barn owls are particularly efficient mice predators. A single family of these owls can consume more than a dozen mice in one night. House mice usually live only one year in the wild due to predators and exposure to unfriendly environments.
