Tips and Products Household Owners Swear-By To Bird Proofing A Chimney

Every year, households face the dilemma of driving birds away from their chimneys. Birds roosting and nesting on the chimneys are both harmful for the flyers itself and the occupants of the house. Birds like house sparrows, pigeons, and more flyers can get stuck into it and die. And when these birds build a thick nest on the chimney, the smoke from the flue will be diverted back to the house which spells trouble. Knowing how to bird proof my chimney is one way to prevent this from happening.

The winter season is probably the safest time against these perching birds. The continuous heat from your furnace will drive them away but once the summer and spring start to take over, you have to do something. Birds find chimneys to be more secure against predators but it will cause problems if you don’t stop them from flocking.

Dangers of birds on the chimney

These birds seem to be harmless. But once their droppings and nests start to cause a massive problem, it’s only then that you’ll realize the threat. Never underestimate what danger these flyers can bring to your household. Here are some risks of the nesting birds that might probably send you checking your chimney.

Histoplasmosis

Histoplasmosis is a lung disease caused by inhaling fungal spores found in soil and bird droppings. Since spores are airborne, even those who didn’t have direct contact with the dropping can contract the illness. This case isn’t alarming for those with a healthy body as some people don’t even exhibit symptoms. But for those who have weak immune systems, the infection can spread to different parts of the body and cause more health complications. This is the reason why I looked for ways on how to bird proof my chimney.

Some common symptoms of histoplasmosis are fever, dry cough, joint and chest pain, and red blisters. The blistering happens in about 15% of the cases which is just a small chunk of the overall percentage.

The only consolation about histoplasmosis is it doesn’t spread from human to human. But if there are other occupants in the household, he or she may directly inhale the spores and get infected.

More bacterial, fungal, and viral infections

Aside from histoplasmosis, there are other infections that may happen to those exposed to the droppings. The likes of “Parrot Fever”, food poisoning, and cryptococcosis may take place. Most of these aren’t lethal but those with immune system issues will suffer more. The dangerous part here is that some of the infections can mimic typical illnesses like typhoid fever or the usual flu.

Secondary pests

One fact that made me search how to bird proof my chimney is that birds aren’t just carriers of diseases. They also carry other pests like ticks and mites that may soon pester your home. Since you’re not using your fireplace that much during spring and summer, these small pests will soon take over your household without warning.

Fire hazard

When birds nest on your chimney, they will bring shreds of dry straw and leaves. This seems to be harmless until you light your fireplace for the first time after some months. Those dry stuff can ignite easily and start a fire. The offspring on the nest will die and your house might experience minor to severe fire damages.

Products That I Use On How To Bird Proof My Chimney
