What Can I Expect To Pay For A Bird Scarer?

Bird scarers come in all shapes and sizes. So it could be as little as under £10 or over £100. It all depends what type of birds you are trying to scare. If you are trying to scare herons away from a pond then a simple decoy will suffice.
If you're trying to scare birds away from your fields then you may need a large silent bird scarer. These units use high frequency which is good for use in built up areas. These units require an electricity supply.
Another much used method is to hang up CDs on a piece of string.
