They’re only pigeons roosting in the building, what can possibly go wrong?

Urban birds are on the increase with aided by the abundance of food, roosting options, and the dwindling natural predators. This population explosion has caused some birds to become pests by their sheer numbers. Look at Geese for example or Haddidas, not your typical pest species, but due to their numbers, they can be considered a pest by some.

As these pest species increase in numbers, they inevitably must spread out to find suitable roosting areas for the next generation. Feral pigeons can live up to 4 years and in their lifespan can lay up to 32 eggs. These eggs will hatch in 18 days, the young will be out of the nest in 35 days and looking for a mate as early as 7 months. The cycle perpetuates and the species rapidly increases.

The average Feral pigeon is not too fussy when it comes to picking a roosting spot. All it needs is food, water and somewhere relatively safe to sit. This makes office buildings and industrial areas ideal for a young feral pigeon couple looking to settle down and start a family. As these birds do not migrate and prefer to stay near their birthplace, they can be troublesome to remove. Once you have a pigeon problem, things are not going to get better by themselves, you will need to look at your pest control options.

What sort of damage can you expect from feral pigeons?

Outside the building

Pigeons will foul the areas below their roosting areas. Their tactic is to back-up over the edge and release a stream of droppings on anyone and anything that is unlucky enough to get caught below.

For business premises, this causes and unpleasant scene for visitors and can damage cars parked below and create an injury and health hazard.

For industrial areas and warehousing, the pigeon droppings can damage goods, raw materials, food packaging, etc. resulting in financial loss.

Birds roosting outside in the gutters will disrupt the buildings’ drainage causing water to build up, allowing insects to breed and increasing the risk of water damage to timbers, metal fittings, and wall cladding.

People outside the building may experience aggressive bird behaviour when they come too close to any nests containing chicks or while eating their food. Gulls and starlings are particularly aggressive when it comes to stealing food from people.

Meanwhile…Inside the building

While pigeons are not too fussy where they roost, they will prefer to be somewhere warmer than hugging the ledge or external piping. They will gain access to the building if they can and that is where your trouble really begins.

Property damage

Feral pigeons have the time and tenacity to wear down the defenses of your building. They will dislodge roof tiles, make holes in roof spaces and exploit any weaknesses in the building's structure.

Once inside their droppings will build-up, along with the additional pests (mites), bacteria and diseases that accompany the feral birds.

Birds are not tidy house guests and will quickly make a mess of the insulation in the roof spaces along with any air conditioning installations, lift motor machinery and anything else stored there that they can sit on, poop on or peck.

For food manufacturing and food warehousing, the pest birds will inevitably gain access to the storage areas and spoil the food and packaging.

Risk of Disease

Feral pigeons are host to multiple types of bacteria, diseases, pathogens, and viruses (E. coli, Salmonella, Histoplasma). Their general living habitat is a petri dish for all manner of nasties that can get into the building air supply, contaminate the water supply and food, causing sickness and disease.

Pests attract pests

A pest bird infestation attracts other pests – fleas, ticks, mites, lice. This, in turn, creates its own new ecosystem where larger insects come to eat the bugs. The insects and birds attract the rodents and reptiles and soon your ‘unused roof area’ is teaming with life.

If you would like your building to be more like a place of business and a lot less like a bio-hazard wasteland, then get in touch and we will be happy send the pest birds packing!
