Bee's Pensby, Wirral
Mason bee's do not form colonies like honey bee's or bumblebee's. They are solitary insects that nest in reeds, holes in wood or holes in stonework and mortar. They are not generally considered pests unless they become of concern to the property owner.
I attended a call in Pensby, Wirral, and was confronted by a large number of bee's visiting an empty flower bed in the middle of a lawn. The flower bed was circular and about 3 metres in diameter. The soil was relatively heavy clay and had been recently flooded (within 2 weeks).
The bee's had dug a circular hole in the soil which was about 5 inches in diameter and about 2 inches deep. At the bottom of this pit was a hole the size of a 5p with multiple tunnels leading off from the entrance. The bee's where carrying clay from the flower bed to holes in the brickwork in the house (to nest) but where also using the putty like clay of the flower bed to make nest holes in (the hole/tunnels at the bottom of the pit).
To stop the bee's using the flower bed involved using methods to remove there preference for the border.
The small nesting site was treated with insecticide then the border was turned over using a spade and then compost picked up from a local garden centre was added to cover the clay.
The bee's were also found to be nesting around the doorway of the house. They were using holes in the brickwork. The insects lay their eggs at the bottom of the hole and then fill the hole with pollen for the larva to feed on. The hole is then plugged with clay and left by the adult bee. The photo shows the bee plugging the hole with clay.
Bee's are a very important part of the pollination process for flowers and crops but when they become a concern for the property owner they need controlling.
The compost on the border will stop the bee's from using that source of clay, and a small amount of insecticide into the bee holes around the door will stop any further activity by the house. The holes will be plugged to stop any further bee's nesting.
