I hate mosquito

I said I was satisfied after making my garden nice again the day before yesterday, but I realized that it was too early to say that because I was badly bitten by the mosquito, my legs, my arms, even my hips were bitten which still red, turgid and very itch. I had worn long sleeves and jeans. Before I went to the garden I even put some anti-mosquito spray application, so I very wondered how they manage to get there! Thank god I had put a mask on my face! I think I have served the mosquito family a big deal.
My summer is a fight with mosquitoes!
P.S. I have finished The Kite Runner and next I'm going to read Rebecca. Oh Manderly, how lovely~

I would edit your writing like this:

I hate mosquitoes!

I said I was satisfied after making my garden nice again the day before yesterday, but I realized that it was too early to say that because I was badly bitten by mosquitoes!  My legs, my arms, even my hips were bitten which are still red, swollen and very itchy. I had worn long sleeves and jeans, too. Before I went out to the garden, I even put on some anti-mosquito spray, so I have no idea how they managed to get there! Thank god I had put a mask on my face! I think I became a tasty meal for the mosquito family in my garden.  I’m afraid my summer is going to be a constant fight with mosquitoes!

Well done!  Your English writing is very good.  I just made some edits, as if I would edit any English speaker’s writing.  "Turgid" is a word that is not used very often.  Swollen is a better word because everyone would know that word, but they may not know the word turgid. 

Good for you for also reading in English.  Rebecca is a real page turner.  There was a movie made of the book in 1940 directed by Alfred Hitchcock.  You might want to see if you can find it on YouTube.  Really good and creepy!

Before I went to the garden, I even put some anti-mosquito spray application, so I very confused how they manage to get there! Thank god I had put a mask on my face! I think I have served the mosquito family a big deal. (Maybe "big blow" instead of "big deal")
