What this site is

The guides here are general information written from experience of selling and fitting these products. They are not professional advice about your building, your site or your legal position.

For anything that matters, take advice from someone qualified: a pest management professional for a serious infestation, a builder or roofer for work at height, an electrician for anything near wiring, and a lawyer for a question about consents or a boundary.

What the products do

They are physical deterrents. A spike strip removes the flat surface a bird needs to land and turn on, netting closes a space, and gel makes a surface unpleasant to stand on.

We do not claim that any product is completely effective, and we say so on the product pages rather than only here. What a deterrent achieves depends on where it is fitted, how much of the surface is covered, and whether the birds have another reason to be in the area. Treating one ledge and leaving the next one moves the problem rather than solving it.

What we do not claim

• We publish no effectiveness percentage for any product.
• We publish no service life in years, because the site and the fixing decide it rather than the product.
• We sell no warranty and do not describe one.
• We make no health claim of any kind.

Wildlife and the law

Most wild birds are protected by the federal Migratory Bird Treaty Act, and that protection covers the nest and the eggs as well as the bird. Native birds are absolutely protected along with their nests and eggs; introduced species such as the house sparrow, the starling, the common myna and the feral pigeon are not. If you are unsure which bird you are dealing with, take advice before doing anything.
