if it is inside a greenhouse, have u thought of using natural biological control? ladybugs are mean "red' killing machines when they come to aphids ^^ but also rmb that everyone of them (aphid) has to go, young or mature since they are born capable to reproducing without mating... i hate those suckers... killed all my roses...

Philoserenus, they were not in a greenhouse, they were in the house and sice the weather improved I put them outside, I have no idea as of how they managed to get there.

And yes, I've seen what they can do, and I also know they can spontaneously reproduce :((

I trust for everything to be ok soon :)

UPDATE: I wiped the leaves and stems of all my chids with Ortho Plant Care Plus (Home Depot I went didn't have Schultz in stock) so far, so good, there were no signs of pests this morning :)

Good for you there is nothing like giving your chids some TLC
