What are Chimney Swift Birds?
Chimney swifts are birds that build their nests inside residential chimney flues, above fireplaces, and on the boiler smoke stacks of industrial-style buildings.
Why are They a Problem?
In large numbers, their nests may reduce the drafting efficiency of a flue while fires are burning. The birds’ raspy “chitter-chatter” that emanate from the fireplace are often annoying and disturbing to homeowners during the 14-18 days that chimney swift chicks are in the nest.

Chimney Swift vs Bat: How to Tell the Difference
Time of Day
To figure out if you’ve got bats or swifts in your chimney, you’ll need to see what time of day the animal is active. Chimney swifts will fly into your chimney at night whereas bats will fly out of it.Do you have winged animals returning to your chimney as the sun sets? Sounds like you've got swifts.
Another sign that you're dealing with chimney swifts will be what you hear. When you've got a bird problem in your home or business, you'll hear chirping, flapping wings, rustling, and scratching.
Dangers of a Chimney Swift Infestation
There are several dangers of having swifts in your chimney:
- They clog up your chimney. If you start a fire without knowing there are birds in your chimney, their presence could plug up the area and smoke will come back into your home.
- Swifts can spread airborne diseases. Bird droppings can spread diseases like histoplasmosis.
- There's a chance they'll bring other pets inside. If you’ve got swifts in your chimney, they may bring other pests like fleas, ticks, and mites into your home.
Along with the dangers above, the presence of chimney swifts can simply be annoying—they can cause quite the racket.
