culling cleanup crews (alt. title "Beetle Trap?")

bwhatch2

First Instar
I use what I am pretty sure are a. diaperinus (lesser meal worms) as clean up crews in many of my roach colonies. if you use them you know they can quickly out produce the roaches and need to be culled. has anybody come up with some sort of bait or trap for them to weed them out of the colony. I have mosly used a brute force method of collecting all roaches and sifting them out but this definitely cause so die offs in my colonies.

has anybody came up with a better way ?
