Japanese Beetles In St. Louis

Have you seen Japanese beetles around your home in St. Louis as of late?  I know I have.  They love to eat the leaves of my banana trees and elephant ear plants.  But I am luckier than some people because my infestations tend to be on the low side and I can easily keep them in check by picking them off the plants and throw them into a water bottle filled with soapy water.  The soapy water doesn’t allow for surface tension and the beetle easily drowns once it is in the water.

Controlling heavy infestations can be difficult due to our inability to reach tall growth were they may be feeding.  And to top it off, whatever we control one day, we could wake up to a whole new infestation (and possibly a bigger one than the day before).  Because Japanese beetles start off as grubs, it is possible to kill a good portion off in spring before they emerge if you treat your yard with a grub killer.  The bad news is, just controlling grubs in your yard will not keep them from flying over from a neighbors lawn and onto your plants.

So what kind of treatment works best? Any treatment that will allow you to apply a pesticide to those favored feeding sites.  They do make pesticides containers that you can attach to the end of your hose and most of those would control Japanese beetles, but the problem you may have is that it will not allow you to treat higher than 10-15′ in the air.  And as most of know, infestations in some ornamental trees can be must higher than that.

The best treatment option for Japanese beetles is to hire a professional company that can utilize a back pack mist fogger to blow material up and into the high foliage around your home.  Now you may be wondering if this treatment is fool proof? And the answer is no.  Will it greatly reduce any future damage to the plant? Yes.  But the longer you wait to control them, the more damage that can be done.  And in some extreme case, your plant may never recover.
