I get these little flies/gnats/fruit flies every now and then. They tell me here to pour boiling water down my drains to kill the larva that hatch out in the grease ring in the drains and the sink traps. I have lids on my fermenters to allow gas to escape but nothing to get in. I don't think with proper fermentation using cloth to cover the fermenter is necessary, that is the only time I have had something get in that fouled the FF so bad it smelled rotten. Keeping a tight lid on the fermenter has stopped that yet still allows the gas to escape, keeping oxygen out as I understand it is also necessary or the wrong bacteria will be able to live and can spoil the mash.I have a question, I ferment in the house with a 5 gal. bucket with a 2 gal inside of it, with a heavy towel across the top, well I am seeing tiny little flying bugs in the house and this morning when I got the ff up out of the bucket to drain I didn't see any bugs in there but when I took it outside in the dish there they were crawling on the ff, not alot but enough to see, has anyone else had a problem like this, They are the same bugs that were in my compost bucket in the kitchen about a month ago, got rid of them by dumping the bucket of compost and washing out the bucket. Am I destined to have bugs flying in my house with the ff in here?
