One bottle,
every place they get in.
Donaldson Farms is a small family business that has been making plant-based pest solutions since 2016. The Bat Repellent Spray is the one customers come back for, and it is the product our bat pages are built around.
Bat Repellent Spray, 16oz
The plant-based peppermint spray that drives bats away from nesting areas without harming them. Non-aerosol, indoor and outdoor.
Bat House Attractant, 2oz
The other half of moving a colony on humanely: repel them off the house, then give them somewhere else to go.
What is in it,
and what is not.
Peppermint oil and plant-based ingredients in a non-aerosol trigger bottle. Nothing that kills, nothing harsh.
What the first week
usually looks like.
Written from what customers describe in their reviews. Every roost is different, so treat this as the shape of it rather than a schedule.
You spray the entry points
Shake, then spray the eaves, vents, soffits, beams and cracks they use. Evening works best because that is when bats are most active.
The roost stops smelling right
Many customers report bats gone within the first few nights of spraying. One reviewer counted 24 leaving the same evening.
You go round again
Reapply weekly, and after heavy rain outdoors. This is the step people skip and then wonder why one comes back.
You keep the entry points treated
A 16 oz bottle gives you plenty for the entry points and regular reapplication.
Next to a typical
chemical deterrent.
The difference is the approach: this one changes how the roost smells instead of treating it.
Donaldson Bat Repellent Spray
Compared with chemical bat deterrents commonly sold for home use. Always follow the rules in your area on when bats can be moved on.
The people who
reach for this.
Four situations show up again and again in the reviews and in the questions we get.
Heard it in the attic
Scratching overhead at dusk, then guano on the insulation. You want them out before it spreads, and out without a mess.
Guano on the walkway
They roost under the porch or the eave and the stain shows up on the front walk every morning.
Barn and outbuildings
Open structures are easy to roost in. You need something you can spray over a wide area and repeat.
Wants it done humanely
You do not want anything killed. You want the colony to decide to leave on its own.

Kim Barker · 06/06/2026This product really works. We sprayed the area early evening around where we knew the bats were hanging. They flew out and we counted 24.
Amazon Customer · 05/26/2026We had a bat that liked to hang out under our porch at night and was leaving a stain of guano on our front walk. We used this and by the next night it was gone. It has a very pleasant peppermint smell too.

How long before the bats leave?
Many customers report bats gone within the first few nights of spraying. Apply in the evening, when bats are most active, and reapply weekly until they stop coming back.
Will it hurt the bats?
No. This is a repellent, not a pesticide. The plant-based peppermint formula drives bats away from nesting areas without harming them, so the colony moves on by itself.
Is it safe around pets and kids?
It is safe for pets and family when used as directed, with no harsh chemicals. It is made with peppermint oil and plant-based ingredients, and it is cruelty-free.
Where exactly do I spray it?
Around the affected areas and known entry points: eaves, vents, soffits, beams and cracks. It works indoors and outdoors, so attics, homes, barns, garages, decks and porches are all fair game.
What does it smell like?
Light, clean peppermint. Pleasant to you, unpleasant to bats. Instead of a harsh chemical odor you get a fresh mint scent that customers consistently say they love.
How far does one bottle go?
The 16 oz bottle gives you plenty for the entry points and for regular reapplication. How long it lasts depends on how much area you are treating and how often you go round.
How fast does it ship?
Orders are processed within 24 to 48 hours and ship free anywhere in the US via USPS flat rate or priority. They typically arrive within 3 to 8 days depending on location and time of year.
What if it does not work for me?
Return it within 30 days of purchase for a full refund. Return shipping is paid by the buyer, and the refund is issued 1 to 3 days after we receive it.
