I just read up on aphids and greenhouses, because it seems even my small patio version is attracting quite a few uninvited guests. Crying And, what I thought at first must be fruit flies, I think after reading more must be the winged-stage of reproduction of aphids too. I read that this cycle of aphids can get established and live inside greenhouses indefinitely.

I'm trying to overwinter tender young seedlings, but so far the number of starter pots that have succumbed to aphid attacks have increased each week. We will not likely get a hard freeze until Jan-Feb, and trying to knock the aphids back with mild soap/water sprays each week is getting old...and not really doing much to protect the seedlings. I can't blast them with water since they are so young and fragile, and the only time ladybugs are sold near me is in the spring.

I can't use anything stronger than soap or oil based products (again, not doing much but keeping some seedlings barely alive) during the warmer months since our dogs are allowed in that yard and spend a lot of times up close with the plants, but perhaps I can try something stronger in a couple of weeks when the temps are low enough that we keep the dogs out of that part of the yard.

Any suggestions, organic or not, about how to eradicate my little greenhouse of aphids?

I (prophylactically) use one of the insect foggers in the fall and then again in the spring. I don't know whether it does any good or not, but does not seem to harm any of my tropical plants, everything from orchids, to staghorn ferns, to bromeliads, and lots of other varieties.

Since I have never had an insect infestation, I don't have hands-on experience in eradicating them.

hydrogen peroxide mixed with the soap and water helps. I have a formula in my potting shed if it hasn't worn off the jug...will look tomorrow.

Thanks Ken and Ginger! My greenhouse is so small that I'm not sure about using a fogger, but will research it further!

Ginger, if you would be so kind, I would love the formula for the hydrogen peroxide mix!!! I have used HP for dipping when I divide my plants, and to very good results. If it might also knock back some of the aphids as a spray (I'm assuming that is what the formula is for) I would be in h-e-a-v-e-n! Hurray!

OK....I mix this in a gallon jug

1/3 peroxide
2/3 water
1/2 tbl.(or a tad less) dish soap (I use dawn)

I got this formula from a friend who found it at an Amish website
