Did it just rain? Are you concerned about mosquitos (you should be!)? Dumping standing water is the MOST important thing you can do to prevent mosquitos from becoming adults (and being the bloodsuckers and disease vectors we all hate!) It only takes a tiny bit of water for eggs to be laid and hatched, so picking up trash (and tires!) is also critical to reducing this habitat. Look around, high and low for places that can hold water for as little as 3 days (those accordion-style downspout extenders are notorious mosquito breeding habitat!) and eliminate it. If you can't get rid of the standing water (e.g., bird baths, tree holes, ornamental ponds) then mosquito dunks/donuts/pellets are an option. This product, however, should NOT be used in purposely set-out buckets of water in an attempt to foil mosquitos egg-laying behaviors. It sounds like a good idea, and regularly gets posted on the internet every year, but In real world studies it was shown to actually create more egg-laying habitat, even when tended to properly. Mosquitos don't lay all their eggs in one "basket" so don't give them more "baskets"! It is important to note that Bti (the active ingredient in mosquito dunks/donuts/pellets) is a larvacide and only works if the mosquito larva eats it. It is NOT a contact insecticide, so it doesn't kill all of them in the bucket; only the larva that ingest it. The EPA and the CDC each have good factsheets about Bti and mosquito control:

Pennsylvania has about 60 species of mosquito. The risk of contracting a mosquito-borne disease has recently increased with the introduction of West Nile virus.
