Here is what a Mo Dept of conservation agent responded in another forum
The question:
I have a question regarding Artificial Lights and hunting in Missouri. I have been advised both ways and wanted to get it straight from the state. I saw a thread that addressed lights but not landowners. I read at
http://mdc4.mdc.mo.gov/Documents/2116.pdf on page 15 “Artificial Lights may be used only to hunt bullfrogs and green frogs, or to hunt raccoons and other furbearing animals when treed with the aid of dogs. Using lights or any other night vision or thermal imagery equipment to search for, spot, illuminate, harass or disturb other wildlife is a violation of the Wildlife Code. This rule does not apply to landowners on their property.”
May I, as a landowner, on my property, not on a roadway, use an artificial light to shoot nuisance coyotes who have been eating my chickens?
The reply:
The answer to your question is No. Landowners may not use a light to hunt coyotes.
(B) Artificial Light. No person shall throw or cast the rays of a spotlight, headlight, or
other artificial light on any highway or roadway, whether public or private, or in any
field, woodland, or forest for the purpose of spotting, locating, or attempting to take or hunt any game animal, except raccoons or other furbearing animals when treed with the aid of dogs, while having in possession or control, either singly or as one (1) of a group of persons, any firearm, bow, or other implement whereby game could be killed.
The landowner exemption is for landowners checking on their property and livestock.
My opinion: You should contact your local agent and ask for permission to use a light on predators destroying livestock on your own land. I can tell you for certain that if you do get their blessing or offer to look the other way, that it will not apply to property you do not own.
