He wants the place so he kin go skinny-dippin' and slap skeeters.

Put up some purple martin houses, too. They eat skeeters just like bats do. You kin also spread old used motor oil on the top of the pond; that'll block up the skeeter larva's breathing tubes and kill them. 'Course, the EPA types might want to have a word with you if you do that, but it'll give a nice rainbow effect to the pond water.
