Mice in the attic

Hi All: I just noticed recently that there are mice (or equivalent rodent) in my attic. I can hear them in the upstairs wall near a radiator. I went up into the attic ( I have a cape with an attic) and I found some plastic bags chewed up. I am try to figure out how they are getting is it possible for them to climb up the side of the house on a cable? I can't find any holes or spaces at ground level. Robert

Whereever you enter the attic, stick some traps. That way you can poke your head up and get them without too much trouble. Make sure you tie the traps to something. Occasionally the mouse will drag the trap into the insulation and you can't find it. Soon he is smelling.
I seem to get attic mice in groups of 10. As for holes, they're everywhere. I would find attic insulation in the basement and have no idea how they were dragging it down there..

The rodent problem is the main reason we've adopted a couple of crazy half wild cats as pets. In the last 2 weeks they've bagged three rats that we know of. They help with gophers and mice too. Around here they don't over populate - coyotes, red tailed hawks get them first. Cats are hard on Quail which I see in other parts of town but not in our neighborhood.
Before that we mainly used traps with peanut butter bait. Those glue trays are good for mice but a rat will often get away - even if he looses a leg in the process!
Every year when the weather turns cold, the critters start thinking about winter quarters. One time we found they were getting into the attic thru the garage by jumping up to the furnace and climing up the fiber glass insulation then squeezing between the inch opening around the plenum where it entered the attic. Got most of them by placing the traps where they needed to pass before they could get to the insulation.
Hope this helps, Bob

Mice or squirrels can climb up a chimney or brick with ease. I'm sure they can do the same with a cable or wire going to the house (are your utility wires underground?) Be a detective--Look for holes near the eaves, corners, vents, etc and cover with hardware cloth or metal. You could use D-Con, but that's only a temporary fix.

They can shimmy up a cable or brace themselves against a pipe, gutter, etc. I had them in an attic when I moved in. You can trap,poison,etc but ultimately you're going to have to find where they're getting in unless you just have one of those houses with a million places they can get in at.
I finally located several places they could get in. Closed them off. no more problems. Also cut back tree branches, etc. They have to be getting in somehow...finding its a bitch though as they can make it in very small places. I have concrete barrel roof tiles, lucked out an found a 1 inch hole in a worn sheathing section underneath a tile.
good luck.

Yup. We have a continuing problem with mice in our attic. In one spot, they apparently climbed up the exterior wall either on or in the conduit that houses the electrical wires coming into the house, then somehow made their way over to an attic vent where they chewed through the fiberglass screen stapled to it. We've now added a layer of aluminum screen over that.
