Pest-Proof Downspout

A Pest-Proof Downspout Cap That Actually Works

Sealing the opening is the single most effective way to pest-proof a downspout. GutterGate's chew-proof cap stops rodents, reptiles and insects at the source.

Open downspouts are not pest-proof

The problem GutterGate was built to solve.

Open outlets let rodents and insects travel straight from the yard into your home.

Squirrels chew through flimsy screens and plastic caps.

Gaps around the pipe give snakes an easy path indoors.

Pest-Proof Downspout — Frequently Asked Questions

How do I make my downspout pest-proof?

Seal the bottom opening with a chew-proof cap. Pests enter downspouts from the outlet and climb up; closing that opening with a GutterGate makes the downspout pest-proof without affecting drainage.

Is it really chew-proof?

Yes. GutterGate is made from durable ASA that mice, rats and squirrels cannot chew through.

Does it fit round downspouts too?

Yes. Our 4" Round cap fits round downspouts, and the corrugated pipe adapter connects it to underground 4" corrugated lines.
