In this case, it is comprised of: a pair of maxillae, a pair of mandibles, the labrum and hypopharynx.
Labium: Fig 1. This sheath folds back as the fascicle enters the flesh of the victim. Labella: The tip of the labium contains two sensory probes, called labella, which aid the mosquito in its search for a good place to bite. This part, in conjunction with the labium, could also be described as the lips of the mosquito, which remain outside of the skin of its prey, while the fascicle is inserted beneath the skin.
Maxillae: Fig. In ants, for instance, this part would be what is used to chew through leaves. Mandibles: Fig. Imagine eating a steak: one hand mandible is holding the fork, while the other hand maxillae is using a knife to slice through the meat. Labrum: Fig. Receptors in the labrum can detect blood, as if following a scent, leading it directly to the closest blood vessel.
Once it finds and pierces a vessel, the gutter-shaped labrum sucks in the blood with the help of the hypopharynx. In this video you can see the labrum probing and, ultimately, finding a blood vessel. Hypopharynx: Fig. We use cookies to make wikiHow great. By using our site, you agree to our cookie policy. Cookie Settings. Learn why people trust wikiHow.

Choose one with a metal frame, since you'll be using magnets in this trap. With this and a few other supplies, you can create a trap that will reduce the number of mosquitoes around at least in the short term. Its effect on long-term populations is unknown, but following the advice in the breeding prevention section as well is recommended.
Use zip ties or magnets to attach a mesh screen over one side. Cover the front of the fan completely with a length of fine, insect-proof, metal mesh. Let the fan run. Whenever an area is overrun with mosquitoes, turn on the fan and let it run for at least a few hours. There will usually be a noticeable reduction in the number of mosquitoes for a day or two, although whether this translates to a long-term reduction is unclear.
Kill the mosquitoes with diluted isopropyl alcohol. Spray the solution alcohol and water on the screen to kill them, avoiding the central fan motor. You can now leave the screen of dead mosquitoes outside to feed other animals, or shake them into an exterior trash can.
The screen is reusable. Consider picking moths or other non-mosquito insects off the screen before spraying. Method 2. Spray insecticide for a temporary solution. DEET is the most effective pesticide for repelling mosquitoes, but it will only last a few hours at most, and can kill beneficial insects in your yard as well.
Check the label to see if the pesticide is approved for the intended use by the Environmental Protection Agency or another regulatory organization. Consider a mosquito-repelling plant. The one plant proven to repel mosquitoes is the lantana plant, but be aware that this can be poisonous to pets, can cause allergic reactions, and is an invasive species in some areas.
Other plants may have a minor effect, but try these only if you enjoy them in your garden or are willing to plant a large quantity: Citronella , lemon grass, any citrus fruit, basil, rosemary, mint, or catnip may all have a minor effect. Be skeptical of bug zappers and ultrasound machines. Bug zapper traps can seem effective because of loud sounds, bright lights, or sparks. However, most of the insects killed are not mosquitoes, and they can even kill insects that would normally eat or compete with mosquitoes.
These can be effective, at least temporarily. Use temporary measures. Then, like cranking open the ribcage to make room for open-heart surgery, the next two needles pull open the hole to give the mosquito space to work.
She then plunges the penultimate needle into the now-gaping gap in your skin, and starts probing until it pierces a blood vessel. But the mosquito saves the worst part until last.
The sixth appendage drips mosquito saliva into the wound:. Mosquito saliva also makes our blood vessels dilate, blocks our immune response, and lubricates the proboscis. It causes us to develop itchy welts, and serves as a conduit for dangerous viruses and parasites. This last part is how the mosquito makes life with mosquito bites so annoying.
