Any other ‘non-insect’ pests which are found on traps in large quantities (10 or more

only) are recorded in the ‘Others’ column and total counts of all added to the ‘Other

Insects’ column on the monitoring sheet, please do not plot these onto site floor plans.

If many of them are found, try to make an approximate count. You can also record

mouse fur found on traps or signs of mice eating traps in the ‘Others’ column.

Any insect pests or frass which are found on floors or window ledges etc must be listed

in the separate ‘Collected’ column worksheet. Please list against the relevant room or

trap number nearest to where they were found otherwise add them on after trap

numbers and list the location where found - this is very important information we need.

The same applies with any quarantined collections.

Very important – we record moth pheromone lures used as ‘CBCM’ (Case Bearing

Clothes moth) and ‘WCM’ (Webbing Clothes Moth) against the appropriate trap

number ie. ‘CBCM 10’ or ‘WCM 20’. In the ‘Others’ column we record ‘pheromone

lure used’ and, if applicable, if it’s a low-dose one etc.
