I had a huge issue with fungus gnats with new substrate that I obtained a while ago. However, I changed the substrate to a batch consisting of the same stuff and heat treated it like no tomorrow. The gnat infestation was eradicated. Time goes by with no sight of fungus gnats in the containers whatsoever. However, while sitting in my HVAC class I frequently notice a fungus gnat flying around me. I see it circle around to the front of the classroom and shows no interest in anybody but comes in my direction trying to land on me. I then catch it and slam it on the table. This happened at least three times in a week in the dead of winter which makes me extremely confused. To make things weirder, I was on the computer in my room and notice one fungus gnat zooming past me only to land on my lamp. This is when I am frazzled and then check all of my larvae containers only to find out there is not one fungus gnat when before, I would have ran into at least 4 per container. I checked my two enclosures housing my Dynastinae imago with heat treated organic soil and there was no trace of anything. The only thing I can think about is the plants inside my house and the fact that I wear cologne called "BOD" that maybe they would be attracted to? I look up my problem on the internet and cannot find anything that answers what is going wrong with me. I feel like I am going crazy and am very paranoid. Please help!
