well, that will kill the bugs inside but when you bring the plants back in you will re infest the house with the whiteflies that were taken out on the plants and brought back in. that is the object of a systemic. very effective in the Winter when there are no "good" bugs to damage. You do not want to use malathion where the bees can get a drift of it. what are you using to apply your sprays with? that might make a difference. are you completely covering the entire plant with the product. we use a back pack sprayer with an engine outside and a 3 gallon back pack "hand pump" sprayer for inside. turn the nozzle so it is pointing up towards the foliage from underneath while spraying, too. You need to cover everything. and do you put in a few drops of spreader sticker? that makes a huge improvement on effectiveness. I don't use met52 ... these are just tricks and tips we have learned over the years that work for us. is met52 a contact spray or does it have a residual effect? check to see what the Ph of the effectiveness of the spray needs to be at in order to be most efficient... if it matters... check (and change if need be) the Ph of your finished product before spraying it.
