Japanese beetle grubs are best controlled by spraying beneficial nematodes on the lawn and garden area. These microscopic worm-like creatures attack only the grubs in the soil and not plants, animals or humans. Spray them in spring when the soil temerpatures are above 55F and you should see a difference this summer. It's important to maintain soil moisture to keep the nematodes viable and so they can move easily through the soil. I suggest that you moisten soil well the day before you apply them, or wait until after it rains. After application, apply mulch to the soil to keep it moist. You can buy the beneficial nematodes from Gardens Alive, [email protected]; ph# 812/537-8650. |
