Q. "My conservatory is double glazed 9m x 2.5m x h2.5m. Unheated but frost free. Lots of mealy bugs and aphids on hibiscus brought in for winter. What do you suggest?" From Ray
A. Thanks for the message and if it is unheated then using predators is going to be out of the question, so spraying with SB Invigorator natural spray is the best solution. It will control all soft-bodied pests including mealy bug and aphids and is very effective. Spray every other day for a week and then as and when you need to i.e. if a pest out-break occurs. Being chemical-free, it means then when the temperatures rise in the spring, if you want to you can release living predators and there will not be any chemical residues left-behind to harm them.
