PPQ
Spray the area surrounding the structures or the structures within
the confines of the property at least twice with a registered malathion
formulation. Make the last application after sealing the structure prior
to fumigation. Free the surface area of all debris by raking or sweeping
all debris toward the building. Include the debris in the fumigated
structure.
Notify the owner of the establishment in writing on the PPQ Form 523
(Emergency Action Notification) of the inspection requirement prior to
fumigating any structures (see “Appendix A” on page-1-A-1). To verify
success of this treatment, conduct at least three inspections of the
entire property within 1 year. In the Northeast and other cooler
regions, inspections must extend through two summer seasons when
khapra beetles are active. Allow at least 90 days to elapse between
inspections. Make the last inspection within 30 days of the time the
structure is to be released.
Category 4—Alternative Treatment
Use alternative treatments in infested properties where little or no
regulatory hazard exists (little or no chance for the pest to escape and
spread). Typically, such properties may include unused structures or
buildings, facilities that do not handle commodities or materials of
regulatory significance, or facilities that by the nature or type of
operation or for other reasons do not pose a regulatory hazard as a
result of the commerce conducted there.
Alternative treatments include either a crack and crevice or broadcast
application of a registered or exempt pesticide (including approved
cleaning and sanitation prior to treatment) and may include one or
more of the following procedures:
◆ A specified program of sanitation
◆ An extensive trapping program utilizing adult and larval traps
treated with both an attractant and an insecticide
◆ The use of bait treated with an insecticide
◆ An intensive, repeated inspection program augmented by
intensive larval and adult trapping
Apply one or more of the above treatments when the Port Director,
Plant Health Programs in Riverdale, and the responsible State
regulatory official believe treatment will result in eradication and no
regulatory hazard.
Category 5—Selective Property Fumigation Plus Alternative
Treatments
Fumigate selected structures with related usage on a single, infested
property. Apply one or more alternative treatments to all structures
which are on the property and are not fumigated.

Step 2—Issuing a PPQ Form 523 (Emergency Action Notification)
Once an infestation of khapra beetle is identified and confirmed by a
PPQ area identifier, issue a PPQ Form 523 (Emergency Action
Notification) to the owner of the premises, except when treatment is
ordered under State or county regulations. Follow instructions in
Appendix 1 for completing and distributing PPQ Form 523 (Emergency
Action Notification).
Be sure to document the treatment selected plus any alternative
treatments, inspections, and safeguards to be applied.
Step 3—Conducting Prefumigation Conference
Fumigating a structure presents problems not usually encountered in
other types of fumigations. The quantity of fumigant, supplies,
equipment needed, and the variations in building configurations make
it essential that experienced commercial fumigators and PPQ officers
conduct structure fumigations.
Arrange a meeting with the fumigator to discuss the conditions of the
treatment. Discuss the following items:
◆ An accurate measurement of the cubic capacity (volume) of the
enclosure.
◆ Fumigation schedule to be used.
◆ Adequate tarpaulin material—polyethylene or equivalent
tarpaulin of 6 mil or greater thickness.
◆ Electrical power source sufficient to operate circulation fans and
T/C unit.
◆ Gas sampling tubes—types and number.
◆ Auxiliary air pump—to quickly draw samples through gas
sampling tubes.
◆ Pedestal type fans for fumigant distribution and aeration.
◆ Sufficient quantity of fumigant for initial dosage plus an
additional amount of fumigant in case gas must be added.
◆ Commodities involved and identification of materials that may be
adversely affected by the fumigant (see Methyl
Bromide—Properties for a list of commodities). Advise the
