This is, without question, the single most important step on this list, and the one most people underestimate. Mosquitoes need standing water to breed, and it doesn’t take much, even a bottle cap’s worth is enough for a female mosquito to lay eggs in. Walk around your home and check flower pot saucers, clogged gutters, unused buckets, coolers, and any container that’s been collecting rainwater, emptying and cleaning them out at least twice a week. Skip this step, and every other method on this list is essentially working against a mosquito nursery you’re inadvertently maintaining yourself.
