Cars and paved areas around Rugby are likely to be stickier than usual over the coming weeks.
Forestry experts in Warwickshire are warning that there will be a sudden emergence of sap-feeding insects following the unusually cold spring. This in turn will cause more droplets of sap to form and fall to the ground.
The drops, commonly known as ‘honeydew’, cover anything beneath the tree.
County forestry officer Ken Simons said: “The honeydew is sticky due to presence of sugars and readily turns black as moulds feed off these sugars. Washing with a mild detergent will usually remove the honeydew from cars and paved areas.”
Mr Simons added that most species of tree are in good health, despite the cold.
