Beeswax foundations

Save your bees up to 20 kg of honey for every kilo of foundation you provide

🌿 Replacing comb is hygiene, not just tidiness

A blackened brood comb that has reared 13-15 generations of bees holds barely 46 % actual wax: the rest is larval excrement, pupal skins and propolis residue. Cells shrink, the bees that emerge are smaller and less productive, and the wax accumulates lipophilic residues from varroacide treatments along with spores of diseases such as American foulbrood, chalkbrood and nosema. The rule of thumb is straightforward: replace 20-30 % of your brood combs every year to cut spore load, lower chemical residues and keep your bees healthy and full-sized.

📐 Quick guide: choosing your foundation

Rigid or flexible wax: In warmer climates, rigid foundation holds its shape and prevents the sheets from warping inside the hive during hot spells. In cooler regions, flexible foundation is easier to handle without cracking in low temperatures.

Standard cell size (5.4 mm): The optimal, tried-and-tested size for the European honey bee. Small-cell foundation (4.9 mm) was once promoted as a varroa control method, but peer-reviewed research has ruled that out: it does not reduce mite levels and may actually increase them.

Drone foundation (7.0 mm): Larger cells designed for drone rearing. Essential for queen breeders saturating mating areas and an effective biotechnical varroa control tool: the mite preferentially enters drone brood, so removing and melting down the sealed drone comb removes a substantial number of mites without chemicals.

⚠️ Wax purity is non-negotiable

Foundation adulterated with paraffin, stearic acid or palmitic acid has been shown to cause sealed-brood mortality of 49 to 71 %. Likewise, wax carrying acaricide residues above 100 ppb compromises the bees' immune system and shortens their lifespan by up to 30 %. We only supply 100 % pure beeswax foundation. And if you practise organic beekeeping or simply want the highest health guarantee, we also stock certified organic (BIO) foundation with residue levels below 0.5 mg/kg.

💡 Fitting: embedding foundation into the frame

To fix the sheet onto the frame wires you can use a traditional spur embedder heated over a flame, but the fastest and most reliable method is a 12 V or 24 V wiring transformer: connect the terminals to each end of the wire, the resistance gently melts the wax and the sheet is bonded in seconds, ready to withstand extraction. You will find both accessories in our frame assembly tools section.
