How to Control and Eliminate Chinch Bugs

Chinch Bug Control


The frequent guest of our southern lawns, the chinch bugs, can cause extensive, unsightly damage to your lawns.  Known to attack St. Augustine, Zoysia, Bermuda and Centipede grasses.


Chinch bugs are one of the most invasive insects that will attack your lawn.

Chinch Bugs go through incomplete metamorphosis. The first few instars appear a reddish color. The adult chinch bug will be about ⅕ th of an inch, black with white wings that are folded over their backs.


Unfortunately, these little fellows can fly and will travel from lawn to lawn.  The injured lawn will turn yellow to brown in patches that have an irregular shape. Theses symptoms will be found near sidewalks or driveways or where the turf has direct sunlight all day.  You will not locate them in the shady or moist areas.


What is the threshold of control?


When you are trying to figure out when you should treat for chinch bugs, follow these rules:  Locate 20 to 25 Chinch bugs per square foot of turf, then a professional would recommend that you apply some type of insecticidal remedy.


How to do a sampling method:


Flotation Method:


  1. Take a coffee can, remove the top and the bottom


  1. Push into the soil where there might be suspected activity and give it a couple of twisting motions


  1. Use a knife and cut the soil around the outer rim of the coffee can.


  1. Fill with water for about 10 minutes and check for chinch bugs as they float the surface.

  2. If you find as many as 2 to 4, then now is the time to apply your insecticide.


Do not confuse the chinch bug with the big eye bug, they have big eyes and are predators of the chinch bugs.

3 easy Steps to Chinch Bug Control 


  1. Reclaim I/T, use 1 ounce per 1,000 sq ft. In a sufficient amount of water to ensure penetration of turf grass. This is best achieved by using a Hose End Sprayer. Be sure to treat the entire lawn.

  2. Remove excessive thatch and apply a Liquid Nitrogen fertilizer and top dress with light organic mulch.

 3. Adding some slow release nitrogen will help help keep your lawn less desirable to Mr. Chinch Bug and an annual application of a light dusting of the soil with compost.
