Moth protection in beeswax

The wax moth (Galleria mellonella and Achroia Galleria) is a pest that feeds on honeycombs and wax residues. Its larvae excavate galleries and destroy frames, affecting both the stored material and the weak hives.

The most common signs are cocoons, galleries in the wax, remains of silk and an unpleasant smell. If when you check frames you see fine threads or dust, there are probably active larvae.

The moth proliferates with heat, moisture and low ventilation. The frames stored without protection or hives weak are their ideal environment. A cool, dry environment significantly reduces the risk.

• Store the frames in places Ventilated, cold and dry.
• Avoid leaving wax residues or honey that attract adult moths.
• Renew old frames and keep the hives strong.

The Freezing (–18 °C for 24 h) removes eggs and larvae. The acetic acid In closed chambers it is also effective. Another ecological option is the use of Bacillus thuringiensis (B401), a safe biological biocide.

If the damage is mild, the affected part may be cut and the rest reused. In extensive damage, it is advisable to melt the wax and disinfect the material to avoid reinfestations.

• Stacking the frames in towers with good ventilation.
• Use cold rooms or apply acetic acid treatment between layers.
• Cover with fine mesh to prevent access to adult moths.

It is recommended to check every 3–4 weeks during the warm months, especially if temperatures exceed 25 °C, since that is when the moth has more activity.
