Fungus gnat on seedling media

Better not use hydrogen peroxide. Maybe put one of those automatic puff sprayers (pyrethrum spray) that puffs some pyrethrum into the air every hour or so ----- to ward them off.

Or use some 'mosquito dunks' solution.

Thank you. Unfortunately, due to my sensitive skin and breathing issues, i have to avoid "toxic" chemicals. The plants are now placed in my bedroom with proper lighting.

If chemicals are the only way to treat this situition, i guess i have to give them up to some other orchid lover
