Help! I have a bat problem


Anyone have suggestions or techniques to keep colonies of bats from nesting and retuning nightly to crevices and corners of my outdoor patio.

They leave a mess with their dropping's and flung their urine onto windows and walls of my home. I have to cover all of my outdoor furniture. Its a job to keep cleaning windows, but you can see from the photos how badly these bats mess up the windows. Help!

    Hi Suzanne! Yikes.....haven't seen this problem before. I googled remedies for building a "Bat House" in your yard..... and there were a lot of suggestions and videos. Here's one below. Hopefully, you can find a remedy for cleaning in the articles where they are roosting on your patio. Can you possibly screen in your patio to keep them from returning? Best of luck!

      Stucco arches are not designed to be screened easily. We have dozens of bat boxes posted around the ranch but they ignore them and come to the house instead.
      Bats are great hunters of mosquitos and can eat about 6,000-8,000 per day. We live near a river and its many tributaries that has been designated as a West Nile positive area, so the bats are welcome , but not under the eaves or porches of my home.

    I've been told that bats dislike light. My suggestion would be to string up some high wattage lights overnight for a week or two. Hopefully, they will move out of your area.

    Oh that's all kinds of nasty!!! However, bats are protected in a lot of areas and "harassing" them can result in fines . Contact your county extension office or vector control for their recommendations.

    try usin sticky boards along with moth balls. I had to call an exterminator and he used the sticky board. Another suggested I use moth balls. Fortunately, they found where the bats were entering my attic. They used a device that sealed the hole and any remaining bats could leave but never return. The job was costly, but worth it. Good luck padoyle
