That sounds totally gross. Could you possibly get a picture of one of them?

I agree that we're going to have to have some decent images.

sounds like Millipedes

I guess they really aren't worms. I was going to say centipede. I just tried to take some pictures and my camera wasn't getting a good close up but as I examined one close up, YES - it looks just like a pic of a milliped.

I'm reading about them now. They like damp areas especially oak leaves. We live out in the woods - many oak leaves and lots of shade so the ground around or under our decks are probably damp.

But why so many all of a sudden????

I don't think we can do anything to take away their food source since we have decks all around our house and plantings all around. I would imagine the mulch is full of them and I need mulch or I'll have all weeds.

My husband just went out to the garage and they are all over the outside of it. He came in saying "GROSS GROSS GROSS".

His question is why now?? We have lived here 31 years and never anything like this. A few in the fall.

I just did a web search on millipede swarms, and after a quick reading, it appears that it is a Japanese variety of millipede that has come to North America, as well as other places, and made a total pest of itself. I must admit that I didn't look at any of the YouTube videos, as it's early in the day and I don't want to puke up my shredded wheat. I didn't look too far, but hopefully you will find something to help. Here's some information on it.

Here is a link that might be useful: Millipede swarms

Everyday ordinary millipedes come indoors now & then -- when it's too warm, too wet, too cold and/or too dry.

Once indoors they die in short order. Sweep & remove.
