Isn't it a suspended floor?
If the house has a crawl space, it usually means there is a suspended floor with air (=crawl space/crawl height) below it, before the ground starts. I can't imagine that insulation and wooden joists are placed directly on the ground.

Assuming it's a normal suspended floor with a crawl space underneath, it is possible to insulate under the suspended floor where the pipes run to protect them from the cold below. As mentioned earlier, no insulation should be placed on top.

A fundamental problem is that small rodents get into the suspended floor, and have pulverized the insulation under the pipes so that cold can get in, and have created wind tunnels for the polar cold to pass through the insulation.

Since there are small rodents in the suspended floor, and the trash cabinet doesn’t have a sealed floor - don't you have problems with these creatures inside? In that case, you will if the doors to the trash cabinet are left open.

Time to start looking for an access hatch to the crawl space.

Happy hunting.
There is no access hatch to the crawl space. So there's not much point in looking.
I've never had problems with mice running around the residence. It was when the plumber was here that we discovered mouse droppings in the insulation where the pipes are. There have never been mouse droppings anywhere else in the residence. Yes, I am also surprised by this fact. I've also never seen a single mouse. I've barely heard anything either. So they seem to stay in places where you can't see the little sneaky critters.

Exactly so. The mice form small tunnels in the insulation so it drafts cold air through. But it seems hopeless to get rid of these little uninvited guests. :( I have been told that I will have a hard time getting rid of them permanently. They get in everywhere. Apparently, it doesn't matter how much you seal. And that all houses have problems with visiting mice... :cry:

Certainly doesn't sound fun at all. I hate cats, but in the end, I'll probably have to get one anyway.... :devilish:

Cats are very fine animals :love:

When we moved to our cabin, the cats suddenly got very fat and barely ate indoors the first year :oops:

When we later renovated, we saw how many mice had been in the floor! I'll see if I can find some pictures..

Insulation in a crawl space with visible damage, possibly from mice, and scattered debris. Damaged floorboards with insulation exposed underneath, possibly indicating mouse infestation.

When we moved to our cottage, the cats suddenly became very fat and barely ate food indoors the first year :oops:

When we remodeled, we saw how many mice had been in the subfloor! I'll see if I can find a picture..

Oh. Yes, the mice had quite a feast. Did the cats manage to eradicate all the mice, so you were rid of them permanently?
That would be very nice indeed.

When I was a child, grandma had an incredibly cozy cat to whom I formed a strong bond. He was very special, and it laid a good foundation for me to like cats as an adult.

But unfortunately, I compared all cats with this gentleman, so I eventually got it into my head that all cats were like him. And I quickly awoke from that illusion when I couldn't find any cat like grandma's.:rolleyes:

As said, it would be interesting to know if you got rid of all the mice once the cats had eaten them up?:devilish:
 
One cannot get rid of mice permanently. They exist in nature and seek entry into houses when the cold comes. However, one can learn where they are entering even if one seals and then set traps. There aren't many places where they enter our house, but we set traps nearby and it's always a jackpot. Mice are not as smart as rats.

Sure, no more mice in sight in the house. But I'm sure they will come back if the cats disappear, even though I've sealed thoroughly all around.

Very often they enter through the roof. They like to live under the roof tiles. We are also not prepared for them to come in that way. Modern budget roofs without råspont are the worst.

May I ask what material you have used for sealing?

I don't have a modern roof, so they shouldn't get in that way in my house at least:p

All larger gaps with new wood. Other gaps with MS Polymer/Multibond. We replaced the insulation with new fiberglass.

Mouse band and similar might be needed between the outer panel and the wind barrier. We don't have that.

Mouse guard and similar might be needed between the outer panel and the wind paper. We don't have that.
And the fiberglass wool was placed against the foundation? Outer panel is the walls, right? So you tear down the entire wall/walls to seal against mice? Fiberglass wool in the walls too?
Sorry for the dumb question, but as a beginner, I want to know everything about this:D
 
You need to read up a bit more on how wooden houses are constructed.
Simplified, it should look like this from the ground up:
- the ground
- crawl space a few dm
- subfloor of 1-inch thick boards
- floor joists 6-7 inches high and 2 inches wide (one is visible in your picture) with insulation in between
- underlayment of 1 1/4-inch thick boards or 22mm chipboard
- flooring surface

Water pipes should be placed as high as possible in the insulation so they don't end up on the cold side.

Thanks for the response and picture. I read and see that my water pipes are indeed correctly placed under the kitchen sink. The pipes are positioned, as you mentioned, high up in the insulation. Except at this point where the pipes are against the wooden beam or "floor joist".

Thank you so much for the link to this website Träguiden. There is a lot of useful information for me as a beginner to read.

I saw, among other things, that it said there should be an inspection hatch down to the foundation. There is none in my house. I guess I'll have to cut one in the future.

Thanks again for the link. :D

I don't think there are any foolproof solutions. Where do the pipes go? It's best to ensure that mice cannot get to where the pipes go. It sounds a bit strange to insulate the pipes, normally the pipes are placed on the warm side of the insulation in the wall or floor and the pipes themselves have no insulation. If the pipes pass through a cold space, they will freeze regardless of insulation, the insulation only extends the time it takes for them to freeze.
If the pipes pass through a cold space of, for example, 20cm, you can perhaps insulate around 40cm in diameter, so it won't freeze since there are two warm spaces on each side.
