If you search for the best insecticide for roses, you may be tired of non-stop battles with multiple insects in your garden. To find the most suitable pest control for roses is not that easy since your main priority is to keep the roses alive and unharmed. Not all remedies work the same, and not all of them are suitable for all the pests that attack the flowers. Even one insect can cause damage, and since they usually attack the garden in a group, you will need a reliable weapon against them.
I hope my reviews will be helpful to you. Not every natural insecticide for roses is helpful, and some chemical insecticides are harmful to flowers. This is why it is vital to find the most suitable remedy against pests. Don’t wait for the heavy infestation; get familiar with my top favorite rose insecticide sprays and powders, and save your roses.
3 Best Insecticides for Roses
Wondering what’s eating my roses? There are numerous insects that can spoil all the fun. However, the most devoted roses’ admirers are slugs, Japanese beetles, thrips, mites, rose leafhoppers, rose scales, aphids, grasshoppers, leafcutting bees, and even caterpillars. Check out these reviews and order the most suitable products.
1. Bonide Concentrate – Best Systemic Insecticide for Roses
During 6 weeks, this insecticide will shield roses in the garden from any insects. You can use it for camellias and azaleas, as well as roses. It protects from aphids, Japanese beetles, mildew, borers, rust, black spots. This treatment is not sprayed. All you need to do is mix the concentrate with the water and pour it around the rose’s base. If you want to get rid of insects on the flowerbeds, you can lightly sprinkle the substance on top.
Bonide is a well-known developer of insecticides and pesticides. You may check out their offers in case you have problems with the pests in your garden. I recommend applying this remedy one more time after a 6 weeks interval. You can repeat this procedure anytime you see little green bugs on roses. Yet, if you have bees in your household, you have to be careful with the insecticide, as it may kill them.

- It kills bees and can’t be used during the pollination period.

Ortho produces tools for insects, weed, and garden disease control.
After 4 weeks are over, I advise you to apply the remedy again. You need to make sure that all the insects are dead or gone. The remedy contains chemicals, and Ortho developers recommend to keep it out of reach of children. It may cause an allergic reaction on sensitive skin. To apply it, shake the bottle and hold the sprayer at a distance of 10 inches from the flower. The surface must be wet. Spray it on the lower and upper leaves and stems.

Among the active ingredients, there are soybean and corn oils. There are also sunflower, coconut, and almond oils. The tool can be used for getting rid of russet mites, two-spotted mites, broad mites, whiteflies, aphids, Downey, and powdery mildew. If you notice white bugs on roses, you can assume that these are whiteflies and use AgroMagen pesticide.
AgroMagen offers its 10 years of experience with this particular pesticide. It has been tested not only on flowers but on fruits and vegetables as well. To get rid of the insects, you have to mix it with the water and pour it on the rose. Repeat the procedure after several weeks.

4. BioAdvanced 502570B — Dual-Action Insect Killer
For those looking for an inexpensive yet effective spray, I recommend BioAdvanced 502570B. It is primarily aimed at killing insects that damage roses, but it is also suitable for treating other flowering plants. This insecticide works well even against adult Japanese beetles and over 40 different pests. The tool belongs to contact insecticides; that is, it kills insects when it gets on them. It is highly resistant to water and sun and remains effective for up to a month after application. However, for heavy infestation, I recommend reapplying the spray every week until the pests are gone.
In the composition, there are Cyfluthrin and Imidacloprid, which affect the nervous system of pests. These ingredients are not very toxic to humans but can harm beneficial insects like bees. You can use it to treat both outdoor and indoor plants, but the procedure should be done outdoors. Flowers absorb the spray pretty quickly (within an hour), after which the insecticide becomes resistant to precipitation and continues to kill insects crawling on roses. I recommend sprinkling the plants fairly generously so that each leaf is completely covered in the product. One bottle (24 fluid ounces) is enough to process more than 30 bushes.
- Remains effective for a long time;
- Is quickly absorbed;
- Cannot be used indoors.
5. Bonide BND024 — Organic Insecticide Concentrate
If you are a supporter of organic gardening, then you have probably heard about the effectiveness of Neem oil. Bonide BND024 is its concentrate, which is highly soluble in water and suitable for the treatment of roses and other ornamental plants, as well as vegetables and fruits. It kills many well-known insects and protects against various diseases like powdery mildew and rust, as it has an antifungal effect. The oil content of this product is about 70%, and one pack of 16 fluid ounces is enough to make 16 gallons of a mixture.
Unlike other chemicals, Neem oil affects pests at a hormonal level disrupting their natural development from larva to adult and not killing them directly. That is why it does not act very quickly, and it will take some time for you to destroy the entire colony with it. The significant advantage of this product is that it is completely safe for humans, mammals, and beneficial insects. Regardless of how strongly your plants are infested, apply oil every two-three weeks, as this insecticide can be washed off by rain and lose its properties when exposed to sunlight. But the treated plants are reliably protected from the emergence of new pests since the product also has a repellent effect.
- Does not kill beneficial insects;
- Large volume;
- Has antifungal and repellent effects.
- Acts slowly.
