Did I jump the gun when I used safers brand diatomaceous earth?

What's up fellas! Well heres the deal I have two lady friends living in my closet each are about 3 weeks into flowering I have noticed more and more little gnats showing up in my room. I only recently realized that I have a large population of fungus gnats thriving in my closet so I ran to lowes and got some diatomaceous earth to sprinkle ontop of my soil to get rid of these little bastards and in my haste I didnt read the label very well and I think I could have screwed the pooch on this one... the problem I have is that the product I got has about 22% "other ingredients" and now i'm just pissed...This is what I want to know...
Has anyone else used this particular brand (safers brand) of diatomaceous earth without hurting the plant?

what are my options as far as a remedy for my error if it turns out to be a bad thing?

If its not harmfull then what should I do about watering? do I need to re-apply more DE after I water?
Any input would be great...kiss-ass

I have used it before and I just reapplied the day after watering because water renders it useless. The gnats were free with a bag of Fox Farm Ocean Forest. lol I ended up double bagging my soil and let it cook in the sun for a couple days. So far no gnats on this grow.
Also the sticky traps help keep populations down. I had a few that got caught in the bud resin and i just picked em out at harvest. Smoked very well.

I am a fungus gnat killing machine. DE works too slowly in my opinion. It slowly eats away at the larvae/ pupae's exoskeloton n dehydrated them until victory. I watered once with it on top but it looks nasty afterwards but did no harm to the plants. DE is very organic and 100 % non toxic - but it is recomended not to breathe in the dust as it has very small particles that are not good for your lungs, just like anything else that's not air your breathing in. I wud try to scoop the top layer off before watering just in case over prolonged usage.
Some people use neem oil and dish soap to kill em - probably the most popular and effective.
How I wiped out about a thousand if them in 3 days - put priority mail packaging tape on a flourescent tube and put it on the soil/ pots. The gnats are attracted to the blue flourescent tape and land/ crawl on it and die. To kill larvae just let the soil dry out a little more than usual to avoid growing the fungus they thrive on.

Nice. I did the opposite n put the soil out in the winter for a few days. A nice gnat genocide to start the grow off.

A good way to avoid the fungus which gnats develop in is to rake the surface of the soil with fingers to the depth of first knuckle just before each watering. This also helps aerate the surface for better absorption. Do this every time and you will never see a gnat.

Also can rake the soil a day or 2 after watering to let it dry out better, the larvae live in the top couple inches of the soil

Cool, thanks guys this really put my mind to rest...

This stuff works great btw... no more gnats in about 5 days.
