Bendiocarb

What is bendiocarb?

  • Bendiocarb belongs to a class of insecticide known as carbamates.
  • Bendiocarb was withdrawn from use in the United states in 2001 but is still available here in Britain. That may soon change.

What is bendiocarb used for?

  • In pest control bendiocarbs are used to control a wide range of insects such as beetles, spiders, aphids, mites, wasps, cockroaches and ants.
  • Bendiocarb may be licenced for both indoor and outdoor use.
  • Products containing bendiocarb are usually formulated as dusts and powders so are mainly targeted at crawling insects.

How does bendiocarb work?

  • Bendiocarb disrupts the normal functioning of an insect's nervous system and may kill by either contact or ingestion.
  • Bendiocarb disrupts the nervous system by interfering with an enzyme necessary for normal nerve transmission.

Which of our products contain bendiocarb?

How toxic is bendiocarb?

  • Bendiocarb-containing products are low to moderate in toxicity. The pure chemical is highly toxic. The formulated products are typically lower in toxicity because of the reduced concentration of
    bendiocarb.
  • Bendiocarb is moderately to highly toxic to both male and female rats. Bendiocarb is highly toxic to
    guinea pigs and rabbits.
  • When researchers applied bendiocarb to the skin of rats, they found it to be moderately toxic.

What effect does bendiocarb have on wildlife?

  • Pure bendiocarb is highly toxic to birds such as ducks and quail.
  • Bendiocarb is highly toxic to honey bees.
  • Bendiocarb is also extremely toxic to earthworms, reducing a population over 90% in one study in which bendiocarb was applied at a standard rate.
  • Bendiocarb is also moderately to highly toxic to several species of fish and aquatic invertebrates such as shrimp, crabs, and insects.

Signs of toxicity in humans.

  • Early symptoms associated with bendiocarb exposure may include headache, malaise, muscle weakness, nausea, gastrointestinal cramps, sweating, and restlessness.

Boric Acid

    What is boric acid?

    • Boric acid is derived from boron, a naturally occurring substance found in rocks, soil, and water. Boron is common in the environment.
    • Boric acid is generally a white solid, but it may be clear to murky. It is odorless and generally stable under normal conditions.
    • Boric acid naturally occurs in air, water (surface and ground water), soil, and plants, including food crops. It enters the environment through break down of rocks, loss from seawater, and volcanic eruptions.

    What is boric acid used for?

    • Boric acid and salts of boric acid are active ingredients of pesticide products used against insects, spiders, mites, algae, molds, fungi, and weeds.
    • Boric acid pesticides exist in various forms including aerosols, liquids, granules, wettable powders, dusts, pellets/tablets, and impregnated materials (baits, stakes, etc.).

    How does boric acid work?

    • Insects are killed by eating boric acid and its salts. The salts of boric acid are abrasive to the exterior of the insect.
    • Boron is an essential plant nutrient, and some boric acid products are used to aid plant growth.
    • Plants need small amounts of boron but high levels are toxic.
    • Boric acid kills weeds by disrupting normal plant functions and causing water loss.
    • Boric acid interferes with reproduction of molds and fungi.

    How toxic is boric acid?

    • Boric acid is very low to low in toxicity when eaten.
    • Boron compounds are low to very low in toxicity when inhaled.
    • Boric acid is low in toxicity when applied to the skin. It is poorly absorbed in rabbits across intact skin, but damaged skin experiences increased penetration.
    • Boric acid is classified as low to very low in toxicity for skin irritation.
    • Boric acid is generally low in toxicity for eye irritation. An exception is a specific boric acid salt, which is highly toxic to the eye.
    • In a 90-day study, investigators fed dogs boric acid. At the highest dose, they noted altered blood chemistry, a buildup of fat in select tissues, and toxicity to the testes.
    • Researchers fed dogs boric acid in the diet for 2 years and detected no adverse health effects.
    • Signs of toxicity in laboratory animals poisoned with boric acid include depression, impaired muscle movement, vomiting, purple-red skin color, and lowered body temperature.

    What effect does boric acid have on wildlife?

    • Boric acid is practically nontoxic to fish and other water organisms. Boric acid has a low potential to buildup in organisms.
    • Boric acid is practically nontoxic to birds. Boric acid may adversely affect development of young birds. In studies with ducks, the highest tested doses in ducklings caused increased mortality, altered behavior, and decreased growth and hatching success.
    • Boric acid is relatively nontoxic to bees.

    Signs of toxicity in humans.

    • Investigators evaluated cases of people who ate boric acid. No patients experienced severe toxicity, and the majority did not have symptoms. In patients experiencing symptoms, the most common complaints were vomiting, stomach pain, and diarrhea. Sluggishness, lightheadedness, and rashes were less common symptoms.
    • Two siblings, one 24 days old and the other 14 months, were inadvertently fed boric acid in their formula. Symptoms included irritability, diarrhea, and redness in the groin area. Neither child developed severe toxicity nor had symptoms 1 month after the incident.

Fipronil

What is fipronil?

  • Fipronil is a phenylpyrazole insecticide which was introduced for use in animal health, indoor pest control, and commercial turf in 1996.

What is fipronil used for?

  • Fipronil is frequently used for the control of fleas, ticks, cockroaches and ants.

How does fiprinol work?

  • Fipronil disrupts normal nerve function. Fipronil acts by blocking the GABA-gated chloride channels of neurons in the central nervous system. The GABA-receptor system is responsible for inhibition of normal neural activity (i.e. prevents excessive stimulation of the nerves). When the system's regular functions are blocked by fipronil, the result is neural excitation and the death of the insect.
  • Fipronil kills insects by contact and ingestion. The principal path of activity is dependent on the insect target. It appears to be effective against adult and larval stages.

How toxic is fipronil?

  • The technical product (96.5% fipronil) has a high order of toxicity with respect to ingestion and
    inhalation in the rat, but appears to be less toxic via skin absorption. Fipronil is more toxic via skin
    absorption in the rabbit than in the rat.
  • Fipronil may cause mild irritation to the eyes and slight skin irritation. It does not sensitize the skin.
  • Signs of toxicity in rats include reduced feed consumption, anuria (no urination), increased excitability, and seizures.
  • Affected organs may include the liver, thyroid, and kidney.

What effect does fipronil have on wildlife?

  • Fipronil is highly toxic to fish and aquatic invertebrates. Its tendency to bind to sediments and
    its low water solubility may reduce the potential hazard to aquatic wildlife.
  • Fipronil is toxic to bees and should not be applied to vegetation when bees are foraging.
  • Fipronil has been found to be highly toxic to upland game birds, but is practically non-toxic to waterfowl and other bird species.
  • One of the metabolites of fipronil has a higher toxicity to birds than the parent compound itself.
  • Fipronil is non-toxic to earthworms, soil microorganisms and aquatic plants.
  • Fipronil is moderately toxic to small mammals if ingested.

Signs of toxicity in humans.

  • Data not found.

Permethrin

What is permethrin?

  • Permethrin is a pyrethroid. It is a synthetic chemical similar to the natural insecticide pyrethrum which comes from the chrysanthemum plant, but it remains effective for longer periods of time.

How does permethrin work?

  • Pyrethroids work by quickly paralyzing the nervous system of insects.
  • Permethrin kills insects when it contacts them or when they eat it.
  • It also has repellent effects.
  • It is effective against all stages of insect growth, particularly larvae.

Which of our products contain permethrin?

How toxic is permethrin?

  • Rats fed high doses of permethrin exhibited tremors,salivation, hyperactivity, hyperexcitability,
    urination, defecation and incoordination.
  • In a study involving newborn and adult rats, the newborn rats were found to be more sensitive to
    permethrin than the adults. The enzymes that break down permethrin in the body are not completely developed in the newborn rats. The incomplete development of the liver enzymes made the newborn animals more sensitive to permethrin than mature animals.

What effect does permethrin have on wildlife?

  • Permethrin has been found to be highly toxic to fish in laboratory experiments.
  • Permethrin is highly toxic to bees in laboratory conditions. However, when used properly, permethrin has a strong repellent effect in the environment and should pose little risk to bees.
  • Permethrin is of low toxicity to birds.

Signs of toxicity in humans.

  • Permethrin has low to moderate toxicity to humans for short-term exposures.
  • Results of animal studies suggest that human newborns may be more sensitive to permethrin than
    adults.
  • Permethrin acts similarly to the insecticide pyrethrum (from the chrysanthemum plant).
  • Pyrethrum can cause skin or respiratory reactions in people with hayfever or in people who are sensitive to ragweed and pollen.
  • These reactions may include irritation or inflammation of the skin (contact dermatitis) or sneezing, nasal stuffiness, or asthmatic breathing. Although there is no clear evidence that pyrethroids (such as permethrin) cause allergic-type reactions, it is important to recognize this possibility.
  • Exposure to permethrin may occasionally produce numbing, tingling, and burning sensations of the
    skin. These sensations are reversible and usually go away within 12 hours.

Pyrethrins & Pyrethroids

What are pyrethrins?

  • Pyrethrins are insecticides that are derived from the extract of chrysanthemum flowers (pyrethrum).
  • The plant extract, called pyrethrum contains pyrethrin I and pyrethrin II collectively, called pyrethrins.

What are pyrethroids?

  • Pyrethroids are synthetic (human-made) forms of pyrethrins. There are two types that differ in chemical structure and symptoms of exposure.
  • Type I pyrethroids include allethrin, tetramethrin, resmethrin, d-phenothrin, bioresmethrin, and
    permethrin.
  • Some examples of type II pyrethroids are cypermethrin, cyfluthrin, deltamethrin, cyphenothrin,
    fenvalerate, and fluvalinate.
  • Both type I and II pyrethroids inhibit the nervous system of insects. This occurs at the sodium ion
    channels in the nerve cell membrane. Some type II pyrethroids also affect the action of a eurotransmitter called GABA.

What are pyrethrins and pyrethroids used for?

  • Pyrethrins are widely used for the control of various insect pests.

How do pyrethrins and pyrethroids work?

  • Nerve cell membranes have a specific electrical charge. Altering the amount of ions (charged atoms)
    passing through ion channels causes the membrane to depolarize which, in turn, causes a neurotransmitter to be released. Neurotransmitters help nerve cells communicate. Electrical messages sent between nerve cells allow them to generate a response, like a movement in an animal or insect.
  • Pyrethrins affect the nervous system of insects by causing multiple action potentials in the nerve cells by delaying the closing of an ion channel.
  • Pyrethrins and pyrethroids act as contact poisons, affecting the insect's nervous system.
  • Even though pyrethrins and pyrethroids are nerve poisons, they are not cholinesterase inhibitors like
    organophosphate or carbamate insecticides.
  • Pesticide products containing pyrethrins usually contain a synergist (such as piperonyl butoxide).
  • Synergists work by restricting an enzyme that insects use to detoxify the pyrethrins. A synergist allows the insecticide to be more effective.

Which of our products contain pyrethrins and pyrethroids?

How toxic are pyrethrins and pyrethroids?

  • Pyrethrins are one of the least poisonous insecticides to mammals.
  • Rats fed high doses (1,000 milligrams per kilogram of body weight or mg/kg) of pyrethrins showed liver damage.
  • Rats exposed to pyrethrins exhibited difficulty or rapid breathing, incoordination, sprawling of limbs,
    tremors, aggression, sensitivity to external stimuli, twitching, and exhaustion.

What effect does fipronil have on wildlife?

  • Pyrethrins are highly toxic to fish and tadpoles. They affect their skin touch receptors and balance organs.
  • Pyrethrins are toxic to beneficial insect (such as honeybees) and many aquatic invertebrates.
  • Pyrethrins are low in toxicity to humans, other mammals, and birds.

Signs of toxicity in humans.

  • Inhaling pyrethrins can cause coughing, wheezing, shortness of breath, runny or stuffy nose, chest pain, or difficulty breathing.
  • Skin contact can cause a rash, itching, or blisters

Deltamethrin

What is deltamethrin?

  • Deltamethrin is a pyrethroyd insecticide that kills insects on contact and through digestion. It is a synthetic insecticide based on natural pyrethrins.
  • Deltamethrin products are some of the most popular and widely used insecticides in the world.

What is deltamethrin used for?

  • Deltamethrin has a very broad spectrum of insect control and is effective against cockroaches, flies, fleas, beetles, bed bugs and a large number of other insects and bugs.

How does deltamethrin work?

  • Deltamethrin causes death due to irreversible damage to the nervous system. It rapidly paralyses the insect's nervous system resulting in a quick 'knockdown' of the insect.

Which of our products contain deltamethrin?

How toxic is deltamethrin?

  • Deltamethrin is highly toxic to insects.
  • Mammalian exposure to deltamethrin is classified as safe provided it is used in accordance with the product label.

What effect does deltamethrin have on wildlife?

  • As is common with all pyrethroids, deltamethrin has high toxicity to bees.
  • It is extremely toxic to aquatic insects and fish.

Signs of toxicity in humans.

  • Deltamethrin is a neurotoxin, it attacks the nervous system of insects and mammals.
  • Skin contact can lead to tingling or reddening of the skin local to the application. If taken in through the eyes or mouth, a common symptom is facial paraesthesia, which can feel like many different abnormal sensations, including burning, partial numbness, 'pins and needles', skin crawling, etc.
  • Recently, in South Africa, residues of deltamethrin were found in breast milk, together with DDT, in an area that used DDT treatment for malaria control, as well as pyrethroids in small-scale agriculture.
