Downspout Critter Blocker — Stop Animals From Moving In

Squirrels, mice, snakes and bugs travel up open downspouts straight into your home. GutterGate blocks them at the source — chew-proof and built to last.

Critters love an open downspout

The problem GutterGate was built to solve.

Squirrels and chipmunks climb up and chew into your roofline.

Insects and spiders use the pipe as a sheltered highway indoors.

Snakes follow rodent scent trails right up the pipe.

  • Seals the bottom opening so animals can't enter the pipe at all.
  • Won't shift, crack or degrade through seasons of weather.
  • Installs in seconds on 2x3, 3x4 and 4" round downspouts.
