LARGE SIZE

Microbial preventive based on Bacillus thuringiensis aizawai, for protecting stored combs and supers from wax moth.

Wax moth does not attack the store room: it takes advantage of whatever is put away unwatched. B-401 is sprayed onto the combs before you store them, and acts on the larvae when they ingest it.

01 · HIVE HEALTH

It works by ingestion, on the young larva

It is a concentrated solution of Bacillus thuringiensis subspecies aizawai. The larvae take it in as they feed on the comb and stop developing. That defines exactly where it belongs: it acts on the young larva, so it is used preventively — before the comb is infested, not to rescue one that already is.

02 · INSTALLATION

Applied at storage time, not mid-season

The moment is after the harvest, when you take the supers off to store them. It also serves to protect bait hives or empty boxes. Depending on the formulation the effect can hold for several months; check the product's own data sheet for duration, expiry and storage.

03 · HOW TO USE

Dilute to 5 %, spray both faces

Shake the bottle well before mixing. Dilute 1 part B-401 to 19 parts water (5 %): 10 ml of product in 200 ml of water covers 5 Dadant frames, 7 Langstroth, 10 shallow or 5 Layens. Spray both faces of the comb. Once diluted, use it the same day. Let the combs dry somewhere airy before storing, or the damp will give you mould.

04 · WHICH SIZE?

It depends how many combs you are putting away

The sum comes straight from the dose: every 10 ml treats one batch.

120 ml	12 applications — around 60 Dadant frames, 84 Langstroth or 120 shallow.
1 litre	100 applications — around 500 Dadant frames, 700 Langstroth or 1,000 shallow.

05 · BEFORE YOU BUY

What it does not do

It does not replace management: wax moth takes the space the bees are not defending. Matching volume to population, renewing comb and not storing old black comb weigh as much as treating the stored material.

✓ USE IT	On combs and supers, before putting them away.
✕ IT WILL NOT	Rescue a comb that is already infested.
⚠ ONCE DILUTED	Use it the same day.

⚠ PRECAUTIONS

Always follow the product's own data sheet for dose, expiry, storage and conditions of use. Let the combs dry before storing them to avoid mould. And do not treat it as a fix for a weakened colony: it is a preventive for stored material.
