Hi: Been meaning to ask this question since last summer.

I have two areas where I have hosta plants. Last summer in the one area the majority of my hosta plants were attacked by something. I looked and looked, but could not see anything ... maybe someone else has had this experience?

The end result was that the leaves of the hosta plants were eaten ... just the hard green part, and left behind were leaves that looked like a fine layer of see- through silk. The plant itself was all droopy with these cobweb type leaves?

I sprayed and sprinkled and did everything I could think of and everything the local nursery could think of to no avail. Eventually I just cut them all down to the ground (around end of July) and they never showed any signs of life after that ... I guess I will find out this spring if any of them survived.

The hosta plants are shaded by pine trees and to the left of them my neighbor has Chinese Elm hedge (nasty things that attract Japanese Beatles and seem to grow a foot a month).

Any ideas? Thank you.

I'm thinking when they get chewed like swiss cheese... it's earwigs.

I had quite a few last summer that were chewed down to nothing... i had heard a radio report that the earwigs were bad in our area over the summer.

I find slug holes and cutworms look different from the earwig 'munchings'.

they should all come back for your next season.

Thank you. That is VERY encouraging. is there a way to poison earwigs?

I'm sure there is... I've never seen them in the act on my hostas... i'm sure they are out at night... but i'd bet a 'soap and water' spray would do it. ...i use that to kill certain bugs, but the soap has to come in contact with them.

Warburton - I'd bet on earwigs also. Did you want only an organic treatment?

Late night forays into my garden last summer showed about 50/50 slugs and earwigs on the hosta leaves. Earwigs are readily dispatched by a soap and water spray but you have to hit them. I think one of the easier things to do is to lay pieces of old hose in a dark, damp spot in to garden. In the morning, you just dump the critters into a bucket of soapy water. Trouble is I don't have any old hose. Should check garage sales in the spring.

I had a ready spray container of 1 part ammonia:20 parts water (or a bit less) with some insecticidal soap added in for good measure. If I found the critters late at night, I sprayed.

Warburton - where in Rochester do you live? I grew up in Fairport.

Hi All:

I live in Chili ... the west side ... you grew up on the east side.

Do I only want to use organic? NO. I want to use whatever will kill the earwigs so that they do not have the option to trash my hosta garden again.

I would prefer not to have to go out and hunt the creatures at night ... just like to find something to spray on the hosta plants to kill off the earwigs ... they really destroyed my one hosta garden last year ... made me sad!!

Thanks for all your input. Warburton

Try this product. It kills snails/slugs/earwigs. Getting the first generation of any of them in the spring will drastically reduce the population for the rest of the year.

Hi Pirl: Thank you for the information ... The Garden Factory opens March 1st, I have marked my calendar on Monday March 1st in BIG RED LETTERS ... to to Garden Factory, buy Ortho Bug-Geta Plus.

Here's hoping.

P.S. ViolaAnn I love going to Canal Days in Fairport in the summer ... I have taken my grand children on a canal trip in the past and spent a lot of money on the 'arts and crafts' ... Fairport is a very pretty town.

Call to be sure they carry the product line. Home Depot may have it as well.

I've honestly never seen damage like that on my hosta- and I have a lot of slugs and earwigs. The only time I've ever seen cobweb leaves is from Japanese Beetles...but I've never once seen one of those on my hosta either. I do have issues with slugs eating holes in the hosta petioles, causing the leaves to collapse.

I'd give that Ortho stuff a shot, and hopefully it will take care of whatever is causing your problem.

If it should happen again please take photos of all parts of the hosta so we can help you further.

Okay Pirl, if it happens again (here's hoping it goes not), I will take photos and post them ... I hate the thought that I will lose the joy of that hosta garden AGAIN.

Noreaster has been through it more times than is imaginable. She hunts down slugs and earwigs at night and does her best but the evil critters hide (as they do so well) so it's a constant battle some of us have to fight.

I have lilies close to clematis and used a lot of the Bug Geta Plus around the clem's and the nearby hostas with no ill effects on any plants.

What does "spary" mean?

I despise the damage done by both earwigs and slugs! Just look at the damage they did to the hostas in this photo! There was ajuga to the rear, as you can see here, and I removed it all but the damage continued and that's when I resorted to the Ortho product with success. I'd still reapply it every few weeks just to be safe.

I am so glad that I happened upon this thread. I lost my slug "No Mercy" supplier last year and my hosta's really showed it. I will try to remember the Ortho Bug-Geta Plus. I am going to look for it first thing tomorrow.

Hi, Kelly! Good to have you back with us!

I had a dream that I used a leaf blower to get rid of the top layer of soil in one small garden to see if the eggs would go flying as well. I'd put all of that soil back into the compost pile.

It always surprises me that I don't find slugs in compost but I have found some in open bags of manure.

Same here. Repulsive is a good word for them and maybe how they feel about us giants.

I am use to the slugs, try a small tuna can filled with room temperature beer. The will dive right in and drown.
My problem is the cracks that have suddenly appeared. Like something is eating them in lines. Sounds crazy. It's very unattractive. I also have these crack lines in some Dahlias and Peony.
