Some Felt More Was Needed Than Directions Stated

There were some comments stating that more is needed than what the directions stated.  Here is one of those comments, "Needs be applied about three times (as much as) the directions claimed area coverage in the South's summer. Perhaps spreading it considerably heavier would keep this from being necessary."

Works Well on Grub Worms

There were a lot of differences of opinions on what bugs this insect killer actually works on.  It does seem to work well on grub worms.  Here is one of the comments on grub worms, "Worked well at eliminating the pesky grub worms that brings the moles during the winter.
 I'm very satisfied with the product, and will use it again in the spring."

Spectracide Triazicide Insect Killer for Lawns Conclusion

The Spectracide Triazicide Insect Killer for Lawns had mixed reviews for which insects it kills and which it doesn't.  It does seem to work very well on grub worms.  It will be important to water it down after applying.  The product is made to cover 25,000 square feet though some customers said that it didn't cover that much ground for the amount of product that was needed.   How well this product actually works is still up for debate.  It didn't have as conclusive of reviews as did Terro T300 Liquid Ant Bait.  However, Terro was just for ants and this is supposed to kill over 100 different types of insects.
