Worms around Hot Tub - any solutions? (to buy, organic)

[Two-K]

I'm posting for a neighbor, he's had this problem for a couple of years but this is the first time he's called me over for a look. I realize the recent heavy rain has a lot to do with them coming out of his lawn, possibly to mate, and I'm pretty sure this problem isn't unique to the southeast valley. As much as he's an earth friendly individual, it's obvious something needs to be done, up to and including poison.

His lawn is about 45' x 30' and butts up to the slab where his tub sits. My desert landscaped back yard starts only 15' from his hot tub, and I've never seen a single worm in the 6 years we've been here. Short of ripping up the lawn, can anyone suggest a solution? And if it does involve pesticide, what worked for you?

Bacillus thuringiensis (or Bt) is a natural worm killer found at any Garden Center.

Diatomaceous Earth would be a 2nd choice.

Well, they're trying to find a high spot so they don't drown underground and the hottub is it. Maybe put down a board or something that can retain moisture on the ground and see if they stick to that instead?

When is the last time you checked the chlorine level of the water ?
worms live on bacteria.
If you have a mulch pile/ garden, I'd put them in there.

EARTHWORMS!!

Obviously something needs to be done!!
Good grief they're good for the soil and are doing what they do when the ground is soaked. I'd leave them be. When the ground dries out they'll go back into the soil.

Where does he live? Can I come get them? I was thinking of starting an earthworm farm next to my compost pile...
Are they damaging anything? Where are the birds? Whenever the worms start coming out of the ground in my yard, the birds see them from a mile away and swoop down for lunch.

Try baking soda all around the hot tub. If no children or pets in the area, also sprinkle baking soda over the entire concrete area as well. Green caterpillars drop out of nearby trees where I live so I put baking soda on the track of my sliding glass door, they curl up and die. I can't sprinkle my whole patio because neighbor's cats like to lay on my patio sometimes.

Amazing problem to have, and it isn't even a problem. Ah, to be vain..

They are so good for your soil and are completely harmless. I was just looking for a place to buy some so I could improve the soil in my yard.

I suppose if you really need to get rid of them, for reasons beyond my comprehension, you could attract worm eating birds to your yard. There are tips available on the Internet about that.

Even if he poisons the current batch of earthworms, which I wouldn't do, he'll just have more worms down the line when it rains. Personally I'd just relocate the earthworms to the top of the soil around a garden, where there are plants, etc. When the soil dries out a bit, they'll dive back underground and you'll have natural soil aerators and auto-fertilizer generators making your neighbors plants happy. If it were my neighbor and they didn't want to do that, I'd offer to relocate the worms to my yard and put them in my garden. I'm also a bit surprised the birds haven't located them and had a big dinner.
