Pests on a tree outside, danger? W/ Pics

IrrelephantNovember 11, 2013

Through circumstances out of my control, I have to move to a small house a mile or two away from where I'm currently living. I would never leave my plants behind, so I've set aside a nice sunny room in this house for them. When it isn't winter, I love to keep the majority of my plants outside. However, there is a tree covered in some pest. It blankets one limb of the three so that you can only see white.

What are these pests?
What can I do to get rid of them?
Do I have to get rid of them? I'd rather not half my plants covered in little white crawlies.

Where are you located? What kind of tree is that? Are other trees and plants affected? My first impression from most of your photos was white flies, which are big trouble in my experience. But the second and last photos look more like wooly aphids to me. They don't usually cause a lot of damage and are usually only attracted to a single species, unlike white flies. You might google images of each pest to compare.

After googling it, it's not wooly aphid, and I don't think it's white fly. Arkansas, and I'll try to ID the tree next time I'm over there.

Can you contact a local county extension office or university horticultural program to ask what pests are in your area? I would be pretty nervous about putting my plants near those guys too. If they are confined to one tree (or kind of tree), you may want to consider removing it. In my experience, plants aren't often overwhelmed by a pest like that unless they are already weakened by other things like disease. Sorry I can't offer more specific advice. It's best to find out what they are before using any pesticide.
