David –

Monterey Garden Insect Spray is a relatively new organic insect killer that works very well on thrips. However, it will not work on flower beetles. For hard-shelled insects, like beetles, we typically recommend botanical insecticides. These natural pesticides are derived from plants which have insecticidal properties and do not persist in the environment. Botanical insecticides are not specific and will work on a broad range of insect pests, including thrips and beetles. As a result, we recommend spot treating with them to minimize harm to non-target organisms.

Bonide’s Garden Dust is specially formulated to control both insect pests and plant diseases making it particularly well suited for rose gardens. If you’ve had problems with rose diseases in the past, this may be the product you’re looking for.
