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.

I have a whitefly problem all of a sudden on a hibiscus that has been inside all winter. (We are in Ohio). This is the 3rd year I’ve brought it in–1st year with a problem.
I have two cats who like to eat its leaves. What should I use that will not harm them?

@Bonnie James: First and foremost, I suggest you stop any of your pets from eating hibiscus. I assume you are not aware of the fact that it can be dangerously toxic to pets and even lethal in some cases. A quick “google” and you’ll find a bunch of information on this. When keeping hibiscus and other lily family plants inside the home, be aware they pose a hazard to dogs and cats. Here’s a link to some info on this:
So assuming you make it so your cats can’t get to the plant, I would recommend the organic gardening Multi Insect Killer seen here:
But if you are not able to control the pets and feel there is still a chance of them eating treated plants, use the organic Insecticidal Soap shown here:
Lastly, you might want to apply some Ropel on the plant to get the pets from eating it. They surely won’t like the taste and it’s great to use to stop them chewing/eating things in the home including plants. You can see it here:
