Open downspout ends are a chipmunk hideout
The problem GutterGate was built to solve.
Chipmunks climb up downspouts and tuck themselves inside the open end for shelter.
Once inside, they can nest and work their way toward the house through the pipe.
Fall is peak season — chipmunks look for warm, protected spots as temperatures drop.
Cap the opening — keep chipmunks out
- Mounts on the downspout end at ground level with two screws — about a minute to install, no ladder needed.
- Hinged door swings open for water flow and stays closed otherwise, so chipmunks can't get in.
- Durable ASA is too tough for chipmunks to chew or push through.
- Made in the USA and built to last forever.
What customers are saying
Real reviews from GutterGate customers.
“We had chipmunks hiding in our downspout extensions all the time — even had a black snake come out of one once, and it drove our dog crazy. Since putting GutterGate on, no more issues.”

“I could hear chipmunks climbing up the downspouts and kept worrying they'd find a way into the attic. Installed these caps and haven't heard them since.”

Chipmunk Deterrent — Frequently Asked Questions
How does GutterGate keep chipmunks out of downspouts?
It caps the open end of the downspout at ground level. The hinged door lets water flow out but stays closed otherwise, so chipmunks can't climb up into the pipe.
Is it hard to install?
No. GutterGate mounts on the downspout end at ground level with two screws — about a minute with a screwdriver or drill, no ladder required.
Will it affect water drainage?
No. The hinged door swings open for water flow and stays closed otherwise, so your downspout drains normally while keeping chipmunks out.
