Donaldson Farms Bat Attractant Spray for Bat House – Nature-Derived Lure and Scent to Attract Bats to Boxes, Wood, and Outdoor Structures or Garden Habitat for Natural Outdoor Use - Made in USA - 2 oz

I bought this in January and applied to my bat house on Jan. 20, 2019. I followed the instructions explicitly. 5 sprays on the bottom (entry) of the house. I check almost every day if bats are in the house. I waited a month as instructed and sprayed again at the end of February - 5 sprays on the bottom of the house. Kept checking daily - no bats.The third application was done at the beginning of April. But this time I decided to do a few more sprays. 8-9 full sprays instead of 5. Kept checking daily. Today April 9, 2019 - two bats in bat house - an adult and a small pup.Update June 13, 2019: In May I had an explosion of bats - big brown bats to be precise. During the first week of June I counted 45 bats (as they left the bathouse in the evening). I read that these species of bats will congregate right before giving birth. There were a number of pups in the bathouse. After a big storm this past week, the bats all left the house. Today, 3 days after that storm I see 2 bats in the bathouse.

We had a bat house on our farm with bats in it. One day we noticed that all the bats were gone. My husband climbed up to investigate and saw that the house had been taken over by hornets. So he cleaned them out. A few months passed, but there were still no bats in the house. I bought this spray and he applied it as directed. A month later we went to reapply the spray but realized that a bat had already moved into the house. Two months after that single application and we now have nine living in there. Since it worked so great the one time we used it, we still have plenty of spray left in the bottle. We plan on building additional batboxes for other areas of our property and using up the rest of the spray there.

I didn’t even get to the point of opening the shipping bag it came in. I could smell it already. Half of the bottle had leaked out all over the inside. Smells horrible and it made my kitchen smell awful. Don’t know if I’m a fluke but open outside with gloves to be safe because the smell has yet to come off my hands.

I understand it's not a miracle worker. My problem is we hung the bat house so high, it's difficult to re-apply.All I can say it it hasn't worked with only one application. Directions don't say how often you should spray again.

Used this for two years on my bat houses before they moved in so not sure if the spray helped.

Recommend this be bought with the bat house as it has ingredients to attract bats to colonize the bat house instead of your hime.

Hard to know if there are other reasons but certainly seems ineffective

The attractant was shipped immediately. I have applied it to my bat house. However, I stained my bathouse last Fall and it might be a couple of years before it is occupied. Bats have sensitive smell and stain is not appealing at all. I stained the pine because in my area I didn't think it would hold up to the weather very well. All told, if I don't get bats, I don't feel it is the attractants fault. If I do get bats, this stuff is Very good attractant!
