I have a pair of swallows trying to build a nest under the roof of my decking area. The problem here is each time they fly in or out they set off the security alarm if it is activated. I have been breaking down the nest as fast as they building it today and even tried spraying some insect spray onto the wall where they building. It helps just after I have sprayed and while the smell is still around but after a few minutes they just come back. I have now used a tine of this stuff throughout the day.
