I received two orders of green lacewing larvae two weeks apart...about $40 for a total of 2000. I released them as specified into a sealed screened growhouse 10' x25'. Nothing happened. That is, I was not at all clear there was any decrease in the aphid population, but I am absolutely sure if the lacewings had matured I would have seen at least one! I saw none. After waiting two months for them to mature I called the company. The woman at Arabico said I couldn't see them...that is adult green lacewings are too small to see...which is, of course, false. Her "solution" to my problem was that I buy more. Absurd! Its a scam!

I made my negative comments in the summer of '11. Around Christmas of '11, I got a call from an owner of the Arbico who wanted to 'make it right' and said she wanted to keep in touch throughout the year. She sent way more than the replacement of $40 of dud green lacewings: organic micronutrients, nematodes, more lacewings, organic fertilizer, etc. She did not include her contact number and I haven't heard from her since...but that's okay. I tried the lacewings again this summer of '12 and I have seen both a decrease in my pest population and a few adult lacewings. Arbico is sending the lacewing larvae out in more sophisticated cool packs and that may account for the difference in results.
