By mid to late winter the mealy bugs have decided to descend in full force on plants in the greenhouse. Lack of air circulation seems to be the prime factor with these pesky little bugs because this is when I always have the most trouble with them, when they have been inside for the winter. Mealy bugs can appear at any time of the year, mind you, but poor air movement, trapped humidity, and cramped quarters seem to be what make them thrive. I don’t think they can survive freezing weather on outdoor plants, or maybe they just hunker down and sit dormant, waiting for warm weather to come back. Indoor plants, however, provide them with a nice place to live when it is cold and icy outside.
