Hello, First we had Mallards messing up the pool..now we've got a pestier problem. We opened the pool early last week and put the solar cover on it Thursday (this is Saturday) -- Friday I came home from work --made sure the ducks were still gone and then discovered we have some kind of non-flying beetle by the dozens all around the edge of the solar cover on the deep end -- they are about the size of a pin head and some a little bit bigger -- dark in color --they look mettalic in the water--kind of copperish and are round in shape. They do NOT hop or fly or dive down in the water, just float on top and crawl all over the solar cover. Today I have a lookie-see and OMG!!!! there is a small colony growing fast!! Plus..they are not just in the pool but on the sidewalk and in the grass and not just by the pool either -- I think they came from the yard and went to the pool--- yikes!!! We had some Malathyon that we used on red spider mites that I experimented with (on land of course--never in the water) and it didn't hurt them at all. I've spent hours looking at tons of different types of beetles and have found nothing that looks like these things. Oh yeah..The friggin ducks are back too!!

They are pretty but they have to go away...fakes snakes do not work--neither does spraying them with the garden hose..I think they like it. I'm gonna try that flashing light floating in the pool next if I can find out where to buy one. This is looking like an interesting pool year.
Sorry this is so long -- so I guess I have 3 questions.
Does anyone know WHAT they are

and more importantly how to kill them -- on land and on "sea" --so-to-speak?
How do you REALLY keep the ducks away?
