My five year old daughter wants to know why God created mosquitoes. Can you help me with this? Thank you very much.

Did you know that not all mosquitoes drink blood to survive? Some of them feed on plant nectar, even aiding in plant pollination.

Mosquitoes that do not draw blood find nutrition by feeding on plant nectar. So it seems that only a portion of mosquitoes use blood, and it is only mammalian blood. This amount would not include males since they do not consume blood. Nor would it include those few species where the females use nectar. So the percentage needing blood is under 50% of the total mosquito population. This could suggest that at some point in history a change took place that caused only some female mosquitoes to use blood as food.1

We know from Genesis 1:31 that everything God made during the Creation Week was “very good.” This certainly included mosquitoes. We can find out what mosquitoes originally ate by studying the following verses.

And God said, “See, I have given you every herb that yields seed which is on the face of all the earth, and every tree whose fruit yields seed; to you it shall be for food. Also, to every beast of the earth, to every bird of the air, and to everything that creeps on the earth, in which there is life, I have given every green herb for food”; and it was so. (Genesis 1:29–30)

Before Adam and Eve sinned, all mosquitoes used plants for food and may have had a role in plant pollination, as many mosquitos still do today. Mosquitoes certainly did not require blood for nourishment before sin entered the world. We know that mosquitoes were definitely “very good” in both design and purpose when God created them.

Unfortunately, after Adam and Eve sinned, the world changed. God’s creation became marred by sin and was no longer “very good.” That is why mosquitoes are such pests today. Some mosquitoes drink blood to survive, and can even transmit diseases.
