Help with parasitic phorid flies

[Kaiko]

Recently I’ve been dealing with phorid flies on my G. portentosa colony. I hate them so much but since they weren’t actually harming my roaches, I didn’t panic THAT much. Yesterday I found a lot of maggots feeding on a deceased roach and when I started cleaning, I noticed a young female with, what seems to be a hole on her abdomen. I start looking for answers and found out that phorid fly larvae can actually parasite roaches. 
 

I am keeping her apart from the rest to watch over her. I’m scared since I don’t know if she’s the only one infected. Any ideas on what should I do? They’re not kept as feeders, but as my precious pets.

hi, gee I dont know, doesn't sound good though. Have you took each one out and cleaned all the areas? They could also be somewhere else in the room.
