Mice or Rats? How to tell the difference
Inspecting for Rodents With a flashlight, examine dark areas, such as behind appliances and in cupboards or closets, where rodents like to hide. And be sure to look up, down and all around for signs where rodents travel.
A good inspection will help you determine:
The type of rodent - is it a house mouse, Norway rat or roof rat?
The severity of the problem
Where they eat, travel, and nest
The cause of your problem - whether it's poor sanitation, available food, or water
The best type of rodent control product to use and where to place it for success
Signs of Rodents Tell-tale signs of rats and mice include:
Rub and gnaw marks
Unusual pet behavior
How to Tell if You Have Mice or Rats You know or suspect there are rodents in the house, but how can you tell if you’re dealing with mice or rats? Even though they share common signs, use their unique indicators to find out what kind of rodents are present. This is also important so you know the right bait or trap to use to get rid of them. Appearance. Rats are larger than m
ice and will have coarse red, brown, grey, or black fur (depending on the variety) and a long, scaly, fur-less tail. A mature rat can range from 11-19 inches long (including its tail) and weigh ½ to 1 pound. Mice have large ears and tiny black eyes. They have fine fur that can be black, grey, or brown and a 3-4 inch long, hairless tail. Mature mice grow to about 6-7 inches long (including its tail) and weigh ½ to 1oz. Droppings. Rodent droppings are a sure sign that rats or mice are present, and will indicate the type of rodent, the size of the infestation, and where they are most active.
Mouse droppings are small, less than ¼ inch, and pointed on both ends.
Rat droppings are ½ inch or larger.
Norway Rat droppings are blunt at both ends, while Roof Rat droppings have pointed ends.
New droppings are shiny and putty-like in texture, while old ones are hard and crumbly. Varying feces sizes indicate that juveniles and adults are present, and lots of droppings may be an indication of a large infestation. The location of the droppings indicates active areas where you should place bait or traps. Urine Odor. Rodent urine has a strong musky odor. With large infestations, you can easily smell it. Gnawed Holes. Gnawed mouse holes are small, clear-cut, and about the size of a dime. Gnawed rat holes are large, about the size of a quarter, with rough torn edges. Rub and Gnaw Marks. Oily ru
b marks are left in places where rodents travel along walls. If rub marks smear, you know they are fresh. Gnaw marks on wood around the house also are a sign. Tooth marks about ⅛ inch long are typical of rats and small scratch marks are a sign of mice. Runways. Common rodent pathways are generally along interior walls, building foundations, ledges, pipes, electrical wires, conduits, tree branches and fence rails. Nests. Mice will shred paper, string, and other pliable materials to build their nests indoors. Norway rats nest outdoors in burrows deep in the ground. Roof rats typically nest above ground in attics, trees, or dense vegetation. Noises. Rodents are nocturnal. At night they often create scratching sounds as they run inside walls and along floors. Pet Behavior. Pets tend to act unusual when they hear or smell rodents in the house. They may appear extremely alert, bark, or begin to paw at spaces beneath refrigerators, stoves, or low-clearance pieces of furnit
