You can blast them off with a hose end sprayer or mix up some insecticidal soap and water and spray your plants.

Keep checking them because the aphids will probably come back.

Good luck,

I've a lot of aphids on my tomatoe plants as well.

I tried both organic and chemical spray it just didn't work well. I think I may have to buy several boxes of lady bug.

Anybody have any good idea, please let me know.

They don't necessarily fall off just because you kill them. Check a few hours after spraying with a magnifying glass to see how many are still alive. I have had success with neem oil against aphids but am currently using soapy insecticidal spray.

I agree with tomatoguy. Check to see if they are dead. Neem oil, as far as I understand, puts them in suspended animation and then they slowly dehydrate. Also, just to be sure, Neem is a contact spray so you have to spray under the leaves. The only aphids I have found Neem oil has problems with are the gray aphids that the ants farm. For them I use strong streams of water and finally pyrethrin. Good luck.
