The answer to 'why is my mosquito damage' is that mosquitoes are biting and feeding on you, causing itchy red bumps or welts on your skin. Mosquitoes are attracted to carbon dioxide, body heat, and certain chemicals on your skin, and they use their sharp proboscis to pierce the skin and drink your blood. This can lead to irritation, swelling, and even allergic reactions in some people.
To prevent and treat mosquito damage, you should use insect repellent, wear long sleeves and pants, eliminate standing water around your home, and consider professional mosquito control services if the problem persists.
