Wasps should be sedulously destroyed during April, May, and June, for all appearing in these months are queens, and the foundresses of nests. Their favourite resort at that season is the laurel, for the sake of the honey secreted by the midribs of its leaves. They may then be caught in the hooped gauze net of the entomologist. In August, wasps' nests should be destroyed, and spirit of turpentine is the best agent that can be employed for the purpose. The mode of using it when the nest is in the earth has been thus detailed. Put some of the turpentine into a large bottle, shaking it about until the whole of the inside is wetted by it; then fix the neck of the bottle in the nest's entrance, and place over it a large flowerpot. By replenishing the bottle with turpentine once or twice, the whole of the wasps will be destroyed by the fumes. - Gard. Chron.

If the nest be in a place where the bottle cannot be employed, the spirit may be injected by a syringe, and the fume retained by covering up the nest's mouth.
