Getting Rid of Grub Worms
Q: When we were dethatching our lawn and pulling weeds from the beds we found lots of grub worms, what can we do to get rid of them and when?
A: The best time to kill grubs in Texas is from March to August. Look for a product containing IMIDACLOPRID, an insecticide that should not harm beneficial insects in the soil. Read the label carefully. The insecticide attaches to the roots of the grass and shuts down the grubs ability to feed. The ability to kill the grubs depends on how deep they are in the soil, how much it is watered in and the amount of clay in the soil. As with the any product it will not wipe out every single grub. In the average lawn there will be grubs at any time of the year, if you find 3 or more in a 12 inch by 12 inch area that it is considered an infestation and a serious threat to the lawn. Most lawn insecticides should not be used within 3 to 4 feet of vegetable crops.
