Why Do Mosquitoes Come Out at Night?
The mosquitoes in your yard can seem relatively absent during the day, but most of us have experienced the excessive amount of activity in the evenings, and the resulting bites we greet the next morning. So why are they so active at night, and where do they all go the next day?
Before we answer this question, we must add a caveat. Asian Tiger mosquitoes are the oddity here as they are out during the day as well. If you see larger than normal mosquitoes, with an easy-to-spot black-and-white color, you have Asian Tigers. These mosquitoes are container breeders – their favorite home is an old tire. If you want to reduce the quantity of these mosquitoes have a quick spruce up, flip pots and open containers, and check your woods for discarded trash under leaves.
For the rest of the mosquito breeds we have in this part of Texas, we don’t tend to see them during daylight hours. So why?
Much of it has to do with their size. Mosquitoes are very small, and they are unable to regulate their body temperature efficiently. Sun exposure in Texas can dehydrate a mosquito and kill it rapidly. Mosquitoes also expend a lot of energy in flight, which makes sense given their size. As a result, they must feed, and feed a lot.
It’s a common misconception that mosquitoes bite us to feed off our blood. It’s only the female that bites, and she does so only when she needs protein to lay eggs. Every time you get a bite somewhere in the yard a female mosquito is preparing to lay about 300 eggs.
Mosquitoes obtain their energy from and eat, plant nectar. During the day they head for the green plants in your yard and shelter on the undersides of leaves – keeping them fed and safe from the sun. At dawn and dusk, when the temperatures drop, mosquitoes can safely leave their hiding spots, and the females set about finding warm-blooded creatures to bite, while the males look for breeding partners.
Beyond the sun, there is also another factor that impacts the number of mosquitoes that will be out, and that is all related to water. Mosquitoes need water to survive, and we are not talking in the sense that they must drink it. Rather, mosquitoes need water to lay eggs – the life cycle of a mosquito is such that they spend the first part of their lives in water as larvae and pupae. The geography of your yard will impact your mosquito population – a creek, uneven ground, stagnant water (in a wheelbarrow, trash can, the hole at the base of the tree, and French drains, are some locations to name a few), and damp ground covered in leaf debris or pine needles all increase the presence of mosquitoes nearby.
Mosquitoes are also attracted to light. However, they will only be attracted into your yard – they won’t fly towards a bug zapper, or hover around your patio lights like moths do. Keeping your yard tidy, removing standing water and ground cover, and minimizing your bright lights will all go a long way to making your yard less hospitable. Mosquitoes have been around since the dinosaurs for good reason. If you are tired of having your evening ruined by mosquitoes, just give us a call for a free quote for mosquito control services.
