How to Treat Japanese Beetles
Japanese beetles can be difficult to control, but it can be done. The only thing is that I hate doing the treatment. That is because the best product to use for Japanese beetles is imidacloprid. This material has the potential to kill bees if it is applied on or under flowering plants. Recent studies suggest that the bees can take this material back to the beehive and share it with the other bees. This can cause the entire beehive to collapse. Obviously, this is not a good thing because we need bees to pollinate plant life. So, before going with the best solution, I would like you to try something else first. If that fails, then go ahead and use imidacloprid. The treatment method is almost exactly the same. The biggest difference is the product that you will be using.
Please watch my video on how to use a 20-gallon hose-end sprayer. Try using Bifen IT first to see if that works. There's a very good chance that this will get it done. Mix the product so that it comes out of the sprayer at 1 ounce per gallon. My video on how to use a 20-gallon hose-end sprayer will explain how to do this. Apply enough of the product on the lawn so that the liquid will reach the soil. You must get the liquid down to the soil line because it does no good just to be on the top of the grass. You also need to spray on and under all the plants that are being attacked by the beetles. Make sure that you treat under the leaf surfaces as well as on top of the leaf surfaces. You want to make sure that the beetles have no choice but to contact the pesticide. Keep in mind that it can take several weeks before you see results. I recommend that you repeat this treatment every 60 days.
If you do not see results within a few weeks, then you need to try using Dominion 2L. The treatment is done the same way, except you need to mix the product so it comes out of the sprayer at 0.6 ounces per gallon of water for the lawn, and about 0.02 ounces per gallon of water to treat the plants. An easy way to get 0.02 ounces per gallon is to put 0.3 ounces in the sprayer and fill it to the top. Again, allow a few weeks for this to be effective. You need to repeat this treatment every 90 days.
