Best Grub Killer Buying guide
With many grub killers on the market, it can be hard knowing which is the right one. Here are a few things to consider choosing grub treatment:
Types of Grub Killers
You can find 2 types available such as granular or liquid. Granules are the most common and simply spread over an affected area using a spreader.
The best grub killers won’t clump, neither will they be a fine powder, thus allowing even distribution.
You then water them in to activate the insecticides in the granules. Liquid grub killer is often a concentrate you dilute before application or ready to use grub sprays.
Spraying grub worm killer liquid is easy yet not as precise as granules for even coverage.
Organic or Chemical
Many white grub killers use chemical insecticides as active ingredients. Because of this, they are more effective. Japanese Beetles, for example, are controlled by milky spore, yet nothing much else can naturally control them.
You can find some chemicals that can kill beneficial organisms, like earthworms and bees.
Also, some are toxic, and you need to make sure not to use them near waterways in case of damage, and to let the treated areas dry before any family members or pets use the lawn.
You can see why there aren’t too many organic grub control products aside from milky spore. (Find Plants that Repel Fleas Safe for Pets)
Killer vs Prevention
Some insecticides kill all insects as soon as they make contact, they only often have short term effects. Other pesticides possess residual action which delivers longer protection over the treated areas. The best grub killers often have both abilities.
When checking all the information for these reviews, it was clear that the Ortho BugClear Lawn Insect Killer – Kills Ants, Ticks, Sod Webworms, Fleas and Spiders in Your Yard, Fast-Acting, Kills by Contact Above and Below the Ground would be the overall recommendation.
