They decimated our three Joe Pye Weed plants Grumbling chewing off about half of the 2-3 inch shoots, as well as getting to our beloved "Henri" clematis- AGAIN!!! Angry caught one in the act squirming its way up Henri's trellis. I swear, Henri is never going to even reach 3 feet tall if they don't leave him alone Sad then found one on the underside of one of our "dream queen" hosta leaves. just about ready to break out the big guns...

What have you already tried to prevent or eliminate the slugs?

Hi Riverman,

I had that trouble with my hostas and because pellets aren't a good idea (afraid hedgehogs would eat the poisoned slugs), I ended up creating a barrier. There is this natural clay product you can put down which is in chips and should a slug glide across it, it dries it out coupled with the texture they didn't like. Once I did that, no more slugs on my hostas.

I hope that helps.

Do you have a complete barrier around the plants they are attacking? I am guessing you tried beer traps as well?

@bennysplace -- Benny, is the natural clay product the diatomaceous earth? (I didn't think that was clay....) In any case, would you share the name of the clay product? I'm very interested in this! Thanks.

It took a lot of trial and error for me to combat my slug problems. I set beer traps, I went out at night with a flashlight and hand picked them, etc. I knew I could never use pellets so I did some research and I found the clay type product I mentioned above. I spread this like you would a mulch in a circle that was perhaps 3 feet in diameter. I tried with one hosta at first and noticed no slug damage so spread around all of them. From that moment, I defeated the slugs and these guys were HUGE... some exceeding the size of my middle finger so they could take a full grown hosta down to nothing overnight so you could imagine my frustration. I didn't use DE then but if I had a slug problem today, I would use it.

Hi there kylaluaz,

I am trying desperately to find it. :)

I had this problem when I lived in England and I found it at a local garden center that sold only non toxic products to get rid of pests. If I can't find it on the web, I am going to call that garden center tomorrow. :)

It is a God send though. It looked like someone took hard clay and pulverized it into chips.

Sounds wonderful! I hope you find it and we can source it here. I like DE but the problem there is as soon as it becomes wet it no longer works. Well, maybe it does on slugs, never tried that.

I do sympathize with this challenge, having lived and gardened in the SF Bay Area and in the PNW also. The only thing I found at all effective was to mount twice or thrice daily patrols, hand pick and dispatch the critters. That did work to a sufficient extent they didn't destroy everything, but there was still damage.

I learned these slugs were an invasive import and not the natural fauna of the areas -- I forget the details but they came from Asia somewhere and outcompeted the locals (such as the banana slug which has a viable role in the ecosystem) and did that invasive thing we know and love so well -- Sticking tongue out Thumbs down

Could you be referring to horticultural grit?

ive never heard of the clay barrier you speak of. believe me, we've tried everything from elephants to shotguns.... we had record warm temps here in the seattle area last winter as well as this spring. the theory goes the weather was so mild that the slug population exploded due to not being killed off last winter. now we're feeling the full brunt of it. It was very warm this past few days and its been raining for more than 24 hours here. slugs are going gangbusters!

Hiya... that product looks interesting but it's not what I used. The stuff I used had the consistency of a thicker cat litter (sort of).

@lovemyhouse.. it is similar to that but it has something in it that dries the slug out as they attempt to cross it.

the old "Cory's" slug killer was great! the powdered stuff would kill them on contact, unlike the "baits" that are out there that simply draw the slugs directly to your plants, giving the slugs a choice, the plants or the bait. 50/50 odds are not what I call good when it comes to getting our hostas shredded.

Comet powdered cleaner is supposed to work. I bought three cans of it years ago but never did try it.

I had good success with a copper penny ring and my slug-magnet ligularia. I can see that I need to do another one, as last year's is no longer effective (likely too covered with dirt). I plan to just place a new one over the old one. Here's a link: http://garden.org/ideas/view/Bonehead/1859/Slug-Necklace/
I want to live in a world where the chicken can cross the road without its motives being questioned.
