Permethrin and pyrethrum insecticides are quite similar. They both sound similar and have similar qualities. They both kill unwanted insects and mosquitos. But, on closer examination, permethrin and pyrethrum are very different in structure, chemical composition, and even in their manner of acquisition. So, let’s explore the topic of permethrin versus pyrethrum to see what makes them so different from each other and to find out which one is better for whatever your intended use may be.
Permethrin is a chemical used in insecticides to kill mosquitoes and other insects. It is also used in medications that treat scabies and lice. In animals, it is used to eradicate lice and other parasites which may be in their fur or, even worse, living inside of them.
Permethrin insecticides are available in creams, lotions, and sprays. Even though this pesticide can be found in medications and is meant to be applied to the skin, it is a chemical and, therefore, can cause rashes, hypersensitivity, and skin irritation. Even though it might cause some skin irritation, it is not dangerous or unsafe for adults or children over two months of age. Permethrin insecticides should be used only when necessary and in the correct amounts, as is true for all medications. If permethrin is used according to the safety instructions that come with the product, any side effects will not be likely to appear.
Permethrin is also utilized in agriculture where it is used to fight the pests that may infest various different crops. But, as it is a wide spectrum insecticide that is intended to kill various kinds of pests, it also kills beneficial insects such as honeybees. It can also be harmful to aquatic life. Permethrin is used to fight pests and ticks which may infect other animals by being applied to the rodent populations which may house these insects. In addition, permethrin is used in tropical areas as a mosquito prevention measure to suppress deadly mosquito-borne illnesses such as malaria. By lining our bedding and clothing with this chemical, we can repel mosquitos and other insects that transmit different illnesses and infections. Even though permethrin is widely used worldwide for many different purposes, its main use is to combat pests and insects which may harm crops, such as cotton.
Pyrethrum is a natural pesticide found within a genus of flowers commonly called chrysanthemums. As it is naturally accessible, pyrethrum insecticide has been used as a pesticide for centuries. Moreover, because pyrethrum is a natural plant extract, pyrethrum insecticide is non-synthetic and also can be used on certified organic farms.
Chrysanthemum flowers are dried and crushed so that the active components, called pyrethrum, can be extracted and the pesticide acquired. Nowadays, pyrethrum is combined with other chemicals for greater effectiveness and can be found in many household pest control products. Even though pyrethrum is natural, pyrethrum insecticides are still dangerous for many mammals. Therefore, pyrethrum should be handled with the same amount of caution as synthetic pesticides because its toxic effects are quite similar to those of synthetic pesticides.
People who suffer an over-exposure to pyrethrum can experience side effects such as itchy or red skin, a runny nose, and even asthma symptoms. People who are sensitive and have allergies should be extra careful around chrysanthemums and pesticides manufactured from them, as they can cause health issues.
The differences between permethrin and pyrethrum
Permethrin and pyrethroid insecticides are a modified form of pyrethrum. Pyrethrum is the raw, natural form of this insecticide while permethrin and pyrethroids were created to substitute this strong natural insecticide and to be more stable. Permethrin and pyrethroids can still be deadly to bees, even in very small amounts. Therefore, it is recommended that you use them at night or as far from bees as possible.
The main difference between these two insecticides is that permethrin is a synthetic chemical made in laboratories while pyrethrum is a completely natural substance acquired from chrysanthemums.
The effects of both pesticides are quite similar, but, as permethrin is synthetic, it is more stable and effective when exposed to sunlight. For this reason, synthetic permethrin is used in agriculture more often than pyrethrum to protect crops from unwanted insects. Farmers need more stable pesticides which can withstand exposure to sunlight on those sunny, hot summer days.
In comparison with permethrin, pyrethrum is more environmentally friendly and safer, as it is a natural product. For small household needs, opting for pyrethrum will be better for your health and for the health of your pets.
Even though permethrin has relatively low toxicity, it can be extremely harmful to cats and some other mammals.
Altogether, the main difference between permethrin and pyrethrum is the way they are produced. One comes from flowers and is more eco- and human-friendly. The other is synthetically manufactured in laboratories and, therefore, is much stronger and with better, longer lasting results. Permethrin is more appropriate for large farms and crops, while pyrethrum is more appropriate for your household needs.
