I won't be able to help you with an insecticide, but I do have some questions to confirm you're seeing chinch bugs. Chinch bugs are a HOT weather pest, so where do you live? Usually they appear near a hot sidewalk in the full sun all day. Is that what you're seeing? Have you swept the grass and seen the bugs?

There are YouTube videos about how to find and recognize chinch bugs. I believe they will suggest some insecticides, but I think you might be seeing something else.

Ortho Bug B Gon Max claims to kill 100+ insects including chinch bugs.

I live in southwest GA, about 25 miles North of Tallahassee FL. I have an area of grass that is not doing as well as the rest. I put soapy water on the area and a few chinch bugs came up. I will check out some you tube videos.

Can you take a picture (cloudy day or in the shade) and post it here? Take it from standing height and show any nearby pavement.

Do you know if anything might be buried in that spot? Tree stump? Rocks?

How high/low are you mowing?

What is your watering regimen (how often and for how long)?

If you look close up, do you see any green grass with yellow areas or tan spots with dark brown rings? If so then take a pic from about 3 inches away and post that.

Dchall, I will take some pictures and post. I am unaware of anything buried there but definitely no stumps or rocks. Funny you should mention that. During a recent home addition, my plumber found a chunk of concrete buried in the back yard (different area) from when the house was built in 1992.

I am mowing at the mowers highest setting. My watering regimen is by the book, one inch deep and infrequent.

I sent a soil sample to LL last week so the results should be in later this week.

Really glad to see someone is paying attention!!

Construction trash can be a hidden problem, so that's why I asked. I used to work for the guy who buried it, so I know it's a problem. Concrete can get hot and dry out the soil faster than adjacent soil. Tree stumps are buried wood, which can rob nitrogen from the soil. You don't want either one.

Just curious, how many chinch bugs per square foot is a problem?

Here are a few pictures.

Here is a picture of one of the little buggers!
