Exodus 10:4-6

10:4 But if you refuse to release my people, I am going to bring locusts into your territory tomorrow. 10:5 They will cover the surface of the earth, so that you will be unable to see the ground. They will eat the remainder of what escaped – what is left over for you – from the hail, and they will eat every tree that grows for you from the field. 10:6 They will fill your houses, the houses of your servants, and all the houses of Egypt, such as neither your fathers nor your grandfathers have seen since they have been in the land until this day!’” Then Moses turned and went out from Pharaoh.

Exodus 10:13-15

10:13 So Moses extended his staff over the land of Egypt, and then the Lord brought an east wind on the land all that day and all night. The morning came, and the east wind had brought up the locusts! 10:14 The locusts went up over all the land of Egypt and settled down in all the territory of Egypt. It was very severe; there had been no locusts like them before, nor will there be such ever again. 10:15 They covered the surface of all the ground, so that the ground became dark with them, and they ate all the vegetation of the ground and all the fruit of the trees that the hail had left. Nothing green remained on the trees or on anything that grew in the fields throughout the whole land of Egypt.
