Through this article we’ll go over important facts that you need to know about how to get rid of deer mouse infestations. Integrating many strategies is necessary for effective management. Infestations can be avoided by taking steps including habitat alteration, sanitation, and exclusion. It is nearly always required to reduce the population of mice when they are already an infestation by catching them and/or using poisonous bait. Following successful deer mice population management, it’s critical to keep an eye out for any indications of a infestation. Watch for any indications of fresh action. While the distinctive musky smell of house mouse infestations is prevalent, activity signs resemble those of any mouse typically.
Exclusion
The most efficient and long-lasting way to guarantee the absence of deer mice and other rodent infestations in structures is to utilize rodent-proof construction to keep deer mice out of homes, apartments, and other buildings. Openings bigger than 1/4 inch should be sealed since mice will nibble on them to make them bigger. A excellent temporary stopper is steel wool. Mouse holes shouldn’t be sealed with plastic screens, rubber, vinyl, insulating foam, wood, or other items that mice can nibble through.
Use metal or concrete to fill up cracks around water pipes, vents, and utility cable openings as well as in the foundations of buildings. Entryways to garages, attics, crawl spaces, and basements should fit snugly. Other items to consider include pet doors, windows, ventilation screens, and doors and door screens. Edge protection may be required. of doors and windows with metal to prevent gnawing
Replace any doors, windows, vents, or screens that are irreparably broken. Install spark arresters in chimneys to help deter intrusion. On outdoor dryer vents, self-closing flaps can keep rodents out. When cleaning dryer vents, be careful because an accumulation of dryer lint might result in fires. When deer mice and other rodents are most active at night and through the day, keep the side doors to the garage closed.
Habitat Modification
Gardens and yards can be modified to make them less inviting for deer mice. Deer mice’s cover and potential havens can be drastically reduced by cutting back on overgrown weeds, hedges, and shrubs. In order to prevent deer mice from nesting in homes and other buildings, wood and brush piles, as well as downed trees, should be kept away from these structures. Deer mice may enter these structures through these openings. As a deer mouse’s home range ranges from 1/3 acre to 4 or more acres, habitat modification can help reduce the number of deer mice in a region but won’t totally eradicate them.
Trapping and Glue Boards
Deer mice spotted in or around buildings can be captured using snap traps and electrocution traps. An excellent attractant is typically peanut butter or peanut butter combined with cereal or rolled oats. To quickly and successfully regulate a huge population, you might require a dozen traps or more. After the first control period, it’s crucial to have some traps in place to stop reinvasion or a revival of the deer mouse population.
Placement of the trap is crucial. Place traps no more than 10 feet apart in locations where there are indications of activity in order to enhance capture success. Mice often run along walls, therefore if traps are set with the trigger pointing at the intersection of a wall and the floor then the mouse will run directly across the trigger and very likely be caught.
Take care to avoid potential hantavirus exposure when trapping. When removing traps, resetting used and older traps, or getting rid of dead mice, put on rubber, latex, vinyl, or nitrile gloves. Apply a thorough disinfection solution to all contaminated locations, including deer mice trapped, their droppings, and nests. Although there are various commercially available multiple-catch mouse traps that can catch deer mice, using these traps isn’t advised due to the increased risk of hantavirus exposure. Live-capture traps bring the additional issue that the trapped mice must be humanely put to death, and they very soon become polluted with mouse feces and urine.
Commercial glue boards are offered for the purpose of reducing mouse and rat populations. When mice are trapped on adhesive boards, they frequently urinate and feces while trying to release themselves from the glue. This method of deer mouse collection dramatically increases the risk of hantavirus exposure. Glue boards should not be used to control deer mice.
Biological Control
Many predatory animals, birds, and reptiles prefer to feed on deer mice and other Peromyscus species. Many deer mice can be eaten by snakes, owls, weasels, skunks, badgers, foxes, coyotes, and bobcats all at once. However, in most cases, such natural predation is insufficient to keep deer mouse populations under control to a point where they cannot cause harm or provide a risk of hantavirus exposure.
Deer mice can be caught and killed by dogs and cats. However, it is unlikely that they will successfully control deer mouse populations, necessitating the deployment of alternative control strategies. Upon reduction or eradication of deer mouse populations, cats may be able to prevent reinfestation. However, mice frequently coexist in close proximity with cats and dogs in metropolitan areas. Some rats also find sanctuary in dog homes, sheds, and other types of cover in residential settings, and spills from bird feeders and pet food bowls frequently contribute to rodent infestations.
Toxicants (Rodenticides)
In many cases, toxic bait (rodenticides) can be a useful part of an IPM program for managing deer mice populations when their numbers have gotten rather high. According to the active ingredient, rodenticides can be categorized into three categories:
- First-generation anticoagulants: warfarin, chlorophacinone, and diphacinone (only the second two are registered for use against deer mice);
- Second-generation anticoagulants: brodifacoum, bromadiolone, difenacoum, and difethialone (none of which is registered for use against deer mice); and
- Nonanticoagulants: bromethalin, cholecalciferol, and zinc phosphide (the latter being the only one registered for use against deer mice).
When employed as active components in rodenticides, anticoagulants inhibit blood from clotting and result in internal bleeding, which kills rodents. First-generation anticoagulants are less likely to harm pets and unintended wildlife than the majority of other rodenticides since they typically require many feedings spread out over several days to reach a lethal dose.
Second-generation anticoagulants are significantly more toxic than first-generation anticoagulants but have the same mode of action. After just one meal, they are lethal in several species. Anticoagulants may remain in the target animal’s tissues even after death. Second-generation anticoagulants are not approved for use against deer mice since they are extremely toxic and remain active for a longer period of time in animal tissues.
The only nonanticoagulant rodenticide approved for use against deer mice is zinc phosphide. In the mouse’s stomach, zinc phosphide consumption results in the production of phosphine gas. All animals are fatally affected by phosphine gas, which results in death after just one feeding.
Pets, household animals, and wildlife can all be poisoned by rodenticides either by eating toxic bait directly (primary exposure) or by eating dead or dying rats that have eaten toxic bait (secondary exposure). Follow the label instructions and take precautions to avoid unintentional poisonings when using any rodenticide. These dangers can be decreased by using only tamper-resistant bait stations for bait exposure and by finding and properly discarding the carcasses of poisoned rats.

Controlling deer mice in residential settings
While poisonous baits have been licensed for the management of deer mice in domestic settings, rodenticides are still readily accessible for retail purchase to control house mice and rats. Use of rodent baits marked “only against house mice, Norway rats, and roof rats” in an effort to manage deer mice is against the terms of the product label. Instead, traps, exclusion of mice from structures, and habitat modification to remove sources of food and shelter should be used to control deer mice in homes.
Consider contacting a professional certified Franklin pest control exterminator with experience in rodent control if the deer mouse infestation is fairly extensive and applying effective control looks like an overwhelming effort. Are deer mice dangerous? Keep reading to find out more.
