I use minimal insecticides mainly because I’ve always had dogs and Murph is like a 4-legged mop because his legs are so short. I also don’t want to harm the good insects like bees, nor do I want to harm the birds. I prefer to let Nature take its course. Like the Assassin bug I found a couple years ago, I learned it killed the bad bugs, even though it was really ugly.
Over the weekend I spotted another highly desirable bug, a Praying Mantis. They’re fun to watch as they do their jerky movement and turn their strange head. Eventually it “walked” down to the green plant below where it became nearly invisible with its color match. If you check articles on Google, you’ll find that these insects are killing machines, attacking much larger critters like frogs! Amazing!
Also this past weekend I began cleaning up the brown spots I had in the yard. I thought they were due to the extreme dry weather we had. But as I began to use my thatching rake, I pulled up the sod … a sure sign of grubs. I was finding a grub for every 2 square inches. THAT’S A LOT!
I found this invasion over large parts of my back lawn. Given the time of year, I checked online for a specific insecticide that would kill them NOW. Many grub controls are preventative and must be put on in late spring. I found an article from Michigan State University that there are only 2 active ingredients that kill now. One of those took 3-4 weeks to work. The other kills in 24-hours. So I made a trip to Home Depot to buy the Bayer granules.
I tested the insecticide on one of the large damaged areas, soaked it with plenty of water, then watched the grubs squirm and try to bury themselves further down into the dirt. If it didn’t work, I wasn’t going to put it over other areas because of Murph. I checked the next day and the grubs were dead. I’ve since covered the area with topsoil to keep Murph from coming in contact with the granules. (The hose was circled around the spot to keep Murph off – he hates the hose!)
I’ll be repeating this process over all the other large areas where I spotted the nasty grubs. If there were just a few grubs, I wouldn’t bother with this, but if I don’t control them to some degree I’ll just have a bunch of June bugs next year with a repeat of the damaged lawn.
