Will adding coffee grounds to plants attract cockroaches?

It is close to the season for growing veggies over here and I have been looking at amendments I can add to soil to help my plants.

One highly recommended thing I see here is to use coffee grounds.

My only concern is, I have read that a way to kill those large cockroaches (which we have here) is to add coffee grounds and some water in a glass jar and place it by a wall so the cockroaches crawl in and drown.

Has anyone ended up with attracting cockroaches by adding used coffee grounds to their gardens?

Never have seen a problem and I use coffee grounds inside, outside, and in the greenhouse.

RE: Will adding coffee grounds to plants attract cockroaches?

Cockroaches are omnivores, they eat anything and everything, so if they are around they probably would eat the coffee grounds as well as any other decaying organic matter. If the environment is one they like, a source of food and moisture and sufficiently warm, they will be there. Like many other insects outside of the house they are not real problems. SoTX probably has them around.

Coffee grounds wouldn't be any more attractive than other organic matter. We have them here, too. They were in the yard before I started making new gardening beds so the issue of attracting them to a location where they already are is a moot point. You can't garden successfully without adding organic matter to the soil and unless you remove all of it, roaches will come and eat it if they want to. On the upside, roaches are food for lizards, toads, birds. Just another part of the food chain.
