No idea what the shrub is, but when I've had a white fly infestation (they can explode into a large population before I've even noticed!) a couple of heavy (dripping) sprays of neem oil has taken care of it.

Thanks Roselee! I'll check, I think that I have that in my box of goodies.

Yaupon holly methinks

or a cherry laurel, does it have thorns? Berries?
Whitefly are a huge problem. You can paint a board yellow, hang it in the tree, cover one side with cooking oil. The whitefly are attracted to the yellow and stick to the oil. Rinse off, repeat.
Tally HO!

Very interesting trearment , Beeachplant. Yellow makes me think of my mom. Is their any oils yhat works better than another oil. Does this work for nuisances like flea beetle?

Natural Gardener recommends Organix or three applications of Neem oil a week apart. I think you are only supposed to use Neem during cooler temps. I have a terrible whitefly infestation on a rosebush and will be applying something this weekend.

It does look like Yaupon Holly but is completely devoid of flowers or berries. It's not Cherry Laurel for sure, the leaves are small, only an inch long and maybe 1/3 of an inch wide.

I went to the Aggie horticulture website and learned that whitefly are a food source for ladybugs and lacewings. Now I am wondering about neem oil or Rotenone. I don't want to do in any beneficials.

What would you do? I'm always so torn when it comes to the beneficial insects.

the cherry laurel in my yard had tiny leaves, it was so deprived of nutrients. I cut that thing down!

Any type of oil works, I use cannola cause that`s what`s in the house. It works for a huge number of insects, most are for some reason attracted to the color yellow. I really kind of gave up on controlling whitefly years ago, no matter what I`ve tried they have a couple of plants they like and they take over. Usually buy lady bugs in the spring and release those too.
Tally HO!

I guess with so much whitefly damage you probably don't have that many beneficial insects around anyway. I'd go ahead and spray.

Me too. Agreeing with grinchis40 ....

Good point, nothing to lose unless I don't act now. I've seen a few lacewings but really only a few.
