A treatise of buggs [electronic resource] : shewing when and how they were first brought into England. How they are brought into and infect Houses. Their Nature, several Foods, Times and Manner of Spawning and Propagating in this Climate. Their great Increase accounted for, by Proof of the Numbers each Pair produce in a Season. Reasons given why all Attempts hitherto made for their Destruction have proved ineffectual. Vulgar Errors concerning them refuted. That from September to March is the best Season for their total Destruction, demonstrated by Reason, and proved by Facts. Concluding with directions for such as have them not already, how to avoid them; and for those that have them, how to destroy them. By John Southall, Maker of the Nonpareil Liquor for destroying Buggs and Nits, living at the Green Posts in the Green Walk near Faulcon-Stairs, Southwark.
