Mouse Poop 101◀ Back To Blog
November 3, 2014
This will probably never be a course taught at most colleges, but if you're looking to protect your home against pests, this is the place to start. Hunters study the tracks and droppings of the animals they hunt, so they can zero in on the kill. It seems to make sense that we should do the same when trying to eradicate pests from our house. So, here is everything you need to know about mouse poop.
Quantity. First of all, it is important to note that a single mouse can leave behind 70 droppings a day. Some say this number can be as much as 150! That's a lot of poo, folks. So, your first sign that a mouse left those droppings is the sheer quantity.
Location. Sometimes cockroach poop is mistaken for mouse poop. They do have many visual similarities, and roaches leave their feces in many of the same places mice do, like: in the back of your silverware drawer, in behind food boxes, and under the kitchen sink. But, if you find a smear on the wall, you can know for sure that was a cockroach.
Shape. Mouse droppings are usually about a fourth of an inch and spindle-shaped. If you look closely, you'll notice that they are fat in the middle and taper to a point. Many times, they will also bend in an arch.
Color. Mouse droppings are black, when fresh, and grayish or moldy, when old.
Okay. It's mouse poop. Now what?
There are many things you can learn from mouse droppings. The size of the mouse that left it. The possible number of mice infesting your home. And whether or not they are still active.
If you discover several droppings of different sizes, this is a good indication that mice are breeding in your walls. Varied sizes mean babies are running around.
The age of the droppings can help you determine if the mice are still active in your home. Old droppings have a grayish, dusty look to them, and crumble when squished. Do not touch them with your fingers, mice are known to spread disease and bacterial illness. If the droppings are old, vacuum them up, and wait to see if new ones appear in that area.
Fresh droppings will be shiny and black, with a wet look to them. When squished, they will have a consistency of putty. Fresh droppings means an active infestation. Call a professional and have the mice safely removed. This is not a do-it-yourself pest. Mouse urine and feces contaminate food storage areas, and utensils. These areas need to be cleaned, and your home needs to be sealed from future infestation. Trapping and removing them will not keep your home safe from the health risks of this pest.
