This is an updated rose midge control option(s) for getting rid of midges in your garden. They are pesky rose pests for sure since they will greatly reduce the flower production of your rose bushes.
If the rose buds and stem tips on your rose plants shrivel and turn black, those are symptoms of damage from midges.
They are very tiny insects that are very problematic because they are barely visible, so you most likely won't notice them until they have already done damage to your rose bushes.
These inconspiceruous flies lay their eggs on the flower buds, stem tips and new foilage of rose bushes.
When the eggs hatch, the midge larvae start feeding on the rose's tender new growth.
This causes distortion and darkening of the buds and other affected parts of the plant, and you will have few, if any, flowers on your bush.
Midges on roses are especially bothersome in the Southeast, Southwest, and on the West Coast of the US.
Wherever they occur, they are the most active in mid-to late summer, as are most rose pests.
That's why I recommend that you hose down your roses with water almost daily during the growing season.
In fact start doing it as soon as new growth start appearing after your annual major pruning.
Because that's when the aphids start getting active.
Washing down your rose bushes daily will greatly reduce the population of common rose pests.
This is something I practice myself, and I have very few pests in my garden, because they never have a chance to populate in great numbers.
If your infestation is severe, spray with an insecticidal soap for roses, which is a less toxic treatment than chemical controls.
You can also combat their soil-borne larvae with an organo-phosphate insecticide such as Pemethrin, which is a chemical treatment.
Another way to control pests in your garden is to apply a dormant oil spray which is a combination of horticultural oil and a fungicide such as lime sulfor, or fixed copper.
A dormant oil smothers and kills insect eggs and kill the organisms of diseases before they become a problem.
This is the most important preventative thing you can do, and it's the only spray I recommend you use every single year right after your prune your roses in late winter or early spring, depending on where you live.
