=The Earwig.=--Among the most tiresome of pests is the earwig. The bar-framed hive seems to suit its requirements in every particular, and an opportunity is apparently never lost by it to enter and take possession. Any empty combs that may lie within its purview are immediately commandeered for its own particular purposes--even when combs are kept for warmth in a super or section crate on the quilt inside the hive they are not safe from the ravages of this pest. Its eggs are deposited in the cells and the combs rendered useless. One of the best traps for catching earwigs is the old-fashioned one of a plant-pot filled with moss and placed upside down on the end of a stake. The pot and its contents should be dropped into boiling water at regular intervals of a few days. =Mice.=--Both house and field mice are included in the bee-keeper's black list. Their raids are seldom made in summer-time, especially if the hives are up to strength, but in winter it is no uncommon occurrence to find them in possession of a hive. It is probably the sweet scent and suggestion of warmth that first attract them to explore the hive, but once inside they begin the work of devastation. They are keen after the farinaceous pollen and demolish the combs to get to their stores. The only effective way to prevent the entry of mice is to place a piece of zinc perforated with holes just large enough to admit the passage of a bee, along the entrance to the hive to a height of 3/16 of an inch. =Moths.=--Moths of various kinds choose the hive as a suitable place in which to deposit their eggs, and the bee-keeper has need to keep a sharp lookout for the first evidence of their visitation, for, if not dealt with promptly, disaster is sure to follow. They generally deposit their eggs in loose bundles among the combs, and immediately the grubs are hatched they commence operations on the cells, which are rendered useless by their perforations. The sawgate of the frame is a favourite lodging of the moth, and the skep hive, of course, is a happy hunting ground for it. The old-fashioned remedies--lavender flowers and camphor--are still esteemed the best for warding off moths, though naphthalene and chemical solutions are without doubt equally effective. =Ants.=--The fondness of ants for sweet things is sufficient explanation of their raids on the hives. Where they are numerous it is advisable to stand the legs of the hive in tins containing paraffin oil: this is an effective means of preventing their climbing into the hives.
