I've noticed many holes on the leaves of my Havasu hot pepper plants. I'm not sure what insect is eating them, and so I was hoping someone knew.
Also, how could I get rid of the insects?

Healthy plants are the best defence when it comes to insects. If you over-water or over-fertilize your plants they become weak and bugs attack them. Keep your soil loose on top with a hand cultivator about a inch or two after each rain. Keep it stirred up as often as you can, and that will give the plants the oxygen they need. Never keep the soil wet because the plants need dry time to be healthy. Be very gentle around the roots and the base of the plant. If you do that, the plants will not have any bug problems and your plants will grow like crazy. Happy gardening.
