It may be destroyed by syringing witli a solution of caustic / potash—say two table spoons'ul : , to gallon of water, or with a little' thin'\ solution of soft soap. The former is preferable, but either must be applied •freely, and in all probability two or tliree applications would lie required on account of tbe largo number of eggs deposited by the' female, and the impossibility of destroying every individual by a syringing, i I am, &c,,: T.
