I have one of those 210 litre green garden water butts. It's linked to automatically top up my mini pond. It has a cover and there are no mosquitos in it. I have another 2 butts just 20 feet away and they're rife with mosquito larvae.
Bob Flowerdew keeps goldfish in his water butts to eat the larvae.
When I worked in Barbados, a local Nursery owner told me they never had saucers under their plant pots as we do here as any standing water would encourage mosquitoes. I can't understand why a lidded water butt would have mossys. Greg, are the other 2 butts with lids?
No, the other 2 are not covered.
I think lids are the way to go greg
they will breed in any standing water,they will get in any tiny opening and water left lying about in pots or buckets will encourage them to breed that s why its important to empty any water lying about in pots and empty the water butt ever so often.
A layer of oil, just a drop, it spreads across the top and they can't get their breathing apparatus through it and suffocate
I agree, in the US they have a constant battle with the mossy that spreads Dengue fever, luckily it only moves North about 100 yards a week I think. I believe that there and in parts of Africa they use a spray that changes the surface of the water. It stops them from reproducing.
Here in the Fens, historically, there was a form of malaria and the Fen people grew Opium Poppies to combat the disease.
I've put an old pair of black tights over the top of my water but, its stopped all creatures and flies dropping in
yes that's what I do too!
I'd love to see a photo of that
My water butts both have lids on but the water smells like rotten eggs, could I try the citronella oil in them Napo?
Potassium permanganate from the chemist will sweeten the water. Not tried citronella, not sure you could water plants with citronella
Thanks Anonimouse I'll get some of that.
I wash my bird bath out quit often as it gets quite mucky looking with them all washing in there. Then they drink their own bath water
Having a lid on your water butt will also stop and bees falling in and drowning. Never mind any other inquisitive creatures
