Sorry, internetiot, ur thread on EW was hijacked but there only so much one can say about them. My suggestion is treat any area u want EWs like one of those EW farms u can purchase to raise worms in, 1) add organic matter (kitchen waste, veggy peelings etc., shredded paper, leaves, grass clippings, etc. 2) if worms don't show up fast enough for u buy some worms. Territorial Seed Co. and other seed companies sell them. "Seed" the area u chose with them. TaDa worms in ur garden. spedigrees, good sites thank u. kimmq, GM, GE, GMO is a process that you and I can't do, unless u have an elaborate lab tucked in ur garage - I don't. I love Gerbera Daisys, my budget only allowed for the purchase of 6 light pink. One of those plants was a lighter pink, yes yes, I will protect it with my life (not totally nuts just budget limitations). That said I needed/wanted more lite pink plants so I stuck my finger in the lightest pink ones every time I passed by, when it produced seed I planted them. It took 2 tries before I had results, 14 plants, will they be like the mother plant? Since I did not "bag" those blooms some other little "helper" could have had a go at the same lite blooms. When these new plants bloom I will know if I succeeded in producing more lite pink Gerbera Daisys huh. If a pollinator, wind, or me caused the resulting lite pink blooms I consider it all a Natural way, if me or nature produces something that, like me taking the bloom from a white Gerbera and rubbing it on the pink one, it is nothing more than what a bee could have done. Still a natural process. GM, GE, GMO, requires manipulation of the DNA with elaborate equipment in a lab. :)

I wish this post came with a solid answer, as I am 100% dealing with the same problem. I live in eastern WV. I have a small 50 gallon pond with 2 filters- one for the spillway/waterfall, the second for a small fountain thing and a frog thing that spits water, and a layer of smallish rocks at the bottom. We shutdown the filters for winter, and at the beginning of April we went out to clean the muck and debris that had accumulated. There were giant (and by giant, I am not exaggerating when I say one of them was at least 10" long) earthworm looking things EVERYWHERE in the water! They were NOT dead, some of them seemed to be grouped around what *looked like* bloated ticks (that's what I originally thought, but after some research, they might have been eggs?). We got out the ones we could see, put a water clarifying agent in the water and started the pumps up. I tried to research what the heck we were seeing, and I couldn't get a solid answer because of these people who just want to argue about what you actually saw in your own pond. It wasn't limited to this page. April 18th (about a week or two later), the spillway pump was down to a trickle, and the water fountain had tiny little worms (these looked like tiny earthworms, not red in color) coming out of the holes. We took the filters out, cleaned the muck off from them and found tiny worms were INSIDE the filter mesh. Soooooo.... we went out and bought some goldfish to put in there. Fish like worms, right?? Obviously a tiny goldfish isn't going to eat a 10" worm, but we were hoping they would go after the babies... eggs... larvae? Two days ago, April 27, the spillway was slowing down to a trickle again, the fountain was fine, though. Again cleaned muck, found worms. My husband pushed some of the rocks at the bottom around, and more of these giant worms started popping out. We decided to just start shoveling the rocks out. There really wasn't any plan beyond that, just get as many rocks out as we can, and go from there. So. Many. Worms. This time I got pictures of some of them! As my husband is shoveling these rocks out (being extra careful not to puncture the lining, or a goldfish), I'm spraying them off with a hose. Besides the giant earthworm looking guys woven through the rocks (and very much alive), there's teeny-tiny red worms attached to the rocks, as well. What the heck is going on in my pond?! The internet has not been helpful. I've learned more about worms than I ever wanted to know, but I have zero answers to my own problems. I either have glycera bloodworms (because of the tiny red worms), nightcrawlers (because of the full grown looking worms), and/or non-biting midge fly larvae (because those are also tiny red worms called bloodworms). Terrifying fun fact, glycera bloodworms have metal teeth, and they bite 😐. I wish I could go back to last year when the only "problem" we had in the pond were tadpoles. Help? Anyone? Suggestions (besides taking a flame thrower to my whole backyard, my husband said that isn't an option)? This is too much nature for me. Nature is gross. At least they aren't African Jumping Worms, because that's a thing. *gag*

I think I would wet/dry vac them up before they dried. Try plugging up the drain holes with someting that will allow water to drain like bronze wool, landscape fabric or similar. More likely they are crawling under the sliding door sills. Caulk the track at the slab. Make an effort to see how they are getting in. Take a beer or glass of wine and spend some recon time on your patio when it rains. I thing John was thinking to attract birds that also might eat the worms. A chicken or 2 would probably have a feast & learn where to go when it rains for the treat.

Oddly enough to many gardeners, earthworms are heavily implicated in a number of serious negative impacts on our native plant communities, at least up here. In short, the glaciers removed all earthworm species from vast swaths of N. America and all-yes- all of those worms you see in places like this are invasive species! Florida of course did not get glaciated but that doesn't mean those big European nightcrawlers belong there......or whatever worms you may be finding. This is an emerging topic and I admit to being on the fence about some aspects of it, but earthworms are held in a much dimmer light in some circles than the average gardener might imagine. People dumping their leftover bait after fishing is thought to be one means by which this has happened, and in that case mea culpa. Not these days but long ago.
