Pesky plant pests

[Corzhens]

Wild pepper grew in 2 places in the backyard. We just let them be and before we know it, they are already fruiting. This morning we noticed holes in the leaves, obviously being attacked by insects. Our only recourse is to spray insecticides to somehow preserve the fruits which would be turning red soon. It is not aphids this time but a certain small insect that lays eggs under the leaves.

What does wild pepper looks like and can you eat it after spraying insecticide on them? I know I buy fruits and vegetables at the market that have insecticide spray on them for consumption, so your might be safe as well.

Many of my plants are eating by Japanese beetles.
