Try this
It is most likely the Japanese Bettle as they are in every garden you will see the holes in you plants and veggies
In 1 cup of water add
1 teaspoon of dish soap (I use sunlight) any will do
I teaspoon of hot chill sauce
1 teaspoon of any veg oil as a coat
Pour into a spray bottle and spray late day or evening for best results--- anytime if you are busy
Theyt do not like the taste of this little recipie
Bettle traps are $12 a piece and not as effictive
Hope this helps you
