Aphids are tiny, oblong insects with different colors, including white. By sucking the sap from the plants with their lengthy, straw-like mouthparts, these insects harm petunias. Small infestations usually don’t harm much or need to be treated.

Spray the entire plant, not just the areas where mealybugs may be seen. Spray stems, top, and undersides of leaves well.

What do petunia aphids look like?
You probably have an aphid infestation if you observe little green bugs on your petunias. Aphids are little, pear-shaped insects that are typically less than 1/8-inch long. Most aphids lack wings and are green to yellow-green in color. However, large insect populations on a single petunia develop wings and fly to other plants.

Apply insecticidal soap sprays to treat severe infestations on petunia plants since they are less harmful than chemical products and only kill upon direct contact, according to Oregon State University Extension. Thoroughly mist the plant, paying careful attention to the undersides of the leaves. Apply the sprays again as necessary because they lose their effectiveness after drying.
Tip
As a healthy plant is less prone to aphid attack, give your petunias adequate amounts of sunlight and water. Avoid using too much fertilizer because the plant will attract additional aphids with lush, fresh growth. A fertilizer with a temporal release that nourishes the plant gradually is frequently beneficial.
What do petunia mites resemble?
Spider mites, small, eight-legged relatives of spiders that resemble tiny, moving dots to the unaided eye, are a common pest of petunias. The first sign of mite feeding damage is a mild stippling on leaves; after that, the leaves turn golden, then yellow or red, and finally, they fall off the plant. On the leaves, you might also spot fine webbing.
How are thrips on petunias treated?
Thrips can be captured using yellow sticky traps, which keeps them from harming petunia plants. Western flower thrips are frequently caught with blue sticky traps, however because of their deeper appearance, they are more challenging to utilize. By feeding on the destructive pests, predatory thrips or mites can aid in the control of a thrip infestation. To stop thrips from spreading to good tissues and other petunia plants, prune the plant’s damaged or diseased regions. Thrips in your garden might also be controlled by row coverings and reflecting mulch. Although it occasionally works well in the short term, horticultural oil typically doesn’t provide a long-term solution.
