Catchmaster Oasis Ovi-Mini Mosquito Trap (4-Pack)

This is the pilot's headline pick, and it's the off-the-shelf take on the gravid-trap idea: give an egg-laying female what looks like the ideal nursery — a small, dark, water-holding chamber — and she commits to it instead of your plant saucers. Once she lands to lay, an adhesive surface holds her for good, so the eggs she was carrying never become next month's swarm. No airborne pesticide, no propane, no power cord — it targets exactly the container-breeding species (Aedes albopictus, Culex pipiens) that dominate NYC backyards. It ships four to a box, which is the whole point: one trap is a science experiment, four ringing a yard is a strategy, and a block running dozens is the pilot.
