..hey bud-- sticky traps will not solve the problem- reproduction is in the soil, and that's where you hammer them!... vinegar-- ditto; no peroxide!! that'll f' your soil herd (microbes) up totally :slaps:... another product with identical active ingredients to Gnat-trol are mosquito dunks, used for ponds; you can get them in a granular form too, besides the pucks, and for far cheaper,... local stores/garden centers/pet stores likely will have them (call around).... I use the granular one, otherwise you have the break the pucks up into bits; i like to get the bacteria started fast by mixing up a gallon of non-chlorinated water with 1T molasses or brown sugar and a dash of plant nutes, then add the dunk stuff, and let it sit for a day, then water normally,... it'll take a few days, but once ingested they're doomed!.... good! look up a pic of soil gnats, and scope one of them out with the mag'....ID is easy that way,...
