Prior to beginning any excavation or land clearance
operation involving any major subdivision within the limits of the
Township of Delanco, the developer shall effect one of the following
alternative rat control programs with a pest control operator whose
qualifications and experience meet with the approval of the Township
Health Officer:
A. Cyanide gas. Not more than one week before any particular
area within the limits specified above is excavated, the developer's
pest control operator shall gas all visible rat burrows with cyanide
gas. By means of a foot pump designed for the purpose, calcium cyanide
in a dust or finely powdered form shall be injected into the burrow
with five or six strokes of the pump. The pump shall then be used
to pump air into the burrow forcing the gas throughout the burrow
system. If gas is seen to be escaping from other holes, these holes
shall be immediately sealed.
B. Toxic bait.
(1) At least five days and not more than 14 days before
excavating any particular area within the limits specified above,
the contractor's pest control operator shall place toxic bait over
that area.
(2) Toxic bait shall consist of a suitable grain bait
in plastic bags or in paraffinized blocks containing one of the following
anticoagulants in the amount specified:

(3) The toxic bait shall be placed at the minimum rate
of one pound of bait per 400 square feet of area to be treated, placed
at the discretion of the pest control operator.
(4) The treated area shall be checked daily for a minimum
of four follow-up inspections. The toxic bait shall be renewed on
each inspection as necessary to restore the bait to its original amount.
(5) All visible carcasses of rats shall be removed and
disposed of by the pest control operator at the times of placing or
inspecting the toxic bait.
(6) The pest control operator shall submit a signed statement
to the Health Officer after the initial treatment and after each follow-up
inspection, reporting the type of anticoagulant, the form and amount
of bait placed and the visible results of the rat control for each
treatment.
