I have bats in my chimney. i was told its illegal to kill them

Customer Question

i have bats in my chimney. i was told its illegal to kill them (ie smoke them out, etc) To wait until it gets colder and they will leave on their own. Is this true? They got in because the cap came off of our chimney. I never realized just how noisy bats are. Also, what about their feces, will it make us sick? we have a fireplace insert so they can't get in the house and their droppings are probably going behind the insert. If we can't get to it, is it safe to light a fire when they are gone and allow the high temperature dry the guano out? Any thoughts or suggestions much appreciated. Please dont give me a google answer, i've gone that route already.

You can light a fire before they leave.
They will have time to get out safely.
Maje sure the screen is off the chimney
and do not use paper or anything that
will make sparks. Small tree limbs will work fine..
Keep the limbs burning for about twenty minutes or
so and then go on the roof and replace the chimney screen and cap.
You will want to have all this ready so the bats dont come back
while you are working on it.
Replace the cap and screen.
You have a couple of choices about the guano.
If you are not sensitive and there have been no
Problems or odor you may be ok just leaving it until
it dries.
A second solution is working with a flashlight to pour a generous
amount of baking soda down the chimney
in an attempt to cover and neutralize the guano.
It will not burn or cause any problems.
A third and although expensive solution
Is to have all this professionally done.
Have The insert removed and the area
thoroughly cleaned.
A licensed professional will be familiar with any laws and
Check with your home owners insurance
to see if have coverage for this.
I will be glad to answer any questions you may have. Customer

Some species of bats are protected.
In Illinois there are 12 protected species.
Long eared northern bats are protected.
just about everywhere up north.
There are also birds that live in chimneys.
Your best bet may be to have a professional
pest/ animal remover service to come out and
see what you have and if they are protected.
If bats are protected in your area this may be
something they will do for little or no cost.
In any event homeowners smoke bats and birds out every
year without even realizing it when they light their first fire
They dont waste any time getting out when they smell
smoke so I dont imagine you have harmed any over the
years. Customer
