Grubs are still a problem here right now with temperatures in the low to mid 80's and intermittent showers.

FYI, my pest control guy says Imidacloprid is definitly more beneficial before the eggs go to larva, Arena, Dylox or Bifenthrin after. He likes the Dylox because of cost, contact kill and residual, I suppose mostly cost.

Different strokes for different folks eh?

I believe you are in the grub capital of FL with your canal front properties correct?

The Weather has not been the normal Traditional Pattern this year. I Posted during a small Cold Front that wasn't long enough to cool off the ground temperature.

Grubs come to the surface to feed starting about July and normally go deep to over winter by Late Oct to early Nov.


The Sugar Cane Grubs in my area have become resistant to Imidacloprid. Bayer stopped listing them on the Merit Label 5 or 6 Years ago. Because of alkaline soil in my area Dylox is not real effective either. That leaves Liquid Sevin and Arena. Cost wise arena is out of the Ball park at first glance. But take in account it lasts season long and the cost of labor and it starts to balance out. Add in it is the only really effective product for my area and I am forced to use it.

i had very bad grub problems over the last few years. i used arena this year and had zero chinch bug problem or grub problems.. i think the problem i was having was not from the may/june bettle but from the sugar cane grub and that would explain why merit didnt work for me the last few yrs. i will use arena next year also b/c it worked so well this year...

like ric said it cost more but when you take into all of the other stuff into account its hard to beat...the cost of labor to lay new sod which i had to do the last 2 years..i only treat my own acre of turf....

How are products like Arena marked or tagged so you can tell if you can buy it if you are not licensed?

It's probably illegal to use these products on other than your own property unless you are licensed, check Texas (and your local) licensing requirements. Best to buy stuff at HD for your own yard or call a pest control operator.

So you imply that there is a list generated by the state to tell you what you need liscense for? And the HD chemicals are not getting the grubs any longer.

They sell Arena now at Home Depot!!! If you seriously are doing your own property and it is small under 5k - it is almost better for you to purchase your Arena there as opposed to Lesco at least as it is cheaper or roughly the same cost and you are not forced to buy the larger commercial bag that is at Lesco.

Ok Ric you need to talk more slowly I don't understand. How does a John Deere saleman know which chemicals require licenses? I am not in the spraying business but my yard is being eaten up by grubs. So I pop in over here to get some clue about what to use and walla here is the thread.

The state sets the requirements for chemical applications to turf grasses and ornamentals. For example; in Florida I have a limited application license that allows me to apply certain chemicals to the ornamentals and planting beds as well as fertilizer to turf grass.

There are limitations, I must apply pest control agents to the ornamentals by mechanical means, such as a back pack sprayer, I may not apply any pest control agent to the turf grass & that includes a "weed and feed" product. Check with your local extension what your requirements are, if any.

The label tells you whether or not it's restricted use. Commercial quantity is usually too much for an economical home owner application. Unless you got a bunch of acres, there'll be a bunch of dangerous chemicals in your storage facility for a long time.

Also, John Deere (LESCO) is way overpriced (my opinion). Like Michael said, you can get Arena at Home Depot, just saying.
