Pest update

Because of the coronavirus situation, and the closure of the University of Warwick premises, the 3 yellow water traps have been moved to the allotments in the village of Tysoe, 10 miles from Wellesbourne. The aim is to empty the traps daily - on my exercise route.

The traps were set up yesterday and captured 4 pollen beetles.
