Calistrip Biox 6.44 g - 10 strips
Calistrip® Biox – Oxalic Acid Strips Against Varroosis (10 pcs)
Calistrip® Biox is a modern, certified veterinary product designed to control the varroa mite (Varroa destructor). It uses a special matrix with slow release of oxalic acid dihydrate, which provides effective treatment of bee colonies with respect to the natural operation in the hive. The product is approved for use in the EU and is a suitable choice for conventional and organic (BIO) beekeeping – without unnecessary risk to honey quality.

Why You'll Love Calistrip Biox
You'll appreciate the strips wherever you need to treat colonies reliably and without complicated handling. A great advantage is effectiveness less dependent on temperature – the treatment is thus usable even in warmer periods, when some vaporizers can be significantly more aggressive. Thanks to its action for up to 6 weeks, the product helps to target mites gradually emerging from capped brood.
Another benefit is cleanliness of operation in the hive – oxalic acid is among substances naturally occurring in nature and when used correctly, the treatment is gentle. The practical design with flexible stops also allows you to adjust the strip length according to the frame size used (e.g. 39×24, Langstroth, Dadant). The product is available over the counter without a veterinary prescription.
How Calistrip Biox Works in the Hive
The strip is designed for controlled and stable release of the active substance. Oxalic acid remains on the strip surface and bees gradually distribute it throughout the brood area during normal movement, mutual contact and grooming behavior. Best results are usually achieved during periods with less brood, but the product can be used during the season as needed for the colony.
Application and Dosage in Practice
Application is simple even for beginning beekeepers. Hang 2 strips in one hive (in the brood chamber) in the bee spaces between frames, ideally in areas with the highest bee activity. Do not shorten or cut the strips – adjust the length only by bending according to the hive construction. Leave them in the hive for a maximum of 6 weeks.
During treatment, honey supers intended for honey extraction must not be installed. For the best results and to limit reinvasion, we recommend treating all colonies at the apiary simultaneously.
