New build house with woodlouse infestation

MeganA

I moved into a new build house 3 months ago, and every day I’ve been finding woodlouse indoors, sometimes one a day, but on occasions multiple, only after finding 7 in the space of 10 minutes. I know they aren’t harmful, but I don’t want them in my home!!
Also outside at the back of the house the wall seems to have a few inches of green algae/damp a few inches up the wall, which I’ve been spraying with hypochlorite to kill off.
I contacted my developer about the green on the walls and he said that was just something that was going to be there but it wouldn’t go past the waterproof membrane so no need to worry.
But I’ve also been noticing there’s a gap under my skirting and a small greenish/powdery seeping from underneath which I’ve had to keep running away, and since I’ve used the hypochlorite outside it seen toe be black instead of green?!?

I’m sure these are bound to be related and I feel like the woodlouse are coming in through the walls because I’ve never found any coming down a window or on a window sill, always along the edges of the walls.

What are my rights in getting this looked at and getting it fixed? And does anyone have any advise on how to fix it? Also due a baby in 4 days and this is definitely not what I want 😭

That does sound rather damp. Have you got any pictures? Any idea if there are pipes going through that section of wall?

Woodlice like damp conditions and those conditions shouldn't exist in a new build house.

Yup. Pictures, please!

This isn't 'one of those things'.

That certainly doesn't sound right.

Our new build has a small amount of green on the very first course of brick above ground level but that is all, certainly not enough to be noticeable unless you are really looking for it.

I would be getting the developers back to look at what is going on behind your skirting board and sorting that out. It doesn't sound right at all and they need to address the problem before it becomes more widespread.

Woodlouse inhabit damp areas so that is an early warning that something isn't quite right.
