First they chomped the neighbor`s grapevines, moved on to my roses and gladiolas. I think those pests are about done for the season and will go away, but for now being as fed up as I am with them I just cut my roses and gladiolas and enjoy them in the house.
Next year we are doing the milky spore and nematodes. And I have been vigilant from the first one I saw in the start, I knock them
into a bucket of water and do that 3 times a day, anyway at least that is less eggs laid as well. As instructed from Google searches many a site said to keep the bucket with the dead ones sitting near what they are eating....but I see no difference, they still come.
