![that the presence of many mosquitoes in a house is generally a sign of slovenly housekeeping, just as the presence of other vermin is, and is almost always due to the stupidity or laziness of the inmates. It has been mentioned (paragraph 5) that, as a rule, man- eating mosquitoes like to breed close to houses, and that Culex larvae live in vessels of water, and Anopheles larvae in pools. 1 he first thing to do is to search carefully in and round the house for vessels and pools of water ; and if there are many mos- quitoes in the house, we may be almost sure that we shall presently find their larvae somewhere close by. Thus Culex larvae swarm in any old tub or pot of water ; in broken bottles, old gourds, flower-pots, cisterns, garden fountains, and even in buckets of water kept for cooling soda-water or washing plates ; or in those small tins of water placed beneath the feet of tables and meat-safes to keep ants away. They may also swarm in drains and small ditches. To find the larvae, all that a person has to do is to go and look for them in places like these ; he is sure to come across them almost immediately, and will recognise them at once from the descriptions in paragraph 5. [We often find little red, worm-like creatures mixed with the mosquito larvae ; these are not mosquito larvae, but the larvae of midges.] To find Anopheles larvae we must generally go further afield. Small pools on the ground containing green water-weed, especially rain-water puddles by the side of roads and paths, are their favourite haunts; but they may also be found in puddles on the surface of roads, or in hollows in rocks, in old wells, in drains, in small ponds and rice-fields, or even in “ sloppy ” ground amongst grass, or round stables or cattle byres. To find them we must simply go and look for them ; and this should always be done if adult Anopheles are seen in the house, or even if they are not actually seen but if fresh](https://iiif.wellcomecollection.org/image/b28124698_0021.jp2/full/800%2C/0/default.jpg)
