I like to spray a mix of dish soap and water, a few drops of Palmolive or Sunlight in a small spritzer bottle out of the direct sun and this usually takes care of small infestations with routine checks to respray if needed. I think there is someone on here in your area that had the same problem and maybe they can give more specific advice.
Good luck. ~ Mary

Sounds like aphids. Go to the posting awhile back I've linked below.

Thanks for the advice!
I have been using Denise's (Alcohol/water and dish soap
mixture and it helps but I just keep seeing them over and over. I have all of my Hoyas in my greenhouse and all of them seem to be doing real good...except for those little orange devils! I'll just keep spraying and watching for the good advice I get here. Grmadarr
