Exodus 8:12-17

12So Moses and Aaron went out from Pharaoh, and Moses cried to the Lord about the frogs, as he had agreed with Pharaoh.
Or which he had brought upon Pharaoh
13And the Lord did according to the word of Moses. The frogs died out in the houses, the courtyards, and the fields. 14And they gathered them together in heaps, and the land stank. 15But when Pharaoh saw that there was a brespite, he chardened his heart and would not listen to them, as the Lord had said.

The Third Plague: Gnats

16Then the Lord said to Moses, “Say to Aaron, d‘Stretch out your staff and strike the dust of the earth, so that it may become gnats in all the land of Egypt.’” 17And they did so. Aaron stretched out his hand with his staff and struck the dust of the earth, and ethere were gnats on man and beast. All the dust of the earth became gnats in all the land of Egypt.
