Some  animals can be a real pest in the garden. Their crimes include eating the wrong thing, digging in the wrong area, turning grass brown with urine and leaving a dirty mess. Some chose your favourite plants to damage as I know from some aggressive over fed pigeons in my own garden.
In my experience the worst offenders are rabbits, cats, mice, deer, pigeons and dogs including foxes. Rats cause concern but have not caused direct damage in my garden.

Animal Deterrents

• Cats and dogs scrape and dig often in the friable soil where you have planted precious seedlings. They can be frightened off with a sonic sound device like the one above.
• Scent can scare off many animals. Old wives tales of lion or elephant dung may be far fetched but Retnardine sprayed on seems to work. A crushed garlic in water spary has some short term effects.
• Rabbits and deer can be fenced out of your garden with special mesh, wire or high fences. That way the pesky blighters will go elsewhere for breakfast. Fences and hedges don’t seem to work against determined cats who always appear to prefer your garden to their own.
• Birds are scared off brassica crops by special scarers, scarecrows or more effectively by netting and string.
• Mice have eaten lots of my bulbs this year and when I plant new ones I will put a mesh over them before the soil is replaced as protection.
• Rats I have poisoned as they bred around my compost heap and I had health concerns.
• Slugs are  a whole new ball game

Sonic Repeller

I was asked about dog problems by a member of our local crown green bowling club. Apart from sonic repellers of electric fences the only answer would be a 24 hour patrol!
