I thought I had drought damage after the heat spell a few weeks ago. When the yard looked worse after three inches of rain, I took a closer look. Man was I surprised to discover I had a white grub infestation. I hadn’t noticed an unusual amount of June bugs to make me suspect grubs. Then I noticed it was worse under the street light at the curb. (You might want to check your lawn near street lamps and outdoor lights that are on most nights.) After pulling up most of my parkway, I decided to check with the Texas A&M AgriLife Extension Service’s, “Ask a Pro”, for Tarrant County about organic options for grub control. I have been developing an echo-friendly sustainable yard and garden since I moved into our present home, and I sure don’t want to do anything to destroy what I’ve worked so hard to create. I didn’t want to poison the grubs and every other living bug, worm, pollinator, and beneficial insect in my yard with a chemical insecticide.
The expert responded a day latter with several organic methods. He listed finished compost or compost tea, beneficial nematodes, lemon scented dish detergent (1 part detergent to 2 parts water), Bacillus popilliae (milky spore bacteria). I chose to go with the beneficial nematodes because they help control not just grubs, but fire ants, Japanese beetle grubs and a whole host of other detrimental insects without harming earthworms, bees, or other pollinators. He also recommended to apply whichever method by August 20th for optimum results.
I want to thank Steve Chaney, Texas A&M AgriLife Extension Service for his help.
