you can feed them with a cockroach for protein. and white bread for carbo. hope this helps. i got three pharoah ant queens this morning. they are moving to another site, maybe they are disturbed in their old site. and this morning also, i also got yellow crazy ant queen. under the pile of old wet wood shavings. its bit humid that morning, maybe thats the cause of their showing up.
