Can Pigeon Droppings Be Used as Fertiliser
There are silver linings around every dark cloud, and just one of the ‘silver linings' that you may have seen for having pest pigeons hanging out on your property is that you can use their droppings for fertiliser. It seems like that would be the natural order of things, right? Nature working its magic? In one sense you're right about nature working its magic, but as with most things in life, there is bad for every good.
Can you use pigeon droppings as fertiliser? Probably, yes.
Should you use pigeon droppings as fertiliser? Nope.
Here's why …
Pigeon droppings are actually corrosive when found in a decent amount, and this means that it will naturally burn or corrode away the materials it comes into contact with. If that's on your roof, it could mean the roof tiles, the fixing material, wood, or even waterproof linings. The droppings could also have an effect on the plastic guttering that surrounds your house, and other pipework that enters and exits the building. If you were to use new or fresh pigeon droppings to fertilise soil, the highly alkaline makeup would simply burn the most delicate segments of the plants you have growing there. This includes not just the stem, but the roots, too. You would need to allow for a period of "cool down", where the pigeon droppings lose some of those alkaline properties.
If you choose to use pigeon droppings in your compost waste, you will need to only add small amounts of it at once, otherwise it will 'contaminate' the rest of the material within that heap. It'll slowly turn the rest of the material alkaline, and then the whole lot will give you plants a very unhealthy and hostile soil to grow in. If you *are* going to add pigeon poop to your compost heap, make sure you're only adding around one part of the waste to five or six parts of everything else.
And now we come to the most dangerous part of using pigeon droppings as fertiliser for your flower garden or vegetable patch ...
Urine and feces of animals will contain parasites and disease spores. That's the case for ALL wild animals, and even some of the animals that we've domesticated over the years. Pigeon droppings contain an abundance of potential disease-causing spores, including the bacteria responsible for E.coli and salmonella poisoning. This, alongside many other viruses and bacteria, are then liberally sprinkled all around your plants when you use pigeon droppings as fertiliser. Other animals can pick up the bug — your pets, for example — and they'll then bring that bug into your home where it can be contracted by your children, household visitors, other family members, and perhaps even further widespread than that.
You CAN use pigeon droppings as fertiliser, but it's a long process that requires a lot of work to ensure you don't get it wrong. It is only recommended that you use droppings from domesticated pigeons, not feral/pest pigeons to reduce the disease threats, but you are still privy to a range of potentially dangerous diseases even in those cases.
