getting rid of mice in attic; DIY, or for the pros?
« on: November 12, 2018, 12:28:06 PM »
We just moved into our new house a week ago, and last night I heard some activity in the attic; guessing it's a mouse.  I'm trying to figure out if I should try to do this myself or if it's better to get an exterminator early before damage is done.  We just moved in, and the last thing we want is house damage at this point.

I have identified a big hole in the front of the house which is a likely entry point.  I'm going to seal it with steel wool + Great Stuff, and maybe some concrete.  There may be more holes (actually, I guess the typical house has many holes).

If I succeeded in filling all the entry points, then I still need to get rid of the bastard(s).  I guess this means traps, and set up in such a way as to not injure our cat.

Any advice?  I'm happy to do this on my own if it's likely to succeed, but I do not want to waste time, since more more time might lead to more mess and maybe baby mice.

Our house was built in 1885 and had a lot of mice. As in, if we set 15 traps, we'd catch 15 mice. We caught and killed over 80 over them.

Here's my advice:

1. Buy these on Amazon:
It's a 24 pack for $30. They work flawlessly, and much easier to set than the traditional Victor traps, which can be finicky. It's worth it to buy 24 of them... mice aren't at all deterred by seeing other mice stuck in the traps. In fact they seem more attracted to it.

2. While you wait for the traps to arrive, go around the house with a fine tooth comb and seal off any gaps. I use wood, 1/4" hardware cloth, caulk, or expanding foam, depending on the size of hole I'm filling.

3. Bait all 24 with peanut butter.

4. Wait for the sweet sound of traps going off all night long.

We have same problem except I can NOT figure out how they get in the attic.  I've spent years combing over my entire exterior sealing up every god damned single place they could possibly get in but every fall we get a few of them up there.  At about 3am I can hear them crawling around on the drywall above my bed in the attic.  All I can figure is they climb up the stone fašade of my house and find some entry point up on the roof somewhere. 

In any case, about this time of year (did it just this morning) I load up on victor traps and peanut butter and head into the attic for my ritual massacre.  I'll set about 5 or so traps at their hotspot and over the course of the week usually I'll kill a few. 

I keep on reloading the traps until I don't catch anymore for a week or two.  Usually then I'm good until the next year.  It's a real hassle to navigate the attic and I tried to pay a company to come do it for me but I don't think it's cost effective because none of them wanted the business.  I need to let a rat snake or two loose in the attic.

Unless you can figure out how they're getting in then they'll just come back, but clearly that's easier said than done sometimes.

If you're going to crawl around your attic be careful of the drywall.  Just walking around up there can cause screw pops and cracking, yet alone if you happened to put a foot through it!

I might chime in with some more thoughts later (I'm going through something similar for the first time in this house after 5 years).

But, if there is any chance that it will get wet, do yourself a favor and replace the steel wool with copper wool. It doesn't rust or stain nearly as bad as steel wool does.
