Monitoring System
The Use of Monitoring Traps/Detectors

The main benefit to be gained from the use of monitoring devices is that of time. Physical inspection by nature, are time consuming and rely on the skill of our Entomologist or Specialists.

Monitors such as :

  • Electric Fly Killer (EFK) units
  • Pheromone traps Adhesive detectors are able to collect information from a range of locations over a greater time scale.
Range of Monitoring Devices

Monitoring devices can be grouped into four main categories:

  • Those using ultraviolet light to attract flying insects to be trapped on an adhesive film
  • Those attracting insects by means of a sex pheromone
  • Those attracting insects using a food attractant
  • Pitfall traps

Adhesive detectors may be used un-baited in order to pick up insects, which are moving in the vicinity. These are sometimes referred to as “blunder traps”.

Non Chemical Control Methods
  • Rodent Traps
    • Spring Traps
    • Life Traps
  • Bird Traps
  • Insect Trapping
    • Electric Fly Killer EFK
    • Adhesive Pads
    • Pheromone Traps
    • Pitfall Traps
    • Fly & Wasp Traps
  • Other Physical
  • Control Methods
    • Entoleter (for Milling Industry)
    • Heat Treatment (>55deg C)
    • Freezing ( -35deg C)

Spring Traps

Only spring traps approved under the Pests Act 1954 may be used for killing and taking animals.

Break-back traps commonly used for the destruction of rats, mice and other small ground vermin and spring traps of the kind commonly used for catching moles in their runs are exempted from the requirement to be approved.

Live Traps
Live catch mouse traps are available in either single or multi catch versions. They can be used as an alternative to toxic baits in high risk/ production areas, although the presence of a bait attractant may pose a contamination risk.

Cage traps which catch the target animal live are of limited use as a control measure but may be employed when there is a risk to protected species from other methods. Any animal caught should be despatched humanely. Non-target species must be released unharmed.

Bird Traps
Cage traps are usually constructed from wire mesh, into which birds are enticed using a decoy, or suitable bait. Once inside, the bird is prevented from leaving by a cone entrance, bob wires or non-return door.

It is a legal requirement that birds are caught alive; non-pest species can then be released and the remaining birds can be humanely dispatched. Traps must be visited often to release or dispatch birds. Food and water must be available in the trap to prevent undue stress.

Other (non-lethal) bird control methods

Traditional anti-perching systems consist of sprung wire or spike systems and are designed to prevent birds from alighting on ledges or similar surfaces. Electric wire systems are also available.

UV stable polyethylene or polypropylene netting with an appropriate mesh size for the species concerned:

  • 19mm for house sparrows
  • 28mm for starlings
  • 50mm for pigeons
  • 75mm for gulls
Insect Trapping
The use of insect traps can rarely be relied on as a method of control but can provide evidence of the presence of insect pests and may in some cases reduce numbers.
Insect Traps

The main types of insect traps are:

Electric Fly Control Units (EFK)
Flying insects are attracted to the ultra-violet light emitted by the unit and are either trapped on an adhesive board or killed by means of a high voltage electric charge. As UV emission from the unit degrades rapidly lamps should be replaced at between 6-12 months, preferably in spring.

EFK units should not be placed:

  • Outside or by open windows and doors where they will catch non-target species and may attract pests to the site
  • Beside windows or fluorescent lighting where they will compete with natural sources of UV light
  • Over food preparation surfaces where there will be a risk of fall-out from the unit
Adhesive Pads
The term “detector” better describes the function of adhesive traps. Insects are encouraged to enter the trap by either a food source attractant or pheromone lure and are held on the adhesive surface.
Pheromone Traps
As with adhesive traps the male insect is attracted by the pheromone released by the lure. Once in the trap the insect may be trapped with an adhesive insert or simply be unable to find its way out. The pheromone is specific to one or a number of related species and acts as an indicator rather than a control method.
Pitfall Traps
Generally used in bulk grain, the pitfall trap relies on foraging insects to drop into the trap whose smooth sides make escape impossible. This technique cannot be considered a control method.
Fly and Wasp Traps
Included in this group are various fly and wasp traps, which attract the insects by means of liquid bait. Having entered the trap the insects are then unable to escape and drown.
