Chimney Balloons to squirrel, raccoon, opossums and larger vermin.

Q: Jason, A couple of times in the last few years we’ve had flying squirrels come down the chimney.

How resistant are the Chimney Balloons to the claws of little critters such as this? (I would put a screen on top of the chimney but I’d have to rent a lift to do so. Tall house, taller chimney, steep roof…) Thanks, – ADH

A: Dear ADH, Have you got a friend with a bucket truck or cherry picker? No?, neither do I, but I wish I did many times.

Chimney Balloons hold up well keeping out birds, bats, insects, and wasps, but they fall short when it comes to raccoons, squirrels, mice, and opossums.

If the critter has teeth and claws, you are going to need a wire mesh cap on the chimney and I would spend the extra to get a stainless one so you don’t have to replace it soon. Don’t risk your neck on your steep roof, call a chimney sweep to put the cap on for you. And if it is opossums or raccoons you are trying to keep out of your chimney make sure you anchor it VERY well. Those critters have the strength of a Gorilla when it comes to removing chimney caps! – Jason

Q: Jason, I have an awful fly problem, and I think they are coming down the chimney looking to get away from the outside heat.  Will the Chimney Balloon stop flies for sure? – MH

A: Hi MH, From our conversation on the phone,  I was glad to hear you had your fireplace cleaned recently. Sometime fireplace flies have to do with a dead animal in the flue, or pigeons using your chimney top as an outhouse. But since you have a screened chimney top and a clean flue we can rule that out.

Flies and wasps coming down through the fireplace is a very common issue, and the Chimney Balloon does stop them. Especially in spring and fall insects follow food and other smells down into the fireplace chimney and end up inside. We get this questions so frequently there is  a section of our website dedicated to it: http://www.chimneyballoon.us/bat_wasps_in_fireplace.html and some other blog articles regarding wasps as well: http://www.chimneyballoonusa.com/blog/2009/11/help-wasps-are-coming-in-through-my-fireplace-damper.html

The key to stopping flies in particular is to get an accurate measurement. Here is a section of the website that outlines how to do that measurement: http://www.chimneyballoon.us/Chimneyballoonsizing.html also you can give me a call or email pictures if you want advice on the measuring.

Once you have the measurements we need to get a Chimney Balloon for you that is as close to your measurements as possible (even if we have to go with a custom size), so you get a perfectly tight seal. Flies and maggots can be persistent in their entry techniques so you don’t want wrinkles in the Chimney Balloon from the too much extra material. – Jason
