Biology and Habits

Mason bees are a group of small solitary bees that are often mistaken for honey bees. They are one of the first species to emerge in early spring to search for small, tubular openings such as straw and plant shoots to make their nest. Females create cells within the tube and provision each one with pollen. Mason bees are highly efficient pollinators and are sometimes utilized by farmers to pollinate crops, including apples, pears, and other fruits.  Females are capable of stinging, but will rarely do so. 

Control

Mason bees are beneficial native pollinators and control is not recommended. While they may occasionally be spotted near windows and doors looking for small holes to nest in, these areas are not suitable and the bees will leave after a few weeks. Rarely, they may make their way indoors, however, they are docile and can be safely removed and relocated outside.
