Pest Control/Could this be a mouse dropping?


QUESTION: I just found this on my carpet. I picked it up with a disinfectant wipe-- neither did it smear nor crumble when I added pressure. (A couple of specks did fall off, but that is it...) It is quite hard.
I'm petrified of rodents, please let me know if I have anything to worry about!

ANSWER: Hi Lynn,
This does not look like a dropping. If it would be rather old and would have to been squished long ago as you described it to be hard and crumbly.

Droppings are usually found in out of the way places where rodents like to hide. One thing you can do is look the home over very closely for any possible entry points where rodents might try to come in.

A simple mouse trap, not set, with some peanut butter on it is a great way to see if you have any unwanted visitors. Place a trap say....under sinks, below appliances, in the garage and the like. If the peanut butter disappears, you may have a visitor. If that happens, simply reapply the peanut butter and spring the trap. (With your aversion to rodents I would suggest you find someone to do this for you.)

If you have any activity or find fresh droppings anywhere....DO NOT USE BAIT! You will be even more unhappy with dead rodents in the house, or worse yet stuck in somewhere where you can't dispose of them.

The key to long term control if there is an issue is to seal up the home, trap the population inside the home (including subarea and attic space)...then and only then bait in locked, secured boxes can be used outside to keep the population down surrounding the home.

Any further questions please don't hesitate to contact me.

QUESTION: Thank you so much for your response.

It did not actually crumble completely-- just a couple of specks fell off.
However-- I did go check it again after an hour or two, because I wanted to check the shape once again. After sitting in the disinfectant wipe for a while, and when I got a new, wetter one, it began to leave some small green smears and became more malleable. Would the moisture from the wipe soften up a dropping, or would it remain hard regardless?

Hello Lynn,

If the item you found was a dried version of just about anything....the moisture from the wipe could re-moisten it.

If it was a old dry dropping, the green color may be a indication that whatever left the dropping may have ingested some bait. It is common to use blue or green dye in rodent baits. Of course this could be a situation where a neighbor has used bait and someone simply tracked a dropping into your house. Mice and Rats generally don't walk out in the open. They prefer out of the way paths such as along walls, under furniture and such.

I would simply keep on the lookout for any indications of activity, either droppings or activity at traps set with attractants.

Hope this helps put your mind at ease.
