The oak processionary moth can be a scourge of parks with lots of oak trees. And Perivale park has quite a few mature specimens. Almost three years ago we highlighted what can happen when a tree becomes infested. So it was good to see that the parks department continues to regularly spray the trees to avoid any resurgence.
According to the chap blasting our trees as seen in the photo above, it is well under control now. It is a shame one cannot apply an equally efficacious spray to prevent littering in the park!
