We believe we have a tick problem so I thought I would try an Organic lawn insect killer (EcoSMART Lawn Insect Killer). The product manufacturer alleges that the product KILLS AND REPELS: Ants, Aphids, Caterpillars, ticks, and many other lawn and landscape insects. It also alleges that it kills on contact. The manufacturer states that the product is a octopamine blocker which insects have but not mammals or other animals. It blocks the octopamine and "results in a total breakdown of the insect’s central nervous system."
Keeping and open mind I thought I would try this natural products (as I have 2 dogs and two youngsters). After spraying the lawn I thought this may actually work. As a test sprayed a collection of ants, gnats, beetles, and various other winged and non winged insects that were on some vegetable matter. They continued to scurry around. After dousing them with this insect killer they just continued about their business. The repellent aspect did not appear to work. The product is natural so I figured that maybe "kills on contact" is not immediate and takes some time to affect the insects. I checked the insects at 5, 15, and 30 minutes - they were just laughing at me and not one of them appeared to have been repelled or killed by this product.
Maybe at a higher concentration this product works but I sprayed a 1 foot square area of bugs with enough spray for a 10x10 area of lawn. I am not holding my breath that this product killed any ticks in my lawn. A friend has had success with EcoSMART lawn weed and grass killer so some of their products may yield better results.
