High quality fruit fly food with an anti-mould agent in 100mm x 53mm large plastic specimen tubes. Each ready-made media vial comes with a foam stopper a plastic ladder and a sachet of baker's yeast. These vials contain approximately 4x the quantity of media to the small media tubes we offer.
To ensure freshness, all media tubes are prepared to order at our lab in Shropshire. Before adding flies sprinkle a little of the included yeast into the tube and insert the ladder. Tubes are sent with a fitted plastic lid to increase the longevity of the media, once flies have been added, replace lid with cotton wool stopper to allow air exchange. We recommend storing in the fridge until use and adding the flies within 1 week of receipt.
