Home & Lawn Pest Control : How to Rid Your Home of Bats


Hi I’m Jim Harmon, California Pest Management.
We’re going to talk a little bit today about bat control in your house. Now remember bats
are good for the environment. They feed on the bad insects, on the mosquitoes, they’re
eating those all the time. But unfortunately their guano or feces is very dangerous, we’d
like to keep them in the caves and the tree areas so that way they’re out in nature doing
what they’re supposed to do because they’re basically they are nature’s pest control.
But unfortunately sometimes they get into our houses. This house for example has got
a nice opening on the end. This is for ventilation, but we’ve got squares and one of them has
popped open it had all screen on it and now bats have gotten inside. How we’re going to
control this, make sure everything is screened up except for the one opening they’re using.
Now we put a funnel trap. Now the funnel trap is simply a funnel made of hardware cloth
and at one end of it is a trapdoor. Door opens out and it’s over sized so it opens out and
it doesn’t open back in. You can make this very easily with hardware cloth, make it into
a cone, open at each end, at the small end of it should not be bigger than the size of
a quarter, about that, then take a small circular section of hardware cloth that’s cut a little
bit larger than that small opening, wire that in so it’s a hinge, put that up on the wall,
now you have your one way exit. They can only come out, they can’t go back in. Make sure
though they don’t have any babies because then you’re going to have all kinds of dead
babies up here and that’s not a good thing. Cleaning up from bats, that can be a little
bit of a chore, make sure you either have professionals do it or suit up with appropriate
safety protection. Good luck.

  1. Use bat houses in the trees & attract them there so that you still get the benefit of their insect control.

  2. hi Jim,
    i have a question.I hope you can help me. Our house is built using concrete bricks with cement in between, we dont have a attic, and our roof is flat open. we have one storey house. all the entrance to our house is not accessible easily.
    I don't live where bats are normal in the area. but for some reason we had bats circling our garden on daily basis for past year or so (around 3-4) once the sun goes down, and we can see them swinging from one side to another. (as our houses have four side boundary walls here in our country).

    they aren't in our house or outside the house. We do have huge trees (non -fruits one) and our neighbour house on the back have been demolished over a year now, on one side we have neighbours living and on the other side we have old open house with no doors but old and being empty over 20 years but a guard living there. (but never saw bats before then few years only)
    recently, past week or two, we had strange black spot dropping on the daily base but never knew what it was. and strangely, it was dropping over of one side of the house
    So we thought it might be bats but how could few bats do so much and its like spraying gun is being used.
    today, as usual after 7pm few bats flew right and left on our back garden. and when we turn in for the day, and after an hour or so, i needed to buy something from the market, so as i was leaving from my door, i notice those same dropping but was still wet and when i looked up they were about 20-30 bats flowing left and right in the same garden only but never at the other side or the front side of the house which have another garden as well.
    the reason for asking is where should i look for them and how to get rid of them, as it is becoming dangerous as i don't want my kids to be out after 7pm
