So gross 🤢 fungus gnats are THE WORST! One adult can lay up to 200 eggs 🫣 so even if you see one flying around you want to make sure you’re treating ALL your plants. These BTI drops contain a bacteria that controls fungus gnat larvae, breaking the cycle. The bacteria lasts for about 1-2 weeks in soil/water/perlite/moss so I’m important to use every watering. One drop is all you need but if you use a little more that’s fine too. It won’t harm humans, pets, fish or birds, and is effective agains
