Have silkworms and too many discoid roaches.. I hatched approx. 300 silkworms that are now about 1 month old and 100 large nymphs/adult discoid roaches. My 2.5 month old male ambilobe will not eat the silkworms and I definitely have too many large nymphs soon to be adults discoid roaches. I was hoping to see some baby roaches soon but don't need so many large roaches. What is the best way to down size the roach colony? Anyone interested in silkworms?
