The best insecticide for dahlias is a systemic insecticide. This type of insecticide is absorbed by the plant and carried throughout its tissues, including leaves, stems, and roots. The chemical then spreads to other parts of the plant when it grows new branches or flowers.

The dahlia is a beautiful flower, but it’s also susceptible to a variety of pests and diseases. When you’re growing dahlia plants, it’s important to be proactive about protecting them from pests and diseases. A systemic insecticide will kill insects that feed on dahlias through contact with the plant’s tissue or by eating parts of the plant that have been treated with a systemic insecticide.

Use the Safer Brand Insect Killing Soap

You should also consider Safer Brand Insect Killing Soap. This product is a great choice for dahlias because it’s safe to use on vegetables, fruits, flowers, and trees. It’s also an excellent option for organic gardening. The soap is easy to apply with a spray bottle or hose end sprayer, just be sure to dilute it according to the directions on the label before using it. You can buy this insecticide at many garden centers or online retailers like Amazon.

Use the Bonide Spider Mite Control Concentrate

  • Spray on the undersides of the leaves, which is where spider mites like to hide.
  • Spray the tops of the leaves, too.
  • Also spray on stems and flowers, as well as buds and petals if you see them, and don’t forget to cover those undersides!

Use the Ortho Bug B Gon Garden Insect Killer Spray

Use the Ortho Bug B Gon Garden Insect Killer Spray when you are just starting to see bugs on your dahlias because it works best as a preventative measure. The spray will kill insects on contact and also has a residual effect, which means it will stay on the plant for up to two weeks and continue to kill other pests that walk over it. You can use this product in conjunction with other insecticides, but you should always wait at least 24 hours between applications of different sprays so that they do not interfere with one another’s effectiveness.

To apply Bug B Gon Garden Insect Killer Spray:

  • Shake bottle well before each use; avoid breathing in vapors from the product during application (wear protective gloves if necessary).
  • Apply entire contents of one-gallon container per 100 square feet of infested area(s), starting at the soil surface and working into crowns or clusters of plants until thoroughly wetted; repeat as needed every 3 weeks if heavy infestation persists; may be applied up to 10 times per growing season if needed (always read the label before using). Do not get these chemicals into streams/ponds or onto sidewalks/driveways where pets/children could come into contact with them.
