Exodus 8:15

13The LORD did according to the word of Moses, and the frogs died out of the houses, out of the courts, and out of the fields.

14They gathered them together in heaps, and the land stank.

15But when Pharaoh saw that there was a respite, he hardened his heart, and didn’t listen to them, as the LORD had spoken.

16The LORD said to Moses, “Tell Aaron, ‘Stretch out your rod, and strike the dust of the earth, that it may become lice throughout all the land of Egypt.’”

17They did so; and Aaron stretched out his hand with his rod, and struck the dust of the earth, and there were lice on man, and on animal; all the dust of the earth became lice throughout all the land of Egypt.
