L.T.M. Killer-EC

Indications

Cypermethrin is an insecticide. Emulsifiable concentrate (EC) products containing it are diluted with water and used on livestock and in animal housing to control external parasites such as ticks, lice, mites and flies, and in some cases on crops and buildings to control insect pests. Veterinary products of this type are for use on animals and premises, not for use on people.

How It Works

Cypermethrin is a synthetic pyrethroid, a man-made version of natural insecticides found in chrysanthemum flowers. It keeps the sodium channels in insect nerves open, causing over-excitement, paralysis and death of the parasite. Mammals break it down much faster than insects, which is why it is relatively safe for animals when used correctly, but it is highly toxic to fish, bees and cats.

Dosage and Administration

Dilute and apply exactly as directed on the label or by a veterinarian, as a spray, dip or pour-on depending on the product. The dilution, amount per animal and repeat interval depend on the species and the parasite. Wear protective gloves and clothing when mixing and applying. Do not apply to wounds, and do not use on cats.

Interactions

• Do not use together with other insecticides, especially organophosphates, unless directed, as toxicity can increase.
• Piperonyl Butoxide, found in some combination products, increases its strength.

Contraindications

• Cats, which are very sensitive to pyrethroids and can be poisoned.
• Very young, sick, weak or stressed animals, unless a veterinarian advises.
• Not for use on humans.

Side Effects

In animals, side effects are uncommon when used correctly, but may include skin irritation, itching, restlessness or salivation. In people handling the product, skin contact can cause a temporary tingling, burning or numb feeling (paraesthesia), especially on the face. Breathing in spray mist can irritate the nose and throat.

Get urgent medical help if a person swallows the product, has a seizure, muscle twitching, severe dizziness or breathing difficulty after exposure, and take the label with you. Contact a veterinarian urgently if an animal (especially a cat) shows tremors, drooling, seizures or collapse.

Pregnancy and Lactation

For animals, follow the label for use in pregnant or lactating animals and observe the milk withdrawal period. Pregnant or breastfeeding women should avoid handling concentrated insecticides where possible and must wear gloves and protective clothing if they do.

Precautions and Warnings

• Wear gloves, long sleeves and a face mask; do not eat, drink or smoke while handling; wash skin and clothes afterwards.
• Observe the withdrawal period for meat and milk stated on the label.
• Highly toxic to fish and bees: do not contaminate ponds, rivers or water sources, and do not spray on flowering plants.
• Keep cats away from treated animals until they are dry.
• Never store in food or drink containers; dispose of empty containers safely.

Overdose

In animals, overdose can cause tremors, drooling, unsteadiness and seizures. In people, swallowing it can cause nausea, vomiting, stomach pain, dizziness, muscle twitching and seizures; the solvent in EC products can also harm the lungs if vomited and breathed in. Do not induce vomiting; get emergency medical help. Treatment is supportive.

Therapeutic Class

Synthetic pyrethroid insecticide and ectoparasiticide (veterinary and agricultural use).

Storage

Store below 30°C in a cool, dry, well-ventilated place away from light, heat and flames, in the original closed container, away from food and animal feed, and out of the reach of children and animals.
