In Connecticut, the deadliest creature is common White-Tailed Deer, cause people in cars are killed when they hit them. But worldwide - it's Mosquitos! Our ponds can be a haven for deadly mosquitos. Read the story (by clicking on the picture or title) to find out what you can do to eliminate mosquitos from your ponds and water features. Story submitted by Ralph Smith, aka 'Smitty' from Southwest Koi and Pond Association, El Paso, TX.
Have you ever wondered which creature is responsible for killing the most people?
Perhaps a shark? Maybe some type of snake or spider? Or maybe some sort of large land mammal like a grizzly bear or a lion?
If you were thinking along those lines, then I’m sorry to disappoint, but the deadliest animal known today is quite a bit smaller than all of those. Believe it or not, found almost everywhere, on every continent except Antarctica, our deadliest creature is the mosquito!
Presenting: The mosquito.
How is this possible?
Mosquitoes are notorious for transmitting diseases. They carry with them diseases like malaria, dengue fever, yellow fever, encephalitis, West Nile virus, and countless others. Acting as vessels for diseases, mosquitoes transmit these diseases to either us, or animals. These diseases can then make us very ill and sometimes even lead to death. It is not actually one type of mosquito that is transmitting all of these diseases, but in fact, it’s several. The most common belong to the genera Aedes (Dengue and Yellow Fever), Anopholes (Malaria and Canine heartworm), and Culex (West Nile, Encephalitus and Avian Malaria).
At more than 1 million fatalities each year, the mosquito is most certainly the deadliest.
Why They Bite
Mosquitoes need the protein in our blood, or the blood of other animals, in order to lay their eggs. This means that only the female mosquitoes need blood. In other words, next time you ﬁnd yourself scratching away at one or more of those incredibly itchy and annoying mosquito bites, you can thank female mosquitoes for that. The male mosquitoes are content living oﬀ plant nectar.
The way a female mosquito bites us is by sticking her thin, sharp proboscis into our ﬂesh. As she draws blood she inserts some of her saliva along with anticoagulants to keep the blood from clotting. This is where the danger lies and gives mosquitoes the rightful title of being the most deadly. In the mosquito saliva there could be viruses and parasites lurking, ready to infect us. These diseases can be deadly, but are not normally transmissible between humans. However, mosquitoes are doing an excellent job acting as vectors for transmission of these diseases.
But how exactly do the mosquitoes ﬁnd us?
Mosquitoes have several diﬀerent ways to sense living things so that they can then bite and extract blood. The ﬁrst of those is chemical sensing. Mosquitoes can actually detect CO 2 in the air from about 100 feet away. As we and other animals around us exhale, mosquitoes are alerted of our presence.

So maybe we can just hold our breath next time we see a mosquito? Well, it’s not quite that easy. Mosquitoes can also detect heat and have visual sensors that can detect color contrast and movement.
- Wear long sleeves & pants.
- Put on mosquito repellents that contain DEET.
- Avoid being outside during dawn, dusk, or late evening.
- Eliminate stagnant water. Stagnant water attracts mosquitos & gives them a good place to lay their eggs.
- If you have a pond, consider stocking it with Gambusia, which feed oﬀ mosquito larvae.
As irritating as these insects can be, they have been around for a whole lot longer than us – about 30 million years. So, it seems inevitable that we must learn to exist with them, but it doesn’t hurt for us to have some kind of upper hand to protect ourselves
Note from Karen: Also, turns out that mosquito larvae has a hard time hatching in disturbed water - so splashy waterfalls and fountains can help reduce mosquitos too!
