A most efficacious means of getting rid of ants is spraying their resorts with petroleum. The common oil is worth more for this purpose than the refined. Two thorough sprayings usually suffice.
In armoires, dressing cases, etc., oil of turpentine should be employed. Pour it in a large plate, and let it evaporate freely. Tobacco juice is another effective agent, but both substances have the drawback of a very penetrating and disagreeable odor.
Boiling water is deadly to ants wherever it can be used (as in the garden, or yard around the house). So is carbon disulphide injected into the nests by aid of a good, big syringe. An emulsion of petroleum and water (oil, 1 part; water, 3 parts) poured on the earth has proven very efficacious, when plentifully used (say from 1 ounce to 3 ounces to the square yard). A similar mixture of calcium sulphide and water (calcium sulphide, 100 parts; water, 1,000 parts; and the white of 1 egg to every quart of water) poured into their holes is also effective.
A weak solution of corrosive sublimate is very deadly to ants. Not only does it kill them eventually, but it seems to craze them before death, so that ants of the same nest, after coming into contact with the poison, will attack each other with the greatest ferocity.
Where ants select a particular point for their incursions it is a good plan to surround it with a "fortification" of obnoxious substance. Sulphur has been used successfully in this way, and so has coal oil. The latter, however, is not a desirable agent, leaving a persistent stain and odor.
The use of carbon disulphide is recommended to destroy ants' nests on lawns. A little of the disulphide is poured into the openings of the hills, stepping on each as it is treated to close it up. The volatile vapors of the disulphide will penetrate the chambers of the nest in every direction, and if sufficient has been used will kill not only the adult insects but the larvae as well. A single treatment is generally sufficient.
