Swallows are talented birds and can build a nest in as little as 24 hours and do so building some very impressive mud nests!
Below are some steps to take to prevent these birds from making your premises or boat their home;
1. Only when nests are vacant, fully remove and use a hospital grade cleaning solution to thoroughly clean all droppings and feathers and consider adding a fresh coat of gloss paint over the surfaces. Gloss paint makes it more difficult for the mud to stick. Bleach affects their sense of smell and removes the smell of their pheramones.
2. Find the correct deterrent to stop them returning.
The Hawk Laser 80mW, Bird Laser, Quadblaster QB4 or Super Quadblaster QB4 and Ultrason -X have been found to be excellent deterrents. For smaller areas of less than 20 meters, the Balcony Guard ,Yard Sentinel RC and Optical Gel discs (spaced a maximum distance of 15 cm apart) are also effective.
4. Close doors 1 hour prior to sunset to prevent access to roost. The doors can then be re-opened after dark.
5. For boats we find a mixture of Ultrasonics and the Prowler Owl work brilliantly. Placing a Prowler Owl on the front and back of your boat and a Balcony Guard or Solar Boat Guard kit positioned along the railings is optimal.
Although great for farms due to their ability to eat massive amounts of insects that affect crops, these birds can also be damaging pests once they decide to home in barns and warehouses and they do so in very large numbers!
The fouling of these birds often damages machinery, produce, infrastructure and recreation areas due to their diseased droppings which also contain mites and insects that can bite humans too.
Swallows are a protected species and it is recommended you contact your local government agency to ask about the removal of nests during nesting/egg laying season.
