Scratching feet when I trimmed the mountain from the back of my house (3)

Description: I was cleaning the back of my house by thinning the grass a little since it was very high, but as i was wearing shorts and flip-flops, something mounted on my feet and legs and it began to itch, so i stopped cleaning and began to scratch my feet and legs, but i felt that it did not go away, no matter how much i scratched the itching, it went on and on
