Do all mosquitoes bite?
No, it depends on the species.

Why do mosquitoes bite humans?
Female mosquitoes require a blood meal for every batch of eggs they produce. Proteins and nutrients from blood are reserved for egg production and so it is consumed only by females. Both sexes instead rely on sugar as their main source of energy. They feed on plant nectar, fruit juices and other plant liquids containing sugar. The sugar is burned as fuel and is replenished on a regular basis.

Why are mosquitoes drawn to certain people more than others?
Many factors that determine mosquito feeding behavoir are still not understood. However, these factors seem clear: Female mosquitoes use carbon dioxide as a primary cue to a person's location. A host-seeking mosquito is guided to its skin by following the carbon dioxide emitted when a host exhales. Once they've landed, a number of short range attractants are used by the mosquito to determine if the host can provide an acceptable blood meal. Folic acid appears to be important in making this determination.

Can mosquitoes cause and spread disease?
Yes. Mosquitoes are the most formidable transmitters of disease in the animal kingdom. Several of the most severe diseases (human and other) spread by mosquitoes include malaria, encephalitis, yellow fever, dog heartworm, human elephantiasis, and West Nile virus.

Do mosquitoes transmit AIDS?
No. The AIDS virus cannot survive or multiply in mosquitoes. It is digested along with the contents of the blood meal.

What happens to mosquitoes in the winter?
Mosquitoes are cold blooded and, as a result, are incapable of regulating body heat. Mosquitoes cannot function below 50 degrees farenheit. With the onset of colder weather mosquitoes enter hibernation in order to survive through the winter. Some species lay hardy eggs that survive the cold to hatch in spring, while others hibernate in various developmental stages (laval, pupal).

Does garlic repel mosquitos?
Garlic has a reputation for deterring mosquitos. Coating the skin with a garlic-based jelly has been shown to effectively repel mosquitoes and there is anecdotal evidence that eating garlic might also be effective. However, given the lack of scientific evidence available and the severity of the threats mosquitoes can pose, an additional means of control is recommended.

Are bug lights effective?
Ultraviolet bug lights, or 'zappers' are relatively ineffective against mosquitoes, who seek light colors, heat and carbon dioxide, none or which is emmitted by zappers. In addition, zappers kill indiscrimanately, eliminating insects that are beneficial, as well as those who may feed on mosquitoes.

How soon after an application can I enter the sprayed area?
