Ugh! Gnats/fruit flies/fingus gnats all over my plants and soil.
Comments (43)Not a pro here, but if this helps, here's my fruit fly experience; I took up vermiculture (worm composting), following online instructions. The instructions indicated to have them live in newspaper shreddings, I don't know if that worked for anyone else, but for us it began a fruit fly issue that did spread into some of our houseplants. For one thing we hadn't sterilized the worm castings before using them, that was a definite thing that allowed the fruit flies to spread to the plants. Google search some safe ways of sterilizing compost and soil that you think might have parasite eggs in it. But to get the fruit flies out of my worm castings, I changed the system. I brought in a bucket of sand and a bucket of old dried out clay/dirt from outside, and every time I added a bucket of plant waste to the mix, I'd bury it in the surroundings, then put a fine layer of dirt and then a finer layer of sand on top of all of the mix. That made it apparently entirely uninhabitable for the fruit flies. My theory is that to lay and incubate eggs, they need specifically the surface to be moist and rotten, I don't think they do a lot of burrowing, I'm guessing their wings would get damaged. So regardless of how organic the compost underneath is, they couldn't use it as a breeding ground so long as there was a barrier of dry sand and old clay-heavy soil. After figuring that out, I always pot my plants with a drier, older, nutrient parched soil for the top couple of centimeters. Haven't had the fruit fly issue since. Sorry if that wasn't concise!

Comments (94)Here's my two cents. Idk what it is but like everyone else it's around the sink window/sink and counter top. Sometime I won't see one for weeks then other time like everyday. I have noticed they like white such as white paper towel or white note pads. I've lived in this house for 20 yrs and never had this problem. Not sure but I received a small box from Amazon and I opened it on the counter top(not a smart move) and as I pulled whatever I had ordered out of the box I noticed small spots in the box moving so realizing they were some sort of insect I tossed the box in the garbage but when I picked it up some had gotten out of the box and spread out. I killed what I could and called Amazon and they like said "Duh" so anyway I'm not sure if that's how I got them or are they coming in my sink window.

Comments (18)Hi! thanks for that Texas A&M link. it's got some useful information. Ok, its been about a month since I first posted my request for help, so here's an update on my bin and fungus gnat problem: -the BEST thing I did came from a suggestion from a non-worming friend who suggested mosquito netting. So, I made an "envelope" out of a 4'x6' piece of mosquito netting--I just folded it in half and sewed up the sides, put the whole bin inside and tied the top shut. That way, while I 'm doing battle with the fungus gnats, noone else in the house is bothered by the little critters. Plus, I KNOW the gnats didn't come in with the food--they must have been visiting my basement and happened upon the very inviting habitat of my worm bin and decided to take up residence. This way, the mosquito netting keeps gnats that are outside the bin, out (while it keeps the ones that are already in,in). -I put fairly big drainage holes in the bottom of the bin, since I think most of my issues with the worms have come from it being too wet. -I'm using BT--(Knock out gnats from Gardens alive). It kills the larvae. It says you need to do 3 applications, each a week apart. I'm on application #4 and I still have some adults, but it's much better than before.(I had had a really bad infestation). Since you have to drench the bin with the BT, the drainage holes are REALLY important. -I add lots of dry shredded newpaper each time I do a treatment. It helps get rid of some of the extra moisture in the bin. I take out the old wet newspaper and replace it with dry paper each time I open the bin.Since its so wet in there, I do have little white mites, but they're not too bad. -I made stick traps out of old toilet paper rolls and white (or yellow) fly paper (not the super sticky stuff, that's too messy, but the moderately sticky stuff that comes on a long roll.) I cut the tubes in half and staple 2 together to make a nice solid base, thhn I wrap them with the sticky paper. I put a couple ot these on the top of the lid of the bin (outside the bin, but inside the mosquito netting). They catch a fair number of gnats and let me monitor my success in the gnat-war. -I'm messing with the worms less. This is a bit of a bummer, since I liked frequently checking on their progress, but with the mosquito netting in place, spontaneous visits are a little more difficult. But the worms are happy, happy, happy. Very busy munching large quantities of food. -I'm willing to do one more BT treatment, and then I'm going to pull out the big guns. I have a no pest strip that I really don't want to use, since its so toxic, but I will if I still have adults after the next treatment. -when I feed the worms or do a BT treatment, I use a small vacuum to suck up fungus gnat stragglers. It's a pretty rewarding sport. Ok, that's probably more than ANY of you wanted to know, but I thought since you were all so good about providing suggestions, you needed to know the current status. Have a good weekend! slego...See MoreBought used WF 360 - gnat infested - HELP
Comments (36)Wow just read the whole thread... it was a fun read, so sorry I missed out on all the fun. Each fall when we bring in plants from outside we risk bringing in fungus gnats for the winter... its one of the reasons we've been slowly switching away from peat moss based soil-less potting mixes to using more actual soil and some coir (to lighten it up a little). A couple of winters back, amidst a gnat plague in the house, I found a product online that specifically claimed to get rid of fungus gnats naturally. It is a sponge filled with a particular nematode (thousands of them actually, or so they claim) that target gnat larva and being very tiny they burrow into the larva and ...well you know. The trick is to get it shipped fast and not exposed to weather extremes either during the trip to your house or during storage... you don't want them to die before you get a chance to used them. I ordered fresh from the "manufacturer" to take care of any possible storage issues and timed it with the weather forecasts so it would ship during moderate temperatures in route and got it, I believe, in 2 days transit time. The stuff is not cheap... so I used one of the sponges and put the other in the fridge. I soaked the sponge in lukewarm de-chlorinated water and squeezed it out several times. You can't actually see the little buggers, so this is really all being done based upon pure faith... makes one sort of feel foolish at times wondering if it's all just a scam (ala "the emperor's new clothes")... then I watered all the plants with this water containing invisible nematodes. Anyway, in a week the numbers of flying gnats in the house really dramatically decreased... in another week I was convinced the gnat larva were definitely being controlled but was it 100%?... down to the very last larva?? Can't say for sure if it did completely resolved down to that last gnat larva because by the end of the month it was time to move the plants back outdoors for the late spring and summer so that stray one or two adults seen flitting in the house could have been from a straggler larva population that escaped the wrath of the invisible nematodes... don't know? theparsley... Just a thought here... is it possible the netting isn't what actually solved your problem? perhaps it could have been your own 'invisible nematode' population finally balanced out the fungus gnat larva population? Anyway I believe one of my bins may also have a fungus gnat problem, so we just put it out into the garage yesterday where the temps fluctuate between 32 and 50F all winter long. The worms don't seem to have an issue with this so... we shall see if the fungus gnats can survive it as well. I'm betting not....See Morehuntszoo
