The best defense in fighting Japanese Beetles is knowledge. The best strategy in eliminating, or at least reducing the damage done by Japanese Beetles, is through learning the life cycle and applying control measures at the appropriate times. Here we are at the end of June. Are you prepared and ready?
Japanese Beetles will come out of the ground and will fly around and eat on plants for about 30 to 45 days. Here are some ideas as to what you can do to eliminate or reduce plant damage:
Be diligent with some or all of these steps this summer and your effort will go a long way in reducing future generations of beetles.
Here is the next step for control: Come September you want to apply a product called MILKY SPORE to the soil. Any Japanese Beetle eggs laid in the soil will pupate into larvae stag which is the white grub worm. While this larvae is on the top of the soil, the larvae will ingest the milky spore and die, and, at the same time will help multiply the amount of Milky Spore in the soil for even more control. Milky Spore is a very environmentally friendly product. Your strategy is to have the Milky Spore kill as many of these grubs in September before they go down deep into our soil for the cold winter months.
The third step for control of the Japanese Beetle population occurs in February or early March. You will want to reapply Milky Spore for further control of the white grub worm. When our soil begins to warm, the white grub worm works its way to the surface and feeds on grassroots, thus damaging our turf.
In a nutshell, your strategy for control of Japanese Beetles starts with hand picking. Place beetle traps in remote areas. Spray the adult beetle with an effective spray. And, put down Milky Spore in September and again in late February / early March.
