Is Insecticidal soap really effective anymore?
This spring I’ve had an outbreak of aphids in my indoor plants. I’ve been spraying with Safers Insecticidal Soap. I have been spraying weekly for over a month and they keep reappearing. I’m wondering if aphids are becoming resistant to this product. I prefer to not use any chemicals if possible. Since the soap doesn’t appear to be working I’m now trying Neem oil but am not sure if it is effective against aphids. Any suggestions would be appreciated.
