How do I get a flea to appear?

[HydroCupid]

hi, im struggling to get a flea. Is there any specific day or weather they appear? I've been trying for over a week now to get it. Its the last bug before I complete my critterpedia.

Available all day from April to November. They appear randomly on villagers. Listen for the bouncing sound, or if I villager mentions that they're itchy. You should see something very small hopping around over the villager's head. Good luck!

Talk to villagers and if they're itchy you're golden if not not save and exit then renter the game.
