Pest handling

What to do before we arrive

Do this

  • Remove webs and egg sacs with a vacuum, including the crevice tool along skirting
  • Reduce clutter in lofts, garages and under-stairs cupboards
  • Fit brush strips to gaps under external doors
  • Deal with the flies and moths they feed on

Avoid this

  • Do not assume every large spider is dangerous — UK species rarely bite
  • Do not spray insecticide widely; targeted treatment of entry points works better
  • Do not leave outside lights on at night; they draw in the insects spiders follow
  • Do not ignore a sudden rise in numbers — it usually signals another pest
