Fly removal in potting soil
Who does not know this plague: one has plants in the flat and therefore also a lot of small flies. Now you can remedy that without your plants happening. And best of all: "Everything you need for this you already have at home!"
Fill a nebulizer with lukewarm water, oil, salt and baking soda and spray onto the ground. The process after approx. 10 min. to repeat. After that you can already see that the flies do not like to stay there anymore. It is best to open windows so that the flies can disappear.
I tried this on 20 banana plants and I'm thrilled.
