Bats in the attic
 
Well, we have bats in our attic. Not too sure how many. We have seen 2 adults, about 8 months apart. And we know there are bats (unknown amount) living there currently, as we have seen droppings accumulate. I have an old Victorian home with (I can only imagine) multiple ways of ingress/egress for them.

They have not come into my living space...yet and we only use the attic for storage so we've developed the attitude "live and let live". I know we need to exclude them, though. Does any one have a suggestion as to how? What products and techniques are best? Do bat houses placed outside help by giving them an alternative habitat? If so, how do you build one and where is the optimal location to place it?

I will say, we have an affection for animals and the ecosystem. I'd love to not harm them and provide them with an alternative home. Plus, they help keep bug populations down. Any advice would help!

Thanks!

I would spend the time to find out how there getting in.
No screen or broken screen on a gable vent. loose or rotted siding or fasha board?

they have probably been living in your home for some time now,probably multiple generations,getting them to leave on their own is not going to be easy

just for a start go up in your attic during the day,turn off any lights and look around,if you can see day light your looking at a potential entry point


professional pest control may be your best bet,make sure they don't kill them,just get them out and seal up the entry points

this may take awhile:(

Thanks for the link! There are some obvious entry points, including a small opening in a roof vent screen where they could enter but the last thing I want to do, as I have been reading, is close that up and prevent them from getting out and thus making their way into my living chambers in search of food escape. Anyway, thanks for the advice and keep it coming!

All it takes is one loose piece of old siding for them to get in.
Just look at the sample plans I posted. Some have siding with spacers under the bottom to let them on.

Tom,

Have you had any experience with a pro? What is their usual method for getting the job done? Traps? Excluders?

Etrace0921 02-28-2012 11:15 PM

Also, what are your opinions on traps, or ultrasonic repellers?

Tom Struble 02-29-2012 09:32 AM

the best time to start is at dusk,you can find out their main entrance by waiting and seeing where they come out,then is the time to close off the entry point,but the problem is there may be more than one

pro's will go in with nets,i don't recommend you do that,they also have anti roost chemicals that will discourage them

PAbugman 02-29-2012 06:16 PM

The ultrasonic repellers donít work at anything. The bat house will not relocate the bats. As long as your attic is appealing and accessible thatís where they will go. To not injure them you will need to wait for warmer weather before excluding them. What the bat pros do is to use a ďman-liftĒ, or cherry picker to get them up high. Install flaps or somesuch to act as a one-way flap or valve so they canít get back in. Then sealing, repairing takes place. This is expensive work. If you canít get them out on your own you may need to hire a bat pro. The colony will just get larger to the point of danger. On the other hand, you might get on the show ďInfestedĒ! My apologies for the untimely humor.

Tomís advice about looking for daylight in the attic is good. Iíve done this many times to show the homeowner what they had up there. I donít do bats, but Iíve been in plenty ofhouses that had bat issues. Iím not familiar with the anti-roost chemicals; would be good to learn of them. This will most likely be a multi-faceted approach. Keep us posted.

Call the Morton Arboretum in Lisle Illinois---ask for a naturalist---There is a 'bat rescue' group in this area that humainly removes bats --all volunteers--

The folks at the Morton Arboretum should have the name of that outfit---There might be another group like that in your area---The bat rescue people may have a name for you if there is one---

Etrace0921 02-29-2012 11:07 PM

Thanks so much!!! The weather is turning, and we are going to be painting our home this spring: a good opportunity to investigate modes of egress and ingress. I will probably consult this group from Lisle...I may even seek bids from bat excluders. If I can afford it, I will probably use them. If I can't...then wish me luck! Thanks again. I will keep you all updated!

I'm pretty much for "live and let live," but NOT for bats in my house - there's a huge rabies problem where I live. We had eight or ten of them in the attic of our log home while we were still building it. They got trapped when I put in the soffits, and came into the living space. A .410 shotgun and birdshot took care of the problem in a hurry.

:laughing::laughing: You have style---and rabid bats are a serious problem in some areas.

Thanks. I first tried .22 shot shell in one of my pistols, but it mostly bounced off the logs. Wouldn't recommend my solution in a house with drywall.
