:) What is the best way of getting rid of grubs ?
If best is way of less environmental impact there are nemotodes that are
supposed to be a long term option. I am not sure if BT var. BuiBui is
available on the market, but you might be able to research that.
If best is something working quickly, products containing Imidacloprid are
effective and will last a season. A side note would be are you sure you are
in need of any control. It will have to be a large population before damage
begins showing up, and I would say just a very small percentage of people I
come across, looking for grub control, actually need it.
There are several products/brands available that work well. The trick
is knowing when to apply the product. I'm reading conflicting stories
on BT effectiveness. I'll tolerate one grub per square foot, before
taking action. Letting it go, lead to mole problems (hills, tunnels,
Guess that would depend on what type of grub is involved. The action
threshold for crane fly larvae, for example, is more than 40 per square
And the type of grub also specifies the recommended treatment, assuming you
want to go organic and not use chemical insecticides.
In most parts of the country it is a little late in the season for grub
control. Best to wait until mid to late spring or early fall, when the grubs
are active and soil temperatures conducive to either nematodes or
Paenibaccillus popillea, aka milky spore.
