Our first child is due any day now, and we've got a mouse infestation. We noticed it for the first time at my girlfriend's baby shower (lots of cakes and crumbs out), and since then we've started seeing it more frequently. I say "it", but we suspect more than one of them, based on other people's comments.

Obviously we're trying to de-mouse the house, but how concerned should we be about mice in a house with a child?

    This doesn't really have anything to do with parenting. You may want to consult with an exterminator.

  • This question seems to be less about parenting and more about home improvement -- at least mouse infestations are discussed frequently there. Apr 20, 2012 at 11:19
  • Makes sense, I'll migrate.

  • I've actually edited the question to be more parenting-related, as I think this is a common concern for young parents.

Some studies (news article, another article, actual study) have shown that mice fecal matter could contribute to asthma, or otherwise cause allergies in young children.

In a study of eight cities, a team from Johns Hopkins University in Baltimore, US, checked the contents of dust samples from the homes of children with asthma.

The team found that 95% of those samples contained mouse allergens, many involving feces or urine.

Other concerns include: mouse droppings can pose to be a choking hazard; mice can eat up your furniture, wiring, and insulation; they may clog plumbing etc. in your house, creating fire hazards; and much more.

Murine Typhus Fever or simply Typhus is spread by the bites of fleas that have fed off of rodents. This infectious disease shows itself with a rash and other symptoms include headache, backache, a high fever that may last up to two weeks, nausea, vomiting, and abdominal pain. Treatment for typhus fever includes antibiotics and over 98% of people afflicted will recover. 10% to 60% of people who do not go on antibiotic treatment will not survive

Living with a mice infestation is dangerous for human beings in general; it is only going to be more dangerous for a helpless child to be there.


No more than in a house without a child. Which is to say, the mice have to go. Mice leak urine as they walk -- "like drunken hoboes," as MimiSmartyPants so memorably put it last year. They're nasty little brutes.

First, seal up your foundation. (I did it last year and it took half a bag of cement and four cans of spray foam. Thank you, lazy house-builder!) Then buy some spring traps, smear on peanut butter, and place them near the basement walls. Get ready to collect the little bodies.

  • Rented accomodation from the 1900's. Suspect that sealing the foundation may be a tad harder for us. Good advice on the traps, thanks.

  • Oh, that makes it harder. Yeah, you may be forced to launch a Reign Of Terror in mouseland. My condolences: sometimes it gets downright nasty. :7(
