The warmest place in the house is the toilet and TH put all his plants inside it and there are these tiny flies everywhere. Which is annoying me obviously… the neem or whatever that chemical is called do not work. So i asked TH to find a solution or remove his plantings…. And he bought Nematodes( from amazon) which you hatch them and they grow and start eating fungus gnat larva inside out…. (See video- the bigger snake like worm feeding on the smaller worms…which will turn into the flies) The eggs are commonly found inside soil so TH find this way is the best… . Anyway, u can‘t see the worms…. He caught 3 and put it under the microscope…. To watch it in action…. I am not sure how many x zoom…. #pestcontrol
