Hi Nikita, uou are quite right, they aren't a new threat. They've been in the south for decades, but they are spreading much further north and are invading sensitive/rare habitats. wiping out fragile species. The problem seems to be the ease and speed with which they spread along watercoursesm hence the concern of environmental conservation bodies.
I am still picking these damn things out of the dogs' feathers, and Jack being a total crybaby is making life doubly hard by squealing for all he's worth, which has put the other two off completely--they will stand or lie down for a couple of minutes at most while I pick at their coats, and they have a show on Sunday. Until they are free of these things I daren't let them off lead either.
