Yes! There are certain mosquito species that tend to breed in artificial containers, tires, tree holes and such. These mosquitos tend to stay close to humans, and with a ready blood meal available, don't need to frequently leave the area to complete the process of repopulating. Even small quantities of water can provide ample breeding opportunity for these species. A plastic bottle cap can be the home to several mosquito larvae. Some species are more apt to breed in natural environments such as ditches, swamps and low areas. These are more difficult for the homeowner to control and only physical means such as screens, long sleeves, repellents and such may be the only defenses in the absence of an effective mosquito control program.
