Bird Spikes: Do They Work for Pigeons and Crows?

Spikes deter perching on ledges.

The short answer

They discourage landing on narrow ledges and railings when correctly fitted but are not effective in open areas or when birds build nests over them. They work best with nets and cleaning.

Where they work

• Ledges and railings.
• Signboards.

Limits

• Birds may build nests on them.
• Not for balconies with open space.
• Need regular cleaning.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.

Frequently asked questions

Are they cruel?

Designed to deter, not harm.

Do crows get deterred?
