I noticed a lawn grub this morning crawling in a dead patch on my lawn. I Applied as directed, watered in and 10 minutes later I came back to grubs calling on the surface everywhere

My couch lawn was quite spongy causing mower to bottom out creating browned spots. Did a hard scalp a few months ago and it recovered well but why is the lawn so spongy again? Well I found my answer after mowing last Friday afternoon 2 black beetles were spotted. This product doesn't specifically mention it targets Black Beetle or African but I can confirm it does with amazing resuts. Applied using my Scotts spreader then watered in. Within the hour I was truly shocked with the number of bettle coming to surface. The next morning it rained and this activated the product and more surfaced and died.

I bought and applied as per the packet recommendations. Popped the sprinklers on and came back to find the army worms and grubs that were infesting my lawn writhing on the surface, in significant numbers, within 30mins. Just like the picture from the previous reviewer. Great product, works fast on lawn grub/caterpillar pests.
Great products...works great on the lawn, now my problem is how do I get rid of some of the grubs that have gone into my garden?
Laid it down just before a rain shower and have 10+ birds afterwards picking all the law grubs up. Best to use the suggested applicator and follow the instructions
used it before
