I have fruit nats, in my kitchen and bathroom, they seem to go to wate

To control the ones you have, place apple cider vinegar in a small bowl, they will attract to that and drown in it. You'll have to dispose of it once it catches some and refill. Do a thorough cleaning of both rooms to make sure of any areas attracting them. In the kitchen, clean your drains with drain cleaner or even by pouring baking soda down them and then vinegar to clean them out in case they are being attracted to food matter in the drain.

Remove the fruit from open air

Clean walls that have scented soaps/sprays

Need to do some serious cleaning to make sure they don't have any food.

The vinegar trap in the covered glass jar a cup has always worked for me.

Per link below

“Get Rid of Fruitflies with a Homemade Fruit Fly Trap. Pour just enough cider vinegar to cover the bottom of the jar. Add a drop of dish soap (it will break the surface tension of the vinegar so the fruit flies can't just sit atop the liquid). Now, cover the jar with plastic wrap and poke a few holes in the top.”

The easiest way, and surest way to get rid of fruit gnats is to use Simple Green. You can get it wherever soaps are sold except in Walmart it is in the boat/auto section for some reason. Menards sells it in both concentrate and spray bottles. (I keep both on hand to refill from the concentrate and save money). INSTRUCTS: spray your drains 2 or 3 squirts every day for a week to ten days. That means the shower, tub, every sink, etc. They live in the drains. Then after you no longer see them, spray each drain the same way once a week to keep them down. They come in on the fruit you buy, so be sure to keep fruit in the fridge or a container. Hope this helps. and by the way, it is a great cleaner disinfectant/deodorizer. I use it for all my cleaning because it is not toxic to people!
