Mosquito larvae in water

There are some studies that suggest that coffee grounds can be used as a home remedy against Mosquito larvae in stagnant water (e.g. rain barrel and garden pond) and against Sciarid gnats in the Potting soil can be effective.

In 2006 the team discovered the Biologist Alessandra Laranja from the Institute of Biosciences, Letters and Exact Sciences (Ibilce) of the UNESP “Universidade Estadual Paulista” that 500 micrograms of caffeine per milliliter of water block the development of the larvae in the second phase of their life cycle and thus prevent them from reaching adulthood. The biologist argued that Altered caffeine esterase enzymes, which are responsible for basic physiological processes such as hormone metabolism and the reproduction of mosquitoes. Caffeine also reduces the lifespan of adult mosquitoes, especially female mosquitoes that carry the dengue, chikunguya, and zika viruses.

The biologist explained that it is not necessary to dilute the coffee grounds with water in order to use them. He can directly into flower pots, orchards and vegetable gardens, drains, sewers and generally in any container that is outdoors and can hold water (tires, bottles, cans, boxes, etc.). However, a solution of four tablespoons of coffee grounds and a glass of water makes this natural larvicide easier to use.

Against mosquitoes in the potting soil Cold coffee diluted with water in a ratio of 1: 1 is also effective. However, this should not be exaggerated. Sciarid gnats typically have a lifespan of 3 to 7 days.

You can also put the coffee solution in an atomizer and use it to fog the plants. Since the mosquito can breed even inside a bromeliad or in very thin layers of clean water, Laranja recommended spraying this natural insecticide on plants and any suspicious areas.

Coffee extracts were again used in 2012 to prevent larval development and to kill both Aedes aegypti and Aedes albopictus mosquito populations – both caffeinated and decaffeinated versions. A 2015 study also showed that mosquitoes can get through the darker color of coffee-treated water will keep eggs from laying. And if they do, the larvae die, as has already been proven.
