Fungus gnats

Are fungus gnats harmful to tarantulas? We recently had a fight with them in our house plants and I assume some may have found their way into my ts substrate. Should I worry?

The enclosure is only lightly misted once a week since it's a B.hamorii the gnats were originally in some house plants we got. I'm not sure they are in the enclosure. Just wanted to act preemptively if they are harmful to tarantulas

From what I read the adult gnats don't bite so they wouldn't pose a huge problem. Babies (or whatever you call them) might pose a problem if they got on your spider. I am not an expert by any means but I would guess the babies would be in the plants and as long as the spiders aren't kept really close you should be good. If you do find gnats in your enclosure just wash it and change the substrate. This problem is way more prevalent in bio active enclosures or with theraphosa species that need to be kept damp.

Take this with a grain of salt though...I read some posts about it from the guy who wrote the tarantula keepers guide. I have not encountered this before so I have no real world experience in this matter.

Stop misting...they lay their eggs in the moist substate. Let it dry out for a while and they will disappear.

They sell a product that is volcanic glass to put on your plant...looks like perlite. It actually cuts the reproductive organs somehow on the gnats and they cant breed anymore.

No...dont put it in with your tarantulas. It's glass. It sounded like you had house plants. It's not poison...its glass so it cuts up the gnats trying to get to the moist soil. It destroys their reproductive parts. For Your enclosures just dry out and move your water dishes to a dry spot and dont over fill your dishes for a while.

@Arachnoclown is it like this?

cant see volcanic 'glass' in amazon search (in UK anyway)

Can it be in the same room if for example a really damp tray was set up with this stuff to stop the egg laying cycle?

No...they use to use volcanic glass but I think its recycled glass now.
Heres what I use in my house and out in my planters on my patio. It has awesome drainage.
