What is the best way to control scarab beetles on my roses? I encourage them to go for a swim in soapy water, but some fly away before diving. Others I spray with soapy water, but it seems to just slow them down. Worse yet, they seem to be mating on the plants. I have very few roses left because I have been deadheading the eaten ones. What else can I do to control them and is the situation likely to be different next year?

Hello,
Sorry to hear about your beetle problem. Scarab Beetles come in many varieties. A few photos would be necessary to identify the type of beetle so we could give a more accurate answer.
I am including a link to a fact sheet regarding Japanese Beetles which can be a problem on rose bushes. http://extension.colostate.edu/topic-areas/insects/japanese-beetle-5-601/
Please let us know if we can be of further assistance.
They are, in fact, the Japanese variety. I can take them diving 10 times a day, yet there are always more.
Yes, they can be very frustrating to deal with. Hopefully the fact sheet link provided some helpful suggestions.
Let us know if we can be of further help.
