Adult Mosquitoes are a problem because the females require blood to lay their eggs. This affinity for blood gives mosquitoes the potential to transmit disease. Mosquito eggs laid by each female can number in the hundreds. Eggs can be laid in the soil of temporarily flooded areas such as floodplains or on the water's surface. Mosquito Pupae are the last stage before mosquitoes become flying, biting adults.
Pupae also require a constant water source and at least a day to mature.
Mosquito Larvae require a constant water source to mature. If the weather is warm they can mature from egg to pupae in less than a week. Keep swimming pools maintained properly by proper chlorination and working equipment. Keep rain gutters cleared of debris. Keep vegetation in and around ornamental ponds thinned and minimize mosquito production by adding mosquito fish.
