Product Details

About Anvil

Anvil® is a proprietary Clarke adulticide that offers superior performance for controlling mosquito populations in virtually all adult mosquito habitats. A workhorse product, Anvil formulations are products of choice for mosquito control programs conducting routine or emergency response mosquito control.

Since Clarke introduced the Anvil product line in 1999, it has proven to be a highly effective tool for combating both nuisance mosquito species and those that can vector diseases like West Nile Virus and Eastern Equine Encephalitis (EEE). This has led to its reputation as being the product of choice for the country’s most high-profile mosquito outbreaks.

  • Proven performance in emergency situations
  • Crop Tolerance Labeling for broad application flexibility
  • Effective on most common disease-vectoring species

About Anvil’s Active Ingredient

The active ingredient in Anvil® is an IRAC Class 3A synthetic pyrethroid called Sumithrin, available exclusively to Clarke for public health mosquito control products. It emulates the naturally derived, botanical insecticides, known as pyrethrins, found in chrysanthemum flowers.

In Anvil and AquaAnvil, Sumithrin is combined with a synergist, piperonyl butoxide (PBO), to enhance its ability to provide fast knockdown and control of wild mosquito populations.


Anvil and the Environment

Anvil delivers consistent and reliable mosquito control efficacy with a favorable environmental profile for wide area use.

Anvil in Sunlight

Sumithrin is photolabile, meaning that the molecule easily decomposes in the presence of sunlight. In the absence of sunlight, moderately rapid aerobic and anaerobic soil degradation occurs. The degradation byproducts are also non-persistent.

Anvil in Water

Anvil is applied in a manner that limits deposition in the treatment area, and applications will not pose a risk to healthy aquatic habitats. However, direct exposure to this product does present risk to some aquatic organisms. Please refer to the product label for specific organisms of concern and for application instruction designed to mitigate non-target risks.

Anvil in Soil

After an Anvil application, trace amounts of Sumithrin will bind to and remain in the soil, and will not transport further into plants, through the soil column, or become concentrated in the bodies of living things (bioaccumulation).

Anvil and Animals

The EPA has evaluated Anvil and determined that using it according to label guidelines, in residential areas, including in and around gardens and over non-organic agricultural crop areas, does not pose a significant risk to people or animals. Anvil has low mammalian toxicity.

Anvil and Bees

Because of the manner in which Anvil is applied and the time of day it is applied, treatments should not affect beneficial, pollinating insects, like bees and butterflies. Anvil is applied in small droplets, which break down quickly in the environment. Since the product must hit a mosquito while it is in flight to have an effect, it is sprayed at night when mosquitoes are actively flying and when other insects, such as bees and butterflies, are not active. Residues within a treatment area are not toxic.


Applying Anvil

Anvil formulations are labeled for mosquito control applications by ground or air, making it an excellent choice for a wide range of customers and habitats, including communities, golf courses, residential areas and recreational environments. The product’s crop tolerance labeling for use in and around agricultural areas also makes it a great choice for communities that surround non-organic agricultural farms.

Anvil 10+10 is often the product of choice for aerial applications, whereas Anvil 2+2 is most typically applied by ground (truck, ATV, or backpack ULV systems).  Please see the product labels for application rate guidance and other use information.

Anvil formulations are oil-based and require no excessive mixing, making it an applicator-friendly mosquito control product. The formulation is non-corroding to your application systems and has been optimized for performance through all standard ULV application equipment.

Frequently Asked Questions

What is Anvil®?
Anvil is the brand name for a line of adult mosquito control products that have been used with great success to help control adult mosquito populations for many years. Clarke introduced the EPA-registered Anvil brand of adulticides in 1997.

What is the active ingredient in Anvil?
Anvil and AquaAnvil share the same active ingredient, sumithrin. This is a synthetic pyrethroid made mimic the insect-killing (insecticidal) properties of natural substances called “pyrethrins” in chrysanthemum flowers. Anvil and AquaAnvil also contain piperonyl butoxide, a synergist that boosts efficacy at very low dosage rates.
