Grub Worms

Anonymous added on September 11, 2013 | Answered

I am beginning to get all of these grub worms out of my swimming pool. I do not see them in the pool area, but when I get up, I have them all in the bottom of my pool. I have had my pool for 10 years and never had this problem before. I have not seen any in the yard. I have now developed a leak in my pool, though cannot find any holes in the liner. Is it possible that these grub worms can eat through the lining of my pool?

''Question: I have small pin holes in my swim pool liner what would cause this and is there anything I can spray around pool to prevent this?

Action Pest Control's Answer: I often see holes in pool liners that are caused by the larva stage of various types of beetles. Japanese beetles larva known grub worms often chew through pool liners. It sounds to me though you may be dealing with Pavement ants. They would create the pin size holes you described. They too will nest under pool liners because of the sand used at the bottom of the pool. The adults can chew plastic and rubber. The exterior perimeter around the pool needs to be treated with an approved pesticide. The treatment should be repeated monthly. I would make this a routine treatment for the pool area to prevent future colonies of insects from damaging the liner. '', is from this link:
