You do need to identify those "bugs" so the right control can be applied. Spraying something can create more problems since many products are very broad spectrum and can kill off the beneficials that could aid in controlling any pests that are there.
You alos need to look very closely at the soil these plants are growing in to be sure it is a good and healthy soil that will grow strong and healthy plants that will be less attractive to insect pests.

Could those "small thin beetles" perhaps be earwigs? Google up an image to check. There are various simple mechanical traps that can be rigged and work reasonably well on earwigs.

Maybe earwigs, like mary sez. Until an ID is confirmed, repellents are useless.

I think they are earwigs... they seem to be burrowed in my garden soil. It is 5 year compost soil. So how do I deal with the earwigs?

Many, many recipes for traps on this forum. Vegetable oil, newspaper...whatever you find that suits you.

Dan

wow... there are lots of pages on this forum about those little things. Has anyone tried diatomaceous earth?

DE will have some impact, but it's not as effective as the traps. Read all those posts and rig some traps.

Thanks! I will set those traps tonight!

If what you have are Earwigs there are alos garlic based sprays that you can use to repel them with. Although your garden will smell more like a pizza parlor then a garden those sprays do work.
