6. Experience shows that the most efficient means of trapping 

 the beetles is to lay here and there on the ground in newly-cleared 

 and infested areas pieces of fresh Scotch pine bark, 8 to 12 in. long 

 by 4 to 6 in. wide. These should be laid on the surface (not 

 below it), with their outermost surface upwards. The beetles

collect on the under surface for feeding. These traps must be 

 regularly visited, and the beetles destroyed, either by dropping 

 them into boiling water or into a vessel containing paraffin. 

 The traps must also be often renewed, as when they dry and 

 lose their odour they cease to attract. In Scotland, thousands 

 of beetles have been caught by these means. It is of the utmost 

 importance to proceed against Hylobius in its breeding places, 

 and not wait till the beetles have started to feed on the young 

 plants.
