Mosquitoes have become big trouble for several reasons. First, mosquito transmites epidemics to the people. Because the summer is coming, there are many mosquitoes which are infected by Japanese encephalitis. Second, mosquitoes disturb my sleeping at night. Because they fly around my ears and make noisy, it irritates me. After Mosquitoes bite my arms and legs, the spot is really itch and swells up. Finally, mosquitoes take my most valuable things from me. It costs me a lot of money to buy mosquito repellent, spray, and mosquito net. Because money is most important thing in my life, I have to save my money and refrain myself from spending money.
