Shade and rain cover: enough without going too far

After ants, the two things that kill colonies fastest in this climate are midday sun and rain driving into the entrance. Both are solved by one well-placed cover — and both are made worse by a badly placed one.

Why midday sun is dangerous

The wax stingless bees build with is blended with plant resin and softens at high temperature. A box in direct midday sun can get hot enough that honey pots slump and the nest structure collapses. When that happens there is nothing to rescue; the colony leaves. This is the kind of loss that happens in a single afternoon.

Shade done properly

Natural tree canopy is best: cool and still ventilated. Without a tree, build a roof at least ten centimetres above the lid so an air gap forms. A sheet resting directly on the box conducts heat straight in and is worse than no roof. Metal sheeting needs either an insulating layer or a light-coloured finish.

Rain cover

The roof should overhang the entrance by about twenty centimetres so rain cannot drive in. Water entering the entrance stops bees moving and dampens the nest immediately behind it. Slope the roof so runoff falls behind or to the side, never straight down in front of the entrance.

Where cover becomes too much

Wrapping the box in tarpaulin or enclosing all four sides is a mistake. The colony needs airflow and needs indirect light to orient to its entrance. Full enclosure traps moisture, grows mould, and makes it harder for bees to find their way home.

Check after the first big storm

The first heavy rain of the year tells you whether the cover works: is water driving into the entrance, is the stand flooding, did wind lift the roof. Fix it then rather than after the second storm.

Frequently asked

Can I pour water on the box to cool it?

No. A sudden temperature change and a damp box do more harm than the heat. Add shade and improve airflow instead.

How do I know if a box is too hot?

Touch the top at midday. If it is too hot to keep your hand on, it needs more shade. Bees clustering outside the entrance at midday is the same signal.

Is shade still needed in the wet season?

Yes, because hot days come between the rains. Leave the cover in place year round and only adjust the overhang for wind direction.
