There are 3 National 'Bug Busting' days every year. They are the 31st January, the 15th June and the 31st October. Studies have shown that if schools encourage families to take part in these days the number of reported infestations does drop! Why not take a look at the Bug Busting website (see link below) in the meantime and give bug busting a go?
