Mice and rats can often invade a thatched roof. Cats are a good deterrent as rats and mice will usually stay away from a house where they can detect even the slightest feline scent.
Poison is one way of dealing with rodents such as rats, but it is advisable to hire a professional rather than try to deal with the problem yourself.
A sonic ultrasound unit that emits a high-pitched noise may also work, these can be bought in most hardware stores. They are inaudible to the human ear, but are unbearable for rodents. They are environmentally friendly and require no maintenance other than a change of battery every six months.
For larger rodents such as Pine Marten’s a device called Pest Stop, from Amazon can be very effective. Pine Marten’s also hate mothballs (only the ones that smell of camphor) so placing large amounts within your attic should soon persuade them to move out. Pine Marten’s don’t like noise, so try leaving a radio on full blast in your attic to see if this will shift them. The Pine Marten is a rare and protected spices within Ireland and it is illegal to kill them. If you cannot persuade your Pine Marten to move on through the above methods you should contact the National Parks and Wildlife Service (NPWS) through their website for advice.
For birds, dummy birds of prey and bird of prey calls can be purchased in most local hardware stores, but they will require occasional moving to reduce the pests being accustomed to their presence.
For insect, it is advisable to call in a specialist to deal with insect pests such as wasps, hornets flies and honeybees. Honey bee nests should never bee destroyed but carefully relocated to help protect our local bees.
