Tiny bugs in substrate?

I've recently been noticing these tiny bugs crawling around the sub (coco fiber) in a couple of my T enclosures. There aren't a lot of them, I've only seen one or two at once. They're also not mites, as these move very fast and are more oblong shaped. Taking a photo of one would be impossible.
Has anyone else run into these things? I'm starting to wonder if they came in on some cork bark. I just wanna be sure they're not parasitic or harmful.

Sounds like phorid flies. Theyre tiny oblong critters they look grey or whitish and although they are flies and can fly they normally just scrurry around.

They're definitely not springtails. I'd post a pic but they're way too small and blend in with the sub too much.
The phorid flies match the discription, thanks.

Do you use crickets as feeders? Crickets can lay eggs in the substrate and hatch leaving tiny little crickets. This has happened to me plenty of times.

They could be dermestid beetle larvae. Are they kinda oblong shape & a grey colour, about quarter inch or so long? To my knowledge they do no harm. Some people use these as part of a clean up crew.
Sometimes when I buy crickets from my LPS these are sometimes in the container with the crickets.

Thanks for the replies everyone. From what I can see they have little wings so I'm pretty sure they are phorid flies.

If you have a heat humidifier at home... Set it up next to the enclosures and the phorrid flies fly into it because they love humidity and heat. Then they die because it's too hot and too wet. I had an outbreak a few months ago and my heat humidifier pretty much took care of it in a week or two.

I'll keep that in mind, thanks. I'm not too worried about it just yet. I've only seen one or two at one time. Just wanted to be sure they weren't harmful.

Honestly they are much more of a visually distasteful organism more than anything. Ive managed to get rid of them but was not able to find much hard evidence that they can actually harm a t. In reality i would imagine much worse in the wild in terms of small organisms impacting a ts health. I could be wrong but like i said information was spotty at best regarding them actually doing harm to the t.
