Wax Moth Killer

Wax Moth Killer provides a natural way to kill Wax moth grubs that are attacking Beepol Bumblebee colonies. Wax moths normaly lay their eggs on the outside of the Bumblebee colonies often on the wood of the Beepol Villa, they then hatch and move inside the Villa . Wax moths also lay eggs on the exterior of the cardboard outer casing of the Bumblebee colony and develop into grubs there. This is the most common place to find freshly formed grubs, as they often congregate in numbers on the sides of the box. If these grubs are not removed or treated , they will eventually enter the colony interior destroying the bumblebee colony. Wax Moth Killer uses nematodes to kill these grubs.

When to apply Wax Moth Killer nematodes

Apply the nematodes as soon as Wax moth grubs are observed. Do not apply before they are present, as nematodes do not live long in this type of environment. Wax moth activity normally starts in June but maybe earlier in warm conditions. Start monitoring Bumblebee colonies from May for Wax moth activity.


Close the Beepol Bumblebee colony sliding door the night before application to keep the bees inside. Apply the nematodes the folllowing morning.

Mix one sachet of nematodes into a bucket of 2.5 litres of water [ not into freezing water but tepid to avoid shocking the nematodes ] and add to a hand held or knapsack sprayer [ do not apply with a watering can or hose end feeder applicator ] Then add 5.5 litres of water to make 8 litres of solution in your sprayer. Remove any filters from the sprayer and use a coarse or wide nozzle apperture. 

Spray the nematode solution directly onto the Wax Moth Grubs. DO NOT SPRAY THE NEMATODES INTO THE INTERNAL AREA OF COLONY WHERE THE BEES ARE. Apply the nematodes onto the grubs on the outside of the colony, either on the outside of the cardboard outer or the interior wood of the Villa, if the grubs are present there. They are often found down the sides of internal area of the wooden Beepol Villa. Thoroughy spray and re-spray cover the Wax moth grubs with Wax Moth Killer nematode solution to soak the grubs with nematodes. The nematode solution cannot be stored or re-used once it is mixed.

Once nematode spraying is complete , open the Beepol Bumblebee colony sliding door to release the bees, stand back after you have opened the door, as bees maybe aggressive at first.

Once the nematodes are able to enter the grubs, they will start killing them within days. Infected or dying grubs often turn brown.

For severe infestations or new infestations, repeat the treatment.

Keep monitoring the Bumble bee colony for future wax moth attacks and re-apply Wax moth Killer nematodes when required.


Wax Moth Killer nematodes should ideally be applied soon after they are received. However un-opened sachets can be stored in a fridge for several weeks.
