John Southall, A Treatise of Buggs
“ I do admit innumerable Quantities have been destroy’d, and much good has and may be done in Summer: but should every old Bugg then be destroy’d, you are yet not safe; for the Nits behind Wainscot and in Walls, which cannot be come at, will by heat come to life, and your work is partly to be done over again.Whereas, on the contrary, if cleared out of Spawning-time, there is a certainty, as there is then no Nits, that their Offspring cannot plague you thereafter.’Tis for this Reason I warrant what I do in Winter; which I cannot pretend to do in Summer. ”
