They might be aphids. Do a google search for aphids and look at images, and see if they look familiar. If so, I've had them before and they are not hard to get rid of. Just use BATS (Bayer Tree and Shrub), but not as directed...use 2tblsp. per gallon of water and drench the soil, and also spray rubbing alcohol on the aphids themselves. Also spray the alcohol on the leaves and all the nooks and crannies to make sure they are all gone.

Good luck,
Gabi

They're a real pain in the butt! I keep most of my Hoyas inside because they eventually start munching on them outside. But this year, I got them in my GH! (Which is off my kitchen - with screens...) What a pain! Think I finally got them all, though.

The weird thing is that I've been putting a few of my hoyas outside in the Spring and Summer over the past few years, and I have never gotten a single bug on them while outside (nor have I discovered bugs after bringing them in). However, I always have mealy problems inside (and not just with new hoyas I receive). So I don't know...maybe it depends on where one lives?

Hi all,
Gabi you are right about the area you live in..Here in Minnesota there is a big aphids problem, the soybean farmers have the problem BIG time, I think they had to spray for them 3 times this year, the guy that rents my moms farm land had to spray 3 times. So that is why I didn't take my hoyas outside this year.

In Oklahoma Ive seen some aphids lately on the new growth of vines. Seems the aphids prefer tender new growth to the mature growth. I just watered a couple times with the Bayer for Roses mixture and that seemed to take care of it.
I keep a pop bottle of the Bayer for Roses mixed up all the time. I mix mine a tablespoon to a pop bottle and fill with fairly warm water and shake the bottle. I let this sit overnight so the granules melt a bit and shake again before I use it to water with. You should smell an insecticide smell when the mixture is ready to be used. Be sure and keep this bottle marked and out of reach and away from the kitchen so no one mistakes it for soft drink!
I don't let the granules go into the pot as I'm watering. I just refill the bottle with water for next time. I add more granules as the smell of insecticide diminishes.,,,,,Debbie

Thanks for the info, I will give those suggestions a try. I live in Minneapolis. There is a great story behind my hoya. About 3 years ago my dad had called me to say a distant cousin had a "plant" that had belonged to my great-grandmother. She did not want it anymore and asked if he wanted it. This cousin was in the Minneapolis area so I went to pick it up. Good thing I have a pickup, because it was huge. The cousin did not even know what it was called, I googled for images and found out it was a hoya. My sister divided it up into 3 pots for herself, me and our dad. If there is any one in this area who would like a cutting, I would be happy to pass on a cutting from a 50 year old plant....Terri

Hi..
you haven't said what hoya you have, and do you have a picture of it before the trans plant and after?
I would be interested in ctting...
