Downspout Pest Deterrent — Keep Critters From Climbing Into Your Home

Open downspouts are a highway for pests. GutterGate seals the opening so mice, squirrels, snakes and insects can't climb up and into your attic or walls.

Pests use your downspouts as a doorway

The problem GutterGate was built to solve.

Mice and rats climb up downspouts and squeeze into gaps around your foundation.

Squirrels and chipmunks nest in open pipes and chew into your soffits.

Snakes follow the same path indoors, especially near wooded lots.

The Solution

A physical barrier pests can't get past

  • Caps the downspout opening with durable ASA — too strong for pests to chew or push through.
  • Seals the gap so insects, rodents and reptiles can't enter from the bottom.
  • Installs in seconds with a screwdriver or drill; stays put through storms and seasons.
  • Doesn't trap water — full drainage flow is preserved.

Downspout Pest Deterrent — Frequently Asked Questions

How does a downspout pest deterrent work?

It caps the open end of your downspout with a durable barrier. Pests enter downspouts from the bottom outlet and climb up into your home; sealing that opening stops them at the source without affecting water flow.

Will it keep snakes and mice out?

Yes. GutterGate forms a solid, chew-proof seal across the downspout opening that mice, rats, squirrels and snakes cannot pass through.

Does it work with underground drainage pipes?

Yes. Our 4" Round Corrugated Pipe Adapter connects GutterGate to standard 4" corrugated underground pipes so the pest barrier stays in place.
