All it does is breed mosquitoes and attract snakes.
I'm not taking chances that mosquitoes or whatever remain.
One noteworthy feature in Liberia, however, is the relative absence of mosquitoes, and the white ants and some other insect pests are not so troublesome here as in other parts of West Africa.
The absence or extreme paucity of mosquitoes no doubt accounts for the infrequency of malarial fever in the interior.
An old popular belief current in different countries, and derived from common observation, connected mosquitoes with malaria, and from time to time this theory found support in more scientific quarters on general grounds, but it lacked demonstration and attracted little attention.
In 1894, however, Sir Patrick Manson, arguing with greater precision by analogy from his own discovery of the cause of filariasis and the part played by mosquitoes, suggested that the malarial parasite had a similar intermediate host outside the human body, and that a suctorial insect, which would probably be found to be a particular mosquito, was required for its development.
He further found that only mosquitoes of the genus Anopheles had these cells, and that they did not get them when fed on healthy blood.
Mosquitoes caught by the experimenters, and sent to London, produced malaria in persons who submitted themselves to the bites of these insects at the London School of Tropical Medicine.
The result was that the houses were free from mosquitoes and no malaria occurred throughout the entire season, though there had been 40 cases in the previous year.
The alleged occurrence of the disease in localities free from mosquitoes or without their agency is not well attested; its absence from other localities where they abound is accounted for by their being of an innocent species, or - as in England - free from the parasite.
These mosquitoes or gnats - the terms are synonymous - belong to the family Culicidae and the genus Anopheles, which was first classified by Meigen in 1818.
The genus with which Anopheles is most likely to be confounded is Culex, which is the commonest of all mosquitoes, has a world-wide distribution, and is generally a greedy blood-sucker.
Mosquitoes go through four phases: (1) ovum, (2) larva, (3) nympha, (4) complete insect.
The wide distribution of certain species is undoubtedly attributable to the agency of ships and trains; under natural conditions mosquitoes seldom travel far from their breeding grounds, although the powers of flight of some species are greater than has been supposed.
Pierre shook his head and arms as if attacked by mosquitoes or bees.
