Marathon (imidacloprid) used on ornamental plants kills bees

Marathon is a formulation of the neonic insecticide, imidacloprid, that’s commonly used on ornamental plants in nurseries, garden centers, and homes across the US. A 2021 University of California paper shows that the application of Marathon, even at 30% of the recommended dose, killed 90% of leafcutter bees.

Risk-benefit analysis of Bayer’s imidacloprid

Bayer’s imidacloprid is one of the most widely used insecticides and belongs to a group of pesticides known as neonics (or neonicitinoids), which target insects’ nervous systems. Following extensive research I present a risk/benefit analysis for imidacloprid. Neonics are often used by default, for example as seed coatings, and yet offer no benefit in many cases. The risks, on the other hand, are sobering and demand immediate action.

Seresto flea collar & imidacloprid

Earlier in March, USA Today reported that bestselling Seresto flea collars have been linked to 1700 pet deaths in the US – and that’s just going by the number reported to the Environmental Protection Agency (EPA); the actual number is expected to be higher. The story originated from Johnathan Hettinger at the Midwest Center for … Continue reading Seresto flea collar & imidacloprid

The EU bans neonics. What will the US do?

the EU has voted to ban neonics (neonicotinoids) in Europe, putting a more permanent stamp on the temporary ban that had been in place since 2013. Will the US follow suit?

The subtle effects of neonics on bees

The subtle effects of neonics on bees is the topic of this third post looking at the connection between the use of neonics (neonicotinoids) in agriculture and bee health. I'm a research scientist and have no agenda here, other than uncovering the truth. In parts one and two I’ve focused on the toxicity of the … Continue reading The subtle effects of neonics on bees

Examination of evidence that neonicotinoids are safe for bees

In this post I will examine a case often cited by Bayer & Co. as evidence that neonicotinoids are safe for bees. This is part two of an impartial investigation into whether neonicotinoids (neoincs) are harmful to honey bees. I have nothing to gain from a position on either side of this debate and have … Continue reading Examination of evidence that neonicotinoids are safe for bees

How do neonicotinoids affect bees?
