I've recently made a small pond from half an old whisky barrel. One
small water lily, couple of good clumps of oxygenating weed and an iris.
Once the water cleared I tried introducing a couple of fish, but they
clearly weren't happy (permanently drunk and hungover, possibly?) and
have been successfully rehomed in a friend's pond.
However, although the fish weren't happy, the mozzie larvae obviously
are - there are thousands of them, and I can see that when they fledge
into grown-up mozzies I'm going to have a house full of the little
blighters.
Any suggestions how I can get rid of them safely - both dog and cat are
partial to a drink from the barrel?
