How to Get Rid of Bugs on Coreopsis

by Amanda Flanigan

Also called tickseed, coreopsis (Coreopsis spp.) is a perennial flower growing in U.S. Department of Agriculture plant hardiness zones 4 through 10. These brightly colored flowers produce daisy-like blooms and are generally low maintenance. They can, however, attract various bugs that feed on the sap, leaves, stems and blooms. Though the plant normally is not troubled much by pests, aphids, mites, cucumber beetles and plant bugs can sometimes be a problem. Thankfully, you can control these bugs yourself using readily available insecticides.

1. Aphids, Mites and other Sap-sucking Insects

1 Pour 1 gallon of clean, soft water into a large bucket. Add 5 tablespoons of insecticidal soap concentrate and stir for a few seconds.

2. Aphids, Mites and other Sap-sucking Insects

2 Transfer the solution carefully into a clean garden sprayer. Spray the plants thoroughly with the diluted insecticide until the leaves, stems and buds are covered.

3. Aphids, Mites and other Sap-sucking Insects

3 Repeat the treatment at seven- to 14-day intervals with a fresh solution until the sap-sucking pests are no longer a problem.

4. Beetles, Plant Bugs and Caterpillars

1 Pour 1.5 fluid ounces of a carbaryl insecticide inside a bucket filled with 1 gallon of water. Stir thoroughly for several seconds.

5. Beetles, Plant Bugs and Caterpillars

2 Fill a garden sprayer carefully with the solution. Spray the lower and upper leaf surfaces and stems of the tickseed plant with the diluted carbaryl insecticide.

6. Beetles, Plant Bugs and Caterpillars

3 Repeat as needed up to four times a year.
