it is back
Bad news guys, it is back

My plants grew a lot since then and it seems to like eating from the shaded leafs below, that's why I probably didn't notice new damage,.. I just had an encounter with it, when i opened the tent earlier, I managed even to catch it with my finger against the tank, and pushed hard so I was sure I killed it, but guess what the bastard is so tough as soon as I released the finger flew away and hide somewhere.. I shaked the pots trying to make it come out again,.. nothing. Whf are fungus gnats so tough? Or is it something else. It is about 2 cm in size with a bulky body, white yellowish colour.. I still think it is only one guy, probably I just thought I killed it last time because I slaped it with the palms but I didn't find the body after and knowing now how tough it is I probably didn't. The damage is also not too much just a few leafs here and there, and knowing how insects multiply I should have alot of them by now.. I still tink there is 1 maybe 2 individuals probably not enough to make babies?
In the mean time I ordered a pesticide, just to be safe, but now looking at the bottle I'm not so sure weather I should use it, or make a tobacco / soap thing. It says on the bottle to be used on flowers and decorative plants not edible (nothing abot smokable) however they claim it is natural, even it's name is "Nature's Answer". It also says it should be used away from fish ( this gets me worried about my dogs), also it says not to contaminate drains, and water container, and with my hydro system would be hard to spray it without it driping in the container below and on the drains... I got it from a grow shop howerver and searching for more info online i found that numerous grow and hydro shops sell it,..
View attachment 177814 this is how it looks. Anyone had any experience with it?
I'm thinking if it's only 1 bastard the best would be to just hunt it down and kill it, but how if it is so tough? Encounters with it seem to be rare, and even if I do catch it, I fear it won't kill it again...
What would you guys do?
