I just noticed my two needle palms have mealybugs. They are 15 gallon size, growing indoors under halide and sodium lighting. I recently purchased them in Florida, and now 1 month later, MEALYBUGS !!!! Florida is a little far for me to do a return. Got em at a fairly good price so whatever will be, will be. Here's my question - Rather than start up a chemical treatment regimen, which will be difficult, if not impossible to do, I was thinking of just placing them outside for a while to hopefully freeze those buggers off. The needles were at 57 degrees inside, but I boldly placed them outside yesterday at 33F, and the temps dropped to 15F overnight. The plants look great despite the cold shocker I put them through. Since they are so cold-hardy, i'm really hoping for this to do the trick. Can this work without killing the palm ? Since they're not coming back inside, I guess time will tell. Anyone ever try something like this before ?
