Issue: Grub Control and it’s Relation to Declining Bee Populations and Impact on Pollinators.
Prior to 2002 the way we handled grubs was by applying curative insect control treatments that would poison the grubs as they fed on the root system of your lawn.
However when products like Dylox and Diazinon were taken off the market, a new class of insecticides became the most inexpensive option. (By the way, “organophosphates” were made illegal because it was determined that they were impacting the central nervous system of children in a negative way.)
“Neonicotonioids” was the new class of chemicals that we began to use and their mode of action was systemic, meaning that the chemical was applied early enough that it becomes part of the tissue of the plant and when an insect consumes the plant (and the chemical) it kills them. With grubs they go through the molting process more quickly.
The issue here is that many beneficial insects also come in contact with the chemical. Think of a bee on a patch of clover or a dandelion. The working theory here is that pollinators ingest the chemical and in the case of bees, become confused and fail to return to their hives. Many beekeepers report complete losses in their hives in recent years.
Ask your lawn care service If they use a product called “Merit” which is the most common grub control nowadays. It’s likely that they do.
At Lawnmark we refuse to use neonicotinioids and offer two types of grub control. The first is a product called Acelepryn, which still acts as a systemic preventative but is so safe it carries no label warnings whatsoever and does not affect pollinators.
The second is a biological control that includes a specific bacteria that is toxic to grubs. (Chromobacterium). This option is completely organic.
