Aphids are a big problem for Crape Myrtles every year and this year is no different. If you have a Crape Myrtle with wet, sticky leaves and tiny white to greenish yellow bugs all over the underside, then you probably have aphids. In this region, aphids primarily affect Crape Myrtles, but have been known to affect Rose of Sharon as well as Roses from time to time.
Aphids are tiny insects that feed on the sap of a plant, and if severely infested, can make it decline in health and keep it from blooming. More severe infestations will actually damage the plant enough that it will not be able to survive a harsh winter. Therefore, it’s important to take care of your aphid problems before they become substantial. The easiest solution is to prevent them.
Preventing aphids is fairly easy. At LawnAmerica, we prevent aphids by performing two applications: one in the spring and one in the summer – using a systemic insecticide that provides excellent results. However, if you missed the first preventative application, we can still treat aphid problems with the same insecticide.
If you prefer a do it yourself approach, Merit Insecticide (active ingredient: Imidacloprid) is readily available at most big-box stores and garden centers. Just remember to read the directions for treating aphids specifically.
Lady bugs are also a common predator of aphids. So if you’re interested in going the more natural route, lady bugs should be in your arsenal – as well as insecticidal soap.
If you are unsure whether or not you have aphids, or for any other landscape related issues that may need attention, give us a call. We’re always happy to help.
