"I love being outside. Nature is one of my favorite hobbies. I like to hike. I like to kayak. I like to canoe but there is one thing that I sure don't like about being outside and that is mosquito bites. They just love me. They can't get enough of me. Well a lot of people may ask the question, why does a mosquito bite you in the first place? I'm Janice Creneti and I have been teaching environmental science for over 20 years and I'm here to answer the question why do mosquitoes suck blood? Well first of all one thing that is not commonly understood is that it is actually only the females of the species that are going after your blood. You see most species of mosquitoes, males and females when they are just trying to feed themselves, they actually eat nectar just sort of like a bee. They have to have a long tube like mouth part that is good for sticking into flowers to get pollen, to get nectar out but the female of the species needs something special when she is going to lay her eggs and that is what she gets from the human blood. She needs irons and proteins to properly form the eggs to actually be able to lay them. That is why she has to go after you and me when we are outside enjoying a Summer evening. Now the thing about mosquitoes is that they can also carry disease and that becomes a problem as they are sucking blood from one person and flying over to bite somebody else. They can even carry diseases in your pets as well. If your dog has ever gotten heart worm the mosquito is probably the culprit. So watch out for those mosquitoes, use insect repellent when you are outside and protect your pets as well. I'm Janice Creneti and this is why do mosquitoes suck blood?"
