It has flu like symptoms that can last for days and is sometimes fatal. Leptospirosis, Lymphocytic choriomeningitis, trichinosis, typhoid, dysentery as well as others. Rats and mice almost always leave signs that can lead to their discovery. Most over the counter baits sold at hardware stores and retailers do not contain the same attractants or active ingredients as professional use baits. Although the packaging and advertising may appear convincing, millions of dollars are wasted by consumers annually on over the counter rodent bait products that simply do not work. Professional Quality rat and mouse control and bait products at the lowest possible price.
There are 3 main species of rats and mice that are of significance in the United States. 2 ounce and usually are light brownish to gray in color. An adult is about 5 to 7 inches long, including the 3- to 4-inch tail. Droppings, fresh gnaw marks, and tracks indicate areas where mice are active. Mouse nests are made from fine shredded paper or other fibrous material, usually in sheltered locations. House mice have a characteristic musky odor that identifies their presence.
Mice are active mostly at night, but they can be seen occasionally during daylight hours. While the house mouse has not been found to be a carrier of hantavirus, other mice have. Most notable are the deer mouse and the white-footed mouse, which sometimes invade cabins and outbuildings in Southern and Western States. The house mouse is distinguished from the deer mouse and the white-footed mouse by its overall gray-colored coat. The other two species have a white underside with a distinct line of demarcation between the dark coloration on top and the white underside. In addition, the tail on the house mouse has almost no fur on it, whereas the tails of the deer mouse and the white-footed mouse are moderately to well furred and are light underneath and dark on top. Mice have keen senses of taste, hearing, smell, and touch.
They are excellent climbers and can run up any rough vertical surface. They will run horizontally along wire cables or ropes and can jump up to 12 inches from the floor onto a flat surface. House mice frequently find their way into homes in the fall of the year, when outdoor temperatures at night become colder. In a single year, a female may have 5 to 10 litters of about 5 or 6 young. Young are born 19 to 21 days after mating, and they reach reproductive maturity in 6 to 10 weeks. The life span of a mouse is probably 9 to 12 months.
Because house mice are so small, they can gain entry into homes and other buildings much more easily than rats. As a result, house mouse infestations are probably 10 to 20 times more common than rat infestations. Effective control involves sanitation, exclusion, and population reduction. Sanitation and exclusion are preventive measures. When a mouse infestation already exists, some form of population reduction such as trapping or baiting is almost always necessary. A key to successful long-term mouse control is the limitation of shelter and of food sources wherever possible.
Trapping works well when mice are not numerous, or it can be used as a follow-up measure after a baiting program. When considering a baiting program, decide if the presence of dead mice will cause an odor or sanitation problem. If so, trapping may be the best approach. Removal of mice should be followed by taking steps to exclude them so that the problem does not recur. Several types of rodenticides are used in baits. The anticoagulant rodenticides are most commonly available and can be used in and around buildings. Because all rodenticides are toxic to humans, pets, and wildlife, take special precautions to prevent the poisoning of nontarget animals.
Because mice can survive in very small areas with limited amounts of food and shelter, their control can be very challenging, especially in and around older structures. Most buildings in which food is stored, handled, or used will support house mice if the mice are not excluded, no matter how good the sanitation. While good sanitation will seldom completely control mice, poor sanitation is sure to attract them and will permit them to thrive in greater numbers. Pay particular attention to eliminating places where mice can find shelter. If they have few places to hide, rest, or build nests and rear their young, they cannot survive in large numbers. Exclusion is the most successful and permanent form of house mouse control. Seal cracks in building foundations and around openings for water pipes, vents, and utility cables with metal or concrete. Doors,windows, and screens should fit tightly. It may be necessary to cover the edges of doors and windows with metal to prevent gnawing. Plastic screening, rubberor vinyl, insulating foam, wood, and other gnawable materials are unsuitable for plugging holes used by mice. They occasionally move into buildings from adjacent fields and woodlots. Deer mice are sometimes called «white-footed» mice. Deer mice also have larger eyes and ears than house mice. Deer mice are active all year, and store food for the winter season much as the tree squirrels do.
