Top box the strips can hang down through to the bottom box.This discussion has been had many times. Don’t over think it, FOB = frames of bees. More than 5 frames use two strips per box. If the colony is expanding into the second  brood box add two strips (remember a frame of brood when emerged will cover at least two frames. Or be prepared to add extra strips as the colony expands.Location, location, location! Place the strips in the centre of the brood nest, where the most contact is made. The chemical is spread throughout the colony via bees that have contacted the strips. Move the strips if the brood nest moves. Sometimes, especially early spring colonies can reduce in size due to die off of older bees and a strip can end up swinging in mid air with no contact with the colony. Or the colony simply move away from a strip.Regular inspection is important- every 2-3 weeks would see you have 3-4 inspections before strips are removed.Apivar is a 10 week treatment in New Zealand. Don’t be surprised if your colony fails if you remove strips at 6 weeks.</blockquote>
