Why am I finding garden worms in my house, what are they attracted to and how can I stop them?

Question

I dont have any pets or children! and they seem to be getting in when my front door is closed and not open!

Answer 1

It must be damp. thay are like slugs and attracted to damp houses. Have you got a cat? they bring them in.

Answer 2

Do you have a cat? or small children?

OK, there are some exotics like you have a dirt floor or a mud hut.

If you rule these out you are going to have to get up close and personal.  Oh and by the way they are probably more lost than attracted to.

Since they obviously start out outside and underground you have to start outside, local to where you are finding them inside.  You are looking for two things, somewhere where they like to be and a means of entering your house: a pile of debris against a wall and hole in the wall are the obvious things.  However that would be too obvious and you would have found it yourself by now.

Sorry you are on your own.
