byFormica® Liquid Feeder MICRO 1ml (16pc)

I really can't understate the value of giving your ants sugar 24/7. They have food at all times, will grow faster, and more consistently than colonies given sugar intermittently. If you're worried about how much sugar you need for your ants, this is your solution.
Let your ants tell you how much they need by themselves :)
