You DO need a hunting license... 100%
For varmints in TX? No.
"A hunting license is required of any person, regardless of age, who hunts any animal, bird, frog or turtle in this state (except furbearers, if the hunter possesses a trapper's license). No license is required for
nuisance fur-bearing animals, depredating hogs or coyotes (see below). Non-residents under 17 years of age may purchase and hunt with the Youth Hunting License (Type 169)."
"Landowners
or their agents may take nuisance fur-bearing animals in any number by any means at any time on that person's land without the need for a hunting or trapping license. However, fur-bearing animals or their pelts taken for these purposes may not be retained or possessed by anyone at any time except licensed trappers during the lawful open season and possession periods.
Nuisance fur-bearing animals may be captured and relocated if the person has received authorization from the department and the owner of the property where the release will occur. A monthly report is required and must be submitted to the department on number and kind of fur-bearers captured, location of release site, name and address of person authorized to release."

As the AGENT for a landowner, I am only restricted from taking FURS from said prairie dogs and coyotes without a license.
"Exceptions
A hunting license is not required to hunt the following:
Coyotes, if the coyotes are attacking, about to attack or have recently attacked livestock, domestic animals or fowl.
Depredating feral hogs, if a landowner (resident or non-resident) or landowner's agent or lessee is taking feral hogs causing depredation on the landowner's land.
Fur-bearing animals, if the hunter possesses a trapper's license
or if the fur-bearing animals are causing depredation."
If the landowner wants them gone, prairie dogs are "causing depridation".
Now with that being said, a bunch of the 'normal' game species that would usually have a season and limit, they get REAL particular about on a county by county basis. For instance don't get caught shooting at or in possession of a wild turkey in MANY counties in NTx, its strictly verboten.
