Not long ago the kitchens and bakeries of the Fir Vale Union Workhouse at Sheffield swarmed with blackbeetles, to such an extent that the Government Inspector feared the buildings would have to be pulled down. The insects even got into the soup and bread provided for the inmates, in spite of all vigilance and every remedy. The Board of Guardians, in despair, consulted the curator of the Sheffield Museum - Mr. Howarth, F.Z.S. - and he invented a paste which in a short time completely freed the workhouse from blackbeetles. This "Union" cockroach paste can be had in tins from Mr. Hewitt, chemist, 66 Division Street, Sheffield. It never fails in its effect.' 'Keating's Powder' is also effectual if the beetles are swept up in the morning and destroyed.
