Preventing Critters When Moving Orchids Indoors

Eliminating Pests Before Bringing Orchids Into Garage

Angelo in Orlando keeps orchids on wooden benches in screened patio. In winter, moves them to garage. Wife worries about roaches in bark. Asks for insecticide to water Phalaenopsis and Cattleyas before moving, to mix into water cycle week or two prior.

Expert Response

Angelo, my orchid insecticides don't target roaches. Try sticky paper (two-sided sheets) on potting mix between waterings—bit messy, some mix sticks. Check garden center for chemical recommendations. Previously used Isotox but it's smelly.
