Bee hotels — boxes promoted as good nesting places. “Bee-friendly” farming techniques behind favorite foods.
Are the claims true — or just honey-drenched hype? Lila Westreich, a bee researcher at the University of Washington, says companies take advantage of well-intentioned consumers by “bee-washing.”
The term, first coined by researchers in 2015, refers to greenwashing, in this case a marketing strategy that makes a product or practice seem beneficial to threatened bees. (Greenwashing evolved from the term whitewashing and means an environmental spin.) In The Conversation, Westreich writes that the practice can actually hurt bees.
Bee hotels are advertised as safe nests for bees, for example, but some may be dangerous. The welfare of honeybees may be overemphasized, misleading the public about environmental priorities.
Wild native bees are at particular risk. Of the 20,000 or so bee species in the world, only about 4,000 are native to North America — the bumblebee among them. These bees don’t produce honey, and they’re less sociable and well-known than their so-sweet counterparts.
The majority of American bees don’t produce honey. Honey bees came to the United States from Europe. Kelsey K. Graham, another bee researcher, calls them the “chickens of the bee world” because they are so domesticated.
Unlike hive-dwelling honeybees, which are carefully bred, imported to the country for use in crop pollination and managed, the majority of native bees are solitary and nest underground. They reportedly pollinate up to 80 percent of plants, including many crops.
They’re also at risk: In a 2017 study, the Center for Biological Diversity found that more than 50 percent of North American native bee species are declining; 24 percent are threatened with extinction.
Native bees are threatened by climate change, habitat depletion and pesticide use — but honey bees get most of the publicity.
“While many people are worried about honey bees, it’s also important to understand the jeopardy that native bees face,” Westreich writes. “Companies and organizations use bee-washing to boost their image, taking advantage of the public’s lack of knowledge of native bees.”
By bragging about how they help honey bees, notes Westreich, they play down the importance of native species that, unlike honey bees, are actually endangered. They also play up their solutions, such as bee hotels, that can hurt bees by spreading disease.

Climate change could increase bumble bees’ extinction risk as temperatures and precipitation begin to exceed
species’ historically observed tolerances. A new study adds to a growing body of evidence for alarming, widespread losses of biodiversity and for rates of global change that now exceed the critical limits of ecosystem resilience.

Commercial pumpkin growers routinely rent honey bees so they have enough insects to pollinate their crops, but a new study published in the Journal of Economic Entomology suggests that wild bees can do the job for free. The three-year study found that wild bumble bees and squash bees could easily handle the pollination required to produce a full yield of pumpkins in all of the tested commercial fields, according to Carley McGrady, the lead author of the study.
The pumpkin study was part of a broader initiative, called the Integrated Crop Pollination Project, or Project ICP (http://icpbees.org/), which was headquartered at Michigan State University and funded by the U.S. Department of Agriculture’s Specialty Crop Research Initiative.
