Bug Control for Roses

Aphids

• These insects are some of the most common bugs to afflict your roses and numerous varieties exist in the United States. You can utilize a number of other types of insects to get rid of aphids, including soldier beetles and lady beetles. If your roses are part of your landscaping, spraying with a powerful jet of water can ensure that the aphids do not get a foothold on your roses, although you can also use insecticides such as imidacloprid, although you should avoid more toxic insecticides.

Spider Mites

• This variety of insect causes a great deal of damage on roses, often causing the leaves to wither and drop off and they are especially prominent in dry, dusty conditions. If you prefer natural methods of control, you can conserve natural predators, ensure your roses stay thoroughly watered and, if necessary, release predator mites to drop the number of spider mites. Although insecticides are typically not effective in controlling spider mites (and can sometimes cause a flare-up), if you require treatment you can use insecticidal soap, horticultural oil, or neem oil. If using these products, focus on the undersides of the leaves.

Thrips

• This insect typically damages and attacks the flowers of your rose plants, often resulting in browning or in distortion, and these effects are particularly prevalent when the thrips attack the rose during its earliest growth stages. Although insecticides are typically not very effective, clipping and disposal of old blooms can help to reduce thrip outbreaks.

Scale Insescts

• These immobile insects typically cause damage to the canes of roses and there are several species scattered in various parts of the U.S. The cottony cushion scale can allow mold to grow on your roses. To fight an infestation of this bug, cut back your canes during the winter months, and encourage natural predators. Continue pruning the flowers and, if the population does not decrease, wash your rose plants in soap and water. You can also apply insecticidal oil for further treatment and prevention.
