and are the favourite haunt of these insects, but they take shelter in any of sufficient size, as well as hiding in brassicas. The best and simplest trap is still the small flowerpot, stuffed with a little dry moss or hay and inverted on the top of a stake.

Another simple device is a roll of corrugated straw-board, one end thrust into a matchbox cover. BHC or Pyrethrin insecticides will control earwigs.
