Beetle Banishers are the safest, easiest, most effective way to eliminate the threat from Small Hive Beetles. They require minimal maintenance, install in seconds and protect for years.

Small Hive Beetles are a scourge afflicting bee hives across most of North America, Central America, and Australia.

The Small Hive Beetle larva decimates hives by devouring the bee brood, bee bread, and honey stores. Their defecation in the honey causes the honey to ferment, seep out of the comb and slime the hive.

Small Hive Beetle infestations can wreak havoc and under certain circumstances are capable of causing even strong colonies to abscond.

Even when colonies manage to keep the beetle population under control the colony’s productivity suffers because many of the worker bees must spend their days keeping the beetles corralled, away from the comb.

How long does it take to clear a hive of beetles?
How long it takes depends on several factors. The most important factor being the amount of sunlight the hive receives during the day. Facing the hive entrance in the general direction of the sunrise or sunset also increases the depth and duration of the light into the hive throughout the course of the day. So far most test hives have been beetle free within 2 weeks.
If the Banisher is set on a hive in full sun, and we have sunny days, is it more effective?
The sunnier the hive location the quicker the Banisher will produce results, but even in partial shade, the Banisher will generally rid a hive of beetles. It simply may take longer. Hives that receive little to no direct sunlight may never become beetle free. In order to use light to effectively evict the beetles the hive must receive sufficient light.
If the bottom board is a screen instead of a solid bottom, will it affect the Banisher’s performance?
There is a direct correlation between the amount, frequency and duration of light inside the hive and the promptness with which the beetles vacate the hive. Theoretically screened bottom boards might encourage the beetles to leave a little sooner. Banishers have been successfully used on hives with solid bottoms, and hives with screened bottoms. The ability of the beetles to access the interior of the hive via a screened bottom board is irrelevant. Regardless of where or how the beetles gain entry they will not like the light.
Where do the beetles go when they are banished from the hive?
It is reasonable to assume that the beetles will migrate to an unprotected hive. However it has been observed that a Beetle Banisher was removed from a hive, once the hive was beetle free, and placed on a neighboring hive, and as the 2nd hive became beetle free the first hive remained beetle free. So exactly what happens with the beetles isn’t 100% clear.
Will the beetles return if the Banisher is removed?
It’s been our experience that hives have remained beetle free for up to 10 days before a few beetles are found in the hive again. But anytime a fresh swarm of beetles arrive at an unprotected hive it will of course become re-infested.
Will the sunlight cause a greenhouse effect inside the hive?
None of the test hives have had any issues with excess heat buildup. As in any exceedingly hot climate proper ventilation of the hive is essential. If a hive is in an exceedingly hot climate, with intense direct sun, a 12″ X 16″ piece of aluminum foil can be centered on the inner panel under the outer cover to create shade in the center to block excess heat.¬† This sill allows a couple of inches of unobstructed light in the hive around the edges where beetles would like to hide.
Won’t the bees propolize the cover preventing it from working and making it difficult to remove from the hive?
The Beetle Banisher consists of two parts, the red outer cover and a clear inner panel. The inner panel prevents the bees from having access to the outer cover. Some bees do propolize the inner panel to the hive but once you remove the outer cover it is easy to loosen the inner panel with a hive tool or knife. So long as there is sufficient crawl space between the inner panel and the tops of the frames the propolis will be pretty much limited to the outer edges.
