when you asked about this in the other post ... which i cant find..

a cursory review of google indicated a systemic like merit or bayer tree and shrub was used ...

on a small tree [5 footer].. something like that could cost you $20 ... and as i recall you have many extremely large trees ...

you might be looking at hundreds of dollars for professionals to spray these trees ... if not thousands to be rid of this problem .... at that point i would be looking at removal, rather than a lifetime of boat payments to the tree spraying guy ....

if not for the other post.. which perhaps others have not seen.. you offer no facts upon which to come to many more conclusions .... hence the lack of replies ...

you need the opinion of a local professional.. if not 3.. in your area ... not the opinions of peeps on the WWWeb

Well Mr. Ken, I reposted because I found out the name of the insect that was making such a mess and also killing the leaves on my tree. It is a young ash that hasn't seeded yet. You're right, the www is not always a plethora of information. I was in my garage yesterday looking for permithren because I did find a place that said it was helpful in killing the aphid, but instead found some Bifen and since it had that it killed aphids I used it. It did a really good job of taking care of my problem along with a few big legged squash bugs. I found about 5 of them dead on my patio. I also removed the branches and leaf clusters that had a large amount of the aphids and placed them on the burning pile.
My other ash trees do have some small areas of the aphid, but for the most part I see new growth and happy trees. I won't spray them, I'll see if their natural enemy take care of the problem.
