PLEASE PLEASE PLEASE PLEASE DO NOT use pesticides for this. I'll teach you an old trick that I learned from my grandma. I don't know how this works, but every time I have slugs/snails problem, I leave this out, and it gets them every time. You can bait the slugs and snails using a beer can (any kind of beer, as long as it has a few drops left in it) or a melon rind (watermelon, canteloupe, honeydew, etc). Leave this out overnight, and in the morning it will be covered with slugs. Pick it up using a paper towel, and toss it in the garbage.

Ha! I just figured out these rose slugs are eating the heck out of my roses. Someone said to squish them but they are everywhere!

Great timing on this post as we just cut up a watermelon, lol. Might as well try it.

Please, those are Rose slugs, not slugs that eat your hostas! They are not interested in beer/ watermelons/ honey etc.
Please look up the other post on this topic, apparently we have a huge outbreak here in PA this year! And I'm not going to use any broad acting poisons. I'm just afraid that if I will use both chemicals together I will burn remaining leavers. Maria

Slugs and snails are TOTALLY DIFFERENT than Sawfly Larvae (Rose Slugs). I can NOT tell you Maria whether or not soap/ Spinosad can be mixed with Bayer advanced, that's a question that you would have to ask Bayer.

Ok that makes sense now...of course the melon rinds did nothing for the rose slugs!

Sometimes you have to watch what people recommend on here.

Thank you,Jim!Calling manufacture had never crossed my mind. I think I will end up doing two different applications. Rose slugs are not everywhere yet, so i will treat the climbers first. Little monsters really love this cozy safe space between the walls and thorny branches where nothing can reach them !Usually I just leave them alone, but this year I'm afraid they may distress the bushes too much. Especially they are already tired after the blooming.
Yes, whaas, some people just will give your an advice for the sakes of advice. But mostly this forum is very helpful, I would not have the garden I have without it! Maria

Okay, first of all, I didn't know that rose slugs were different from regular slugs. When she said "rose slugs", I thought that she just meant slugs that are on her roses. Next time, be more specific and we can give you a better suggestion.

Ok, I e-mailed Bayer and got your answer. DO NOT MIX TOGETHER!!!!

Dear James,

Thank you for visiting our website and your inquiry to Bayer Lawn and Garden!

We do not recommend mixing products together. We recommend applying one spray allow it to dry and then apply the other product.

Bayer Advanced products are available at most home improvement centers as well as Co-ops (such as Ace and True Value hardware stores) and independent nursery or plant centers.

If you would like to speak to a representative directly with questions in regards to your Bayer Advanced product please call 1-877-229-3724 and we will be happy to assist you further.

Sincerely, The Bayer Advanced Team

gardenmanya,

In order for Insecticidal soap to work, it must be sprayed directly on the insect. So thorough coverage of the top side and bottom sides of the leaves and canes would be required.

Spinosad, requires thorough coverage and probably would be best if insects were on the bush for best results also.

The more organic route would be to do nothing and let the good insects build-up to fight off the bad ones.
If the number of bad insects becomes to many, then hand-picking or spraying them off with a hose would be an option.

Thank you for going this extra mile Jim! No, washing did not work for me this year. Can not pick up anything that sits 8 foot high on the climber also. Rosarium U. is also thorny like hell! Usually I just pick up, this year is different. They showed up early, and don't show any intention to leave. The damage on climbers unfortunately close to what JBs can create. I have plenty of beneficials around, rarely use any chemicals except for fungicides. You know alfa-alfa, Rose tone, picking. This year beneficials probably overeating, and loosing the battle.
I will try to use Spinoisad selectively tomorrow, and keep my eye on progress.

I used Neem in my garden Saturday and tonight I still had alive Aphids, and Rose Slugs, and Spider Mites..leaf hoppers. LOL

I started having a horrible rose slug (little green caterpillars) problems last year. The organic product Captain Jacks Dead Bug Brew (Spinosad) works great IF you catch them before theres alot of damage. I think thats the key to using any product and to use it regularly. The product claims to control a myriad of other bugs but I didn't seem to notice it worked well for anything else. It might work for aphids but I don't have them right now.
Maybe the Spinosad killed them??

I just recently sprayed our new band roses which were covered in rose slugs with Safers Insecticidal soap.
The rose slugs must have just recently hatched because the damage was just getting started.
About 2 days later I looked under every leaf. Rose slugs were brown, dried up and dead. But, I had to laugh as they were still hanging on to the leaf for dear life. lol

Bethany, how often you apply Spinosad for rose slugs? I kind of hoped that one time application to control the outbreak will be enough?

Please state which Neem product you used. Some/many/most? so called Neem products have had the primary insect active ingredient Azadirachtin removed. The Neem that contains Azadirachtin is listed as a control in the link provided.

"Control
Sawflies are best controlled when young. Several options exist for control. A physical tactic is to simply pick them off by hand. Dislodging them with a stick or a stream of water also works. If using water be sure to spray early enough in the day to allow foliage to be dry by sunset so as not to create favorable conditions for fungal development. Horticultural oil, insecticidal soap and azadiractin (sometimes called neem), are low-toxicity biorational insecticides for young sawflies. Azadiractin is slower acting."
