Aphids on my indoor hot peppers
I have an indoor 'greenhouse' that I made out of a tent with a temperature control and fluorescent lights. I'm growing ghost peppers, devil's tongue peppers, and chocolate habaneros. I have about 40 plants. Temperature is around 75F, humidity around 65%.
My problem is aphids. I believe they're green peach aphids. I'll clean the plants one day and the next day, five plants will each have 30+ aphids on them.
I've tried squishing them. It makes me feel good, especially when I imagine I can hear them screaming. But they're back the next day. Then I tried insecticidal soap. It cleans the aphids off, but again they're back.
I've also tried Neem oil, esfenvalerate, cyfluthrin, and bifenthrin. The Neem oil I applied weekly for three weeks. The others I applied once and waited several days. In all cases, I would clean all the plants manually, wait two days, and then check them again. The aphids were back.
My present plan is to stick with neem and squishing. But it's very tedious to pull out each plant to inspect and spray it and it's making this a lot less fun than it should be.
Since this is indoors, beneficial insects are out. Any suggestions? Maybe some sympathy? Thanks in advance.
I went back to Neem oil. I'm spraying it every time I see aphids in large clusters and on all plants every seven days. I squish any lonely aphids I find. Just now, I found four plants with leaves with 10+ aphids on them. This is after a meticulous cleaning less than three days ago.
