Rats and Mice

Rat Silhouette

Both rats and mice cause damage to buildings and materials. e.g. Food, stock, packaging materials, pipework, electrical wiring, insulation, and anything else that is available to chew. Damage to wiring is frequently the cause of fires. They may enter properties through gaps above or below ground level. Because of their climbing and agile ability entry may be at any level.

All rodents transmit disease to man and livestock. The diseases are transmitted in their urine and are also carried on their bodies.

Weil's disease is of most concern, which if left unchecked, can kill.

Other serious diseases are Salmonellosis, Rat bite fever, and Typhus.

Rodents will also carry and transmit ringworm, mites, nematodes, tapeworm, ticks and fleas.

Rats and mice will contaminate surfaces, stock, materials, and foods with their faeces, urine,and hairs.

Rats and mice can re- produce from the age of 3 months old, producing litters every 24 to 28 days.

The size of each litter may vary from between 6 and 11 offspring. As a consequence this can give rise to rapidly increasing numbers.

The tell tale signs of rodent activity:

  1. Sightings. If sightings are seen during the day, it suggests a large infestation may be present.
  2. Smell - Stale odours produced by rats and mice in long standing infestations.
  3. Droppings - Rat droppings are on average 12mm long, Mice droppings are 3-7 mm long.
  4. Runs. Pathways of regularly trampled vegetation, worn trampled earth. Footprints on muddy or dusty surfaces.
  5. Smears on pipes, cables, walls, entrance holes.
  6. Burrows in the ground.
  7. Damage to goods and structures.
  8. Partially eaten, spilled or hoarded food. Damaged materials, and signs of recent gnawing.
  9. Noise ( Scratching and the sound of scurrying
  10. Noises in the loft, below floorboards, above ceilings, and in the cavity walling.

To obtain full control of rodent infestations, full and thorough surveys must be carried out to identify and if possible remedy the cause of the problem,as well as dealing with potential access points, harbourage, food sources etc. Inadequate surveys will ultimately cause treatments to fail.

Risk assessments are carried out in all circumstances to safeguard children,and animals.
