I've got a black pepper vine growing on my screened front porch. It was doing lovely and then these clear tiny eggs started covering the under leaf. hundreds of them. I've never seen anything like it before. I rinse them all off, spray pepper spray, hort oil, etc. Still they just won't leave this vine alone. They are on nothing esle and I have LOTS of stuff. Anyone know what it is and how I can get rid of it once and for all? Also why isn't it touching anything esle?
