bugs!

i found a burst open kohlrabi in the garden this evening and i buried it with honors...as i was digging a deep enough hole in the bed i discovered a group of asiatic garden beetles in the soil...so they are in places beyond the cherry tree...and am assuming throughout the garden...i don't see a lot of leaf damage around so i am hopeful that they are not so numerous that they actually are a threat...they are nocturnal feeders which eliminates raptors as possible predators...i will be looking for trap crops, natural repellants, and predators to see what can bee= done if we need to begin some serious pest control...there must be something they don't like...or something that likes them...
