All I have is a Hibiscus plant that has become infested with white fly. I have had the plant for at least 25 years so it has sentimental value. I moved it outside, treated it with all the normal insectisides and seemed to get results but they just come back. Now after reading this literature I see why. I have moved the plant outside, trimmed it way back and repotted it. It is in a 20 inch pot. From the info in this article i think i would prefer fogging it. Could I enclose it in plastic and use one of the foggers successfully?
Using one of the foggers we have listed in our WHITE FLY CONTROL ARTICLE would not be an option if you wanted to use it in an enclosure of plastic like you described above. This method would concentrate the aerosol so intensely that there would be untold amounts of damage to the plant which would almost assuredly lead to it’s demise. In other words, I think you’d kill it!
The best approach would be to get one of the concentrates we have in the article and start treating it on a regular basis. The Organic INSECTICIDAL SOAP option would work but you’ll need to treat every 2-3 days. ORGANIC MULTI INSECT KILLER will last longer but you’ll need to use it every 4-7 days. The BIFEN IT will be the best option and should last 1-2 weeks per treatment providing excellent residual. The key to breaking the white fly cycle is stopping their young from developing and this will require multiple treatments on a fairly regular treatment schedule. Note that the fogger would have the same impact as spraying so you’d have to fog every 4-7 days even if was something I was recommending so there is no benefit of using it compared to the spray.
