FOR MORE EFFECTIVE
MOSQUITO CONTROL
Clarke provides you with two choices for controlling a
wide range of mosquito populations effectively and efficiently:
Anvil® and AquaAnvil™. Both contain the same active
ingredient, Sumithrin®, a pyrethroid. One formulation gives
you traditional oil-based solutions for highly effective ground
and aerial applications; the other provides an effective
water-based alternative to meet growing community needs
for green or sustainability initiatives. Both Anvil and
AquaAnvil can be applied neat or diluted.

Nerve Axon with
Pyrethroid Present
Sumithrin®, d-Phenothrin, is
an insecticide that acts on an
insect’s axons in the peripheral
and central nervous systems
by disrupting the sodium
channel complex. This sets off
a nerve reaction that ultimately
leads to pest mortality.

Benefits of Pyrethroids
The active ingredient in Anvil® and
AquaAnvil™ is a pyrethroid called
d-Phenothrin (brand name Sumithrin).
It emulates the naturally derived
insecticides known as pyrethrins, found
in chrysanthemum flowers. In Anvil
and AquaAnvil, d-Phenothrin is
combined with a synergist, piperonyl
butoxide (PBO), to enhance the
active’s ability to provide fast knockdown and control.
Registered for use by the U.S.
Environmental Protection Agency in
1975, d-Phenothrin biodegrades rapidly
in the presence of sunlight and/
or microorganisms.
As a result, Anvil and AquaAnvil
are excellent choices for:
» Inhabited outdoor areas —
municipalities, residential, parks,
camp grounds, golf courses
»A
reas that surround recreational
facilities — woodlands, swamps,
marshes, overgrown areas

EVOLUTION OF SUMITHRIN®
PROVIDING MORE
EFFECTIVE CONTROL
AFTER 30+ YEARS
Natural pyrethrins were developed for adult insect
control in the 1950s. This was soon followed by development
of pyrethroids, including d-Phenothrin. Registered by the
EPA since 1975, Sumithrin (the name brand for d-Phenothrin)
has been used extensively throughout the world for
protection against public health insects, noxious household
insects, stored grain insect pests and for dis-insecting
commercial aircraft. From simple nuisance control labeling,
to aerial application, to water-based formulation, and
now to crop tolerance labeling, the evolution of Sumithrin’s
usage continues!
A History of Effectiveness for Emergency Use
The use of Anvil® and AquaAnvil™ with Sumithrin
has played an important role in many high-profile
mosquito outbreaks, including environmental disasters
and mosquito-borne disease. Beginning in 1999, Anvil
was used following hurricanes Dennis and Floyd.
Throughout the next 11 years, Anvil has been used for
the suppression of West Nile virus and Eastern Equine
encephalitis throughout the country including New York
City, Chicago, Maricopa County in Arizona, Plymouth
and Boston. Additionally, in many post-hurricane and
flooding situations, such as hurricanes Katrina and Rita,
Anvil applications have proven successful.

DROPLET OPTIMIZATION
TECHNOLOGY (DOT)
ENHANCES EFFICACY
Droplet Optimization Technology provides optimal
stability for AquaAnvil’s™ active ingredient particles and
protects them from evaporation within the droplet.
As a result, a more concentrated, more effective droplet
is delivered. This consistent performance results in
higher kill rates.
How DOT Results
in Better Performance
The DOT formulation of AquaAnvil
allows larger active particles to be
present in an optimized spray droplet.
As the droplet leaves the spray
nozzle, the aqueous carrier begins
to evaporate until it reaches an
optimized droplet size. At this point,
evaporation ceases and the droplet
is stabilized.
When airborne, a water-based droplet
will lose about 50% of its volume
immediately after it is released from
the nozzle. In AquaAnvil, the “DOT”
droplet becomes more concentrated
as the water evaporates. This phenomenon makes AquaAnvil effective by
ground and air.

Environmental Toxicity
In Sunlight: d-Phenothrin is photolabile,
i.e. the molecule easily decomposes in
the presence of sunlight. The half-lives
of d-Phenothrin in water in the presence of light range from 9.1 to 13.9 hours
depending upon the location of the
radiolabel. The degradation products
of d-Phenothrin are nonpersistent.
Moderately rapid aerobic and anaerobic
soil degradation was found in the
absence of sunlight. The half-lives for
d-Phenothrin in aerobic soil ranged
from 18.6 to 26.0 days, depending upon
the location of the radiolabel.
In Soil and Water: d-Phenothrin is
not readily transported from the site
of application. Very little movement
of d-Phenothrin and its degradation
products from soil into plants or
through soil columns was observed
using radiolabeled material.
d-Phenothrin hydrolyzes in water, or
breaks down into lesser components,
at pH of 9 or greater. d-Phenothrin
does not bioaccumulate and is subject
to both oxidation and cleavage of the
ester linkage in biological systems.
On Nontarget Species: Studies
conducted in the absence of sunlight
found the 96 hour LC50 for fish ranged
from 17 to 200 μg/liter. The 3-hour
LC50 for daphnia was 25–50 mg/
liter. The LD50 for bobwhite quail was
greater than 2500 mg/kg body weight
and the LD50 was 5000 ppm of diet
for the bobwhite quail.

application methods
optimized for your
equipment
Anvil® 10+10 and AquaAnvil™ are proven effective whether
applied by air or ground (truck, ATV, backpack). Anvil 2+2
is primarily used for ground applications. All formulations have
been optimized for all application equipment and nozzles, and
they are non-corroding to your application apparatus.
Applying Anvil 10+10 and AquaAnvil by Air
Aerial applications can be completed
with fixed wing or rotary aircraft. Using
Anvil 10+10 at a rate of .62 fl. oz/acre
or AquaAnvil at .54 fl. oz/acre delivers
maximum mosquito control coverage
over a wide area. Droplet VMD (volume
median diameter) should be optimized
for aerial application as follows:
» Anvil 10+10:
VMD between 30–35 microns
» AquaAnvil:
VMD at 30–35 microns. Droplet size
influences the evaporation process
that reduces the droplet’s volume
after atomization
In wind tunnel atomization studies, Anvil
and AquaAnvil have shown to effectively
produce this droplet size range when
sprayed through equipment that has
been correctly calibrated.
To Optimize Your Aerial Application:
1
Select the Proper Nozzle
Refer to the table to achieve
droplet VMD between 30–35 μm
for Anvil and AquaAnvil. Some
of the best nozzles for Anvil and
AquaAnvil usage are rotary
(e.g. Beecomist or Micronair). Be
aware that conventional agriculture
nozzles, or flat fan nozzles, may
not produce droplets within the
appropriate size spectrum.

Droplet Dynamics
To achieve maximum performance,
droplets can be collected and measured
by utilizing a rotary impinger equipped
with slides.
» Droplet VMD should be optimized
to less than 30 microns. Use Tefloncoated slides in the spinner
For best results when characterizing
aircraft, it’s recommended wind speeds
be between 1–8 mph. Droplets on slides
can be measured using a compound
microscope with a mechanical stage
and an ocular micrometer.
Starting at one end of the slide, measure
each droplet as they pass through the
eyepiece micrometer. A minimum of
200 droplets should be measured to
obtain an adequate sample. Make necessary adjustments to spray apparatus
to achieve desired droplet size.
» Anvil 10+10 is 0.63
» Anvil 2+2 is 0.57
» AquaAnvil is 0.65
Use these factors until the spread
factor is confirmed.
To Determine Appropriate Offset:
» Place droplet collectors 50 ft apart
and 90 degrees to the wind direction
(Fig. A)
(Fig. A)
» Fly directly into wind over slides at
an altitude that will allow maximum
droplet collection for characterization
purposes. Spray for 15 seconds after
passing over slide collectors**
» Wait 10 minutes after application for
upwind droplets to reach collectors
*
Determined by Dr. E.J. Beidler, 2009

To Optimize Your
Ground Application:
To achieve maximum performance,
droplet VMD should be optimized
at between:
» 1 5–20 microns for Anvil and AquaAnvil
Droplet spectrum may be determined
by using the hot-wire method using
a DCIII (AIMS) unit that measures droplet ranges. Application equipment must
be tested at least annually to confirm
that pressure at the nozzle and nozzle
flow rate(s) are properly calibrated.
When using non-thermal ULV portable
backpack spray units, apply at a walking
speed of 2 mph, making sure that the
same amount of active ingredient is
applied per acre. Use a 50 ft swath for
acreage calculations.
Always read and follow label directions.
Standard Droplet Collection:
Standard Droplet Measurement:
For Anvil formulations and AquaAnvil,
use standard Teflon-coated microscope
slide. Then proceed as follows:
» Use a compound microscope
equipped with a mechanical stage
and an ocular micrometer placed
in the eyepiece
» Attach slide to 3 ft–4 ft rod
» Stand 10 ft–25 ft downwind
from nozzle
» Distance is dependent
on sprayer velocity
» Higher velocity of sprayer =
further distance from nozzle
(not to exceed 25 ft)
» Swing rod (with coated slide
facing the insecticide) once rapidly
in a baseball swing/diagonal motion
toward the sprayer, through the
spray cloud
» Starting at one end of the slide,
measure each droplet as they pass
through the eyepiece micrometer
» A minimum of 200 droplets
should be measured to obtain
an adequate sample
» Spread factors for the following
are as follows:
• Anvil 2+2 = 0.57
• Anvil 10+10 = 0.63
• AquaAnvil = 0.65

Anvil and AquaAnvil should be applied when conditions are favorable for ULV applications. Favorable application
conditions occur when the atmosphere at application height to immediately above ground level is stable. This condition
is characteristic of an inversion, which occurs when temperatures increase with height. Never apply above an inversion.
Droplets will not reach the ground. Stability is also influenced by solar radiation and heat exchange between air, soil
and vegetation. As a result, favorable conditions for ULV applications usually occur prior to sunrise and after dusk. Anvil
and AquaAnvil have been shown to have a negative temperature coefficient. This means it is extremely effective, early
and late season when temperatures are between 50°–65° F and most mosquitoes are active.

frequently
asked questions
Q: What are Anvil® and AquaAnvil™?
A: These are names of adult mosquito
control products which have been
used with great success to help
control adult mosquito populations
for many years.
Q: How soon can a family go outside
after an application?
A: There are no re-entry precautions
or limitations for Anvil or AquaAnvil.
Both degrade rapidly in the environment and do not bio-accumulate.
Q: What is the active ingredient
in both products?
Q: How will this spraying affect the
mosquito population?
A: Anvil and AquaAnvil share the
same active ingredient, d-Phenothrin,
which is also known by the brand
name Sumithrin®. This is a pyrethroid
similar to natural pyrethrins that are
extracted from chrysanthemum
flowers. Anvil and AquaAnvil also
contain piperonyl butoxide, a synergist
which boosts efficacy at very low
dosage rates.
A: In the majority of spray
applications, spraying with Anvil
or AquaAnvil is highly effective at
killing adult mosquitoes in the
treated area.
Q: Does either Anvil or AquaAnvil
pose a health risk to humans?
A: All pesticide products involve a
balance between risks and benefits.
The active ingredients in Anvil and
AquaAnvil have been carefully tested.
They are registered for ground and
aerial application in outdoor residential and recreational areas.
Q: How is Anvil applied?
A: Generally, Anvil and AquaAnvil are
applied from the air or ground at an
ultra low volume in an extremely fine
mist of tiny drops, where the average
droplet size is 17 microns, smaller than
the size of a pinhead.
Q: How much is typically applied?
A: Anvil and AquaAnvil are applied
in very low dosages, as low as
6 tenths of an ounce per acre.
An acre is the equivalent size of
approximately a football field.
Q: How effective is Anvil and
AquaAnvil? How many mosquitoes
does it kill?
A: The active ingredient in Anvil and
AquaAnvil, d-Phenothrin, has proven
to be extremely effective in killing
mosquitoes worldwide for over
20 years. Anvil and AquaAnvil
have been tested in over 50 natural
population and caged field trials in
the United States against 30 different mosquito species. As with any
adulticide, environmental conditions,
droplet size and the weather might
affect results.
