Prior to beginning any excavation or land clearance operations
involving any major subdivision within the limits of the Township
of Willingboro, the developer shall effect a rat control program with
a pest control operator whose qualifications and experience meet with
the approval of the Township Health Officer.
One of the following rat control programs shall be used:
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 the area. 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:

Warfarin

(2) 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. 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. 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.
(3) 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 visible results of the rat control for each treatment.
(4) Note: The antidote for the anticoagulants specified is Vitamin K.
