Devarim 7:20

הצרעה — a species of flying insect which injected poison into them, and castrated them and blinded their eyes wherever they hid themselves (Sotah 36a).

וְגַם֙ אֶת־הַצִּרְעָ֔ה יְשַׁלַּ֛ח יְהֹוָ֥ה אֱלֹהֶ֖יךָ בָּ֑ם עַד־אֲבֹ֗ד הַנִּשְׁאָרִ֛ים וְהַנִּסְתָּרִ֖ים מִפָּנֶֽיךָ׃

Moreover the Lord thy God will send the hornet among them, until they that are left, and hide themselves from thee, be destroyed.
