What bugs infest orchids?
The bugs that we see more of are: mealy bugs on dendrobiums and phalaenopses, scale on cattleyas, and aphids on oncidiums. With regular scrutiny and care these insects can be controlled. As orchid-sitters we continually are bringing all types of bugs into our greenhouses on plants from hundreds and hundreds of different owners; therefore, we MUST be careful and constant in our treatment and attention. We have to eradicate those bugs so they won’t spread to other plants. Most books give good descriptions of the bugs and how to get rid of them.
