Do Controlled Burns Kill Ticks? What One Study Found
Controlled burns may reduce host-seeking tick populations.
One Texas study found substantially fewer ticks after prescribed burns.
Prescribed fire works best as one part of integrated tick management.
Do controlled burns kill ticks? Research suggests that controlled or prescribed burns can reduce tick populations under certain conditions, but they are not a permanent solution.
In a study from eastern Texas, researchers found significantly fewer host-seeking ticks in areas with a history of prescribed burns compared with nearby unburned areas. Although encouraging, the authors emphasized that controlled burning should be viewed as one component of an integrated tick management strategy rather than a stand-alone method for preventing tick-borne diseases.
Prescribed burns may reduce tick numbers temporarily, but they work best when combined with other proven tick-prevention strategies.
Understanding both the benefits and limitations of prescribed fire can help landowners, wildlife managers, and public health officials make informed decisions about reducing tick exposure.
Do Controlled or Prescribed Burns Kill Ticks?
In the short term, prescribed burns appear capable of reducing the number of host-seeking ticks.
In their study, Hodo and colleagues evaluated tick populations in an East Texas forest with different burn histories.
“Controlled burns may affect tick populations, pathogen prevalence, and risk of pathogen exposure to humans and animals and therefore may be a useful tool in integrated tick management.”
The investigators found a marked difference in the density of host-seeking ticks between burned and unburned sites.
According to the study, unburned areas contained approximately 15 to 18 ticks per 1,000 m², whereas previously burned areas contained only 2 to 4 ticks per 1,000 m².
“We observed low questing tick density in areas with a history of controlled burns,” the authors reported.
Lower tick density may reduce the likelihood of human exposure to tick bites. However, this study did not evaluate whether prescribed burns reduced the incidence of Lyme disease or other tick-borne illnesses.
Which Ticks Were Found?
Researchers collected 112 ticks using drag sampling.
- Approximately two-thirds were Ixodes scapularis (blacklegged or deer ticks), the primary vector for Lyme disease.
- The remaining ticks were Amblyomma americanum (lone star ticks), which can transmit several other tick-borne pathogens.
The research team also recovered 106 ticks from the clothing of field workers, highlighting the occupational exposure faced by individuals conducting tick surveillance.
What Pathogens Were Detected?
The investigators did not detect Borrelia burgdorferi, the bacterium that causes Lyme disease, in any of the collected ticks.
However, they identified a relatively high prevalence of Rickettsia species along with a low prevalence of relapsing fever spirochetes.
These findings demonstrate that even when Lyme disease is absent in a particular region, other tick-borne pathogens may still pose important public health risks.
Do All Studies Agree?
Not entirely.
Hodo and colleagues reviewed previous research and found mixed results regarding the effectiveness of prescribed burning for long-term tick control.
Differences in climate, vegetation, wildlife hosts, burn frequency, season, and local ecology likely explain why studies have not produced identical results.
Most investigators agree that prescribed fire should be considered one tool within a broader integrated tick management program rather than a single long-term solution.
Clinical Perspective
Prescribed burns may reduce the number of host-seeking ticks immediately after a burn, but they do not eliminate ticks from an ecosystem.
As vegetation returns and wildlife hosts move back into burned areas, tick populations may gradually recover. For this reason, prescribed fire is generally viewed as one component of integrated tick management rather than a stand-alone strategy.
Even where prescribed burns reduce tick populations, people should continue using EPA-approved repellents, wearing permethrin-treated clothing, performing daily tick checks, and removing attached ticks promptly because no single intervention eliminates tick exposure.
Clinical Takeaway
Controlled burns can reduce tick populations in some environments, but they should not be relied upon as the sole method of tick control.
The East Texas study demonstrated substantially fewer questing ticks in previously burned areas, but long-term effectiveness depends on habitat, burn frequency, wildlife movement, and local ecological conditions.
Frequently Asked Questions
Do controlled burns kill ticks?
Yes. Prescribed burns can reduce the number of host-seeking ticks in some habitats, although they do not eliminate ticks completely.
Do prescribed burns reduce Lyme disease risk?
They may reduce exposure by lowering tick density, but burns alone have not been shown to reduce Lyme disease cases.
Can ticks survive controlled burns?
Some ticks are killed during a prescribed burn, but others survive in protected microhabitats or recolonize burned areas as vegetation and wildlife return.
Should homeowners use controlled burns to control ticks?
Controlled burns should only be performed by trained professionals under appropriate regulations. Homeowners should rely on proven tick-prevention measures such as repellents, protective clothing, landscaping, and daily tick checks.
What is the best way to reduce tick exposure?
An integrated approach—including personal protection, landscape management, wildlife management where appropriate, and public health education—provides the greatest reduction in tick exposure.

This is a temporary measure which would eliminate the ticks and reduce tick bites in the burnt area, until The mice they feed on and deer revisit for vegetation and residence. You are far better off to use the prescribed preventive steps and avoid high vegetation where tick quest for your blood. Blouse you pants into your socks, spray with Off Deep Woods, and don’t go into virgin woods if not necessary. Shower as soon as you get back to home base, and buddy inspect for ticks. Google Tick bites if you need more information, before you go out to tick habitats. Which may be your own back yard.
My parents bought a 40 acre property 50 years ago. Every night we all had to be checked for ticks before bed. They did controlled burns for about a 2 acre area surrounding our house for 3 years in a row. To this day, over 50 years later there is no longer a tick problem.
