10 Pack Bird Repellent Rod-A Hanging Bird Repellent Rod for Viewing Spiral Control Devices, Which Can Drive Birds Away from The House Garden Swimming Pool (11.8 inches)

Installed these about 3 weeks ago, under eaves in back of house, house goes up to a peak... have aluminum siding, but the woodpeckers land on aluminum and peck up on wooden eaves, putting holes all over, and they are craping all over the siding... and it's hard to wash bird crap after being up for over 3 weeks or so... I installed these where they are hanging from peak, coming down, spaced about 10" from each other... you can tack on house or in my case, I used cable tv tacks to hammer on... these give off a good evolving reflection, spinning and twirling constantly, especially in winds... so far it's working, keeping these peckers off siding.

They have worked to keep woodpeckers off my porch

Put them all over the yard and it doesn't scare any of the various types of birds i have around away. Not a bad product. Yard looks decorated

Not sure if it helped with birds but nice to look at when wind is blowing

This product does not work at all! Bought them, placed them throughout balcony, birds never stop coming by. Money wasted!

Easy to hang , really works well

I reviewed these before and thought they were good after they hung for about two weeks. As the weeks have gone by, the pigeons sit right under the ones my husband hung. This product did not work for us.

Good
