Hanging clothes outdoors is a very common custom, especially on warm, sunny days. However, more than one person has been surprised to see bees perching on freshly washed garments, and even hovering underwear or towels as if they were flowers.
Although it may cause concern, this behavior has a completely natural explanation.
Bees rely on their sense of smell to find food and find their way around flowers. Therefore, any nectar-like aroma can catch their attention.
Freshly washed clothes usually retain fragrances of detergents and fabric softeners, many of them with floral or fruity notes. To a bee, these smells can resemble the perfume of a flower in full opening.
Therefore, it is not uncommon for them to land on the garments as if they were exploring a possible nectar resource.
The role of colors and sunlight
In addition to smell, eyesight also plays a role. Bees show a preference for light or bright colors that, from a distance, can remind them of petals or pollen-rich surfaces.
When clothes hang in the sun, the light intensifies these colors and makes them more striking, reinforcing confusion. The combination of light tones, sunlight and fragrances is very attractive to these insects.
