Pigeon guano in a loft: risks and safe removal

Bird fouling in a loft, on a flat roof or in a disused building is more than an unpleasant mess. Dried droppings become airborne dust as soon as they are disturbed.

Why you should not sweep it out

Dry guano breaks up easily. Sweeping or brushing sends fine particles into the air in an enclosed, poorly ventilated space, which is the worst possible way to deal with it.

Bird fouling can carry organisms associated with respiratory illness, and nesting material commonly harbours mites and insects that migrate into the rooms below.

What a proper decontamination involves

The aim is to remove the material without making it airborne, then treat the surfaces underneath.

  • Respiratory protection and disposable coveralls throughout
  • Fouling dampened down before removal so it is not disturbed dry
  • Contaminated insulation removed and bagged rather than cleaned
  • Nesting material and carcasses removed and disposed of correctly
  • Surfaces cleaned and biocide treated, then the space left ventilated and dry

Stopping it happening again

Cleaning without closing the entry point simply resets the clock. Missing tiles, open soffits, damaged vents and broken roof lights are the usual routes in.

We are cleaning and decontamination specialists rather than pest controllers or roofers, so we will tell you plainly what needs proofing and leave that to the right trade.
