While metofluthrin is a moderately toxic pyrethroid insecticide, the packaging and presentation of the product, i.e. the polyethylene slow release matrix and the overall low toxicity, and risk of inhalation toxicity was considered to be low due to the formulation of the product.
Metofluthrin, like other pyrethroids, is neurotoxic in rats, rabbits, and dogs; both sexes were equally sensitive to metofluthrin. Clinical signs include tremor (all species), vomiting (dog only), and increased salivation (rats and dogs).
Metofluthrin reduces biting activity in Aedes aegypti through the confusion, knockdown, and subsequent kill of a mosquito. A geographical spread in dengue, chikungunya, and Zika viruses, increases intervention demands.
Conclusions: Meperfluthrin causes airway mucosal damage and hypersensitivity. Lung CT and lung tidal function measurements can be used to monitor changes in the condition. Presently, there is a lack of specific detoxification drugs for meperfluthrin poisoning.
Allethrin and metofluthrin are also toxic to some animals including birds, fish, bees and cats. Dill said that "though the potential for harm to humans is there, it's probably low," but he cautioned to use these devices in moderation and never indoors.
Our tests have shown that the amount of ingredient deposited on surfaces near the Thermacell device is below what even sophisticated scientific instruments can measure, which is less than one billionth of a gram on one cm2.
► High exposure may cause headache, nausea and vomiting, dizziness, fatigue, muscle weakness, irritability, seizures, and a loss of consciousness.
It is generally considered nonpoisonous, but it can cause breathing problems if you breathe in large amounts.
The short answer is 'yes'.
Also, the emission of formaldehyde from burning one coil can be as high as that released from burning 51 cigarettes. Furthermore, long-term exposure to mosquito coil smoke (MCS) might induce asthma and persistent wheeze in children.
The Thermacell LIV Smart Mosquito System repellent cartridges use metofluthrin (5.5%) as the repellent active ingredient.
N,N-diethyl-3-methylbenzamide (DEET) remains the standard by which all other repellents are judged.
A: Thermacell products are safe to use around people and pets as long as it is used as directed. Thermacell products are for outdoor use only.
Use Around Children
The science and data on our ingredients indicate that they should not be of concern, if used according to label instructions, for people or pets. Thermacell's extensive data is thoroughly reviewed by the US EPA and multiple other regulatory agencies around the world in the product approval process.
Metofluthrin is a pyrethroid used as an insect repellent. The vapors of metofluthrin are highly effective and capable of repelling up to 97% of mosquitoes in field tests.
Thermacell works. Period. Refills are prohibitively expensive. Basically a 5.5% Metofluthrin solution.
Most mosquitoes avoid direct sunlight, coming out at night to feed. This means you're far more likely to get bitten by those pesky bugs while you're asleep, but luckily there are a few things you can do to prevent them getting into your room in the first place.
To avoid overexposure, be sure to remove DEET product before going to bed (shower or use a wash cloth to remove from skin).
DEET is a widely used repellent that deters pests by making it harder for them to smell humans. Despite being effective, it has faced controversy over potential health and environmental impacts, including skin irritation and toxicity concerns. Some countries have even banned DEET due to these risks.
Many insecticides can cause poisoning after being swallowed, inhaled, or absorbed through the skin. Symptoms may include eye tearing, coughing, heart problems, and breathing difficulties. The diagnosis is based on symptoms, blood tests, and a description of events surrounding the poisoning.
Inhaling the contents may be harmful or fatal. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. If vapors are inhaled, remove person to fresh air. This product is toxic to fish and aquatic invertebrates.
Allethrin appears as a clear amber-colored viscous liquid. Insoluble and denser than water. Toxic by ingestion, inhalation, and skin absorption. A synthetic household insecticide that kills flies, mosquitoes, garden insects, etc.
Our products contain active ingredients that repel mosquitos and inactive ingredients that assist with their release into the air. Our fuel-powered repellent mats use allethrin as the repellent active ingredient.
