Tick bites surge in the U.S. as online conspiracies spread

tick bites – Rising temperatures are driving earlier tick season and more bites, even as online communities push unproven bioweapon and vaccine plots.

A dead moose can tell a larger story than most people expect: in Maine, winter ticks have been feeding so aggressively that shed-hunter Drew Maciel says he’s found animals dying in a way that points to a fast-changing climate.

Maciel. who collects antlers naturally shed by wildlife. posted images of a dead bull moose covered in clusters of ticks tucked into the animal’s crevices.. He described a shift he’s noticed this year—rather than the usual pattern of encountering healthy wildlife. he has kept turning up dead animals.. Researchers tracking moose calves in Maine have reported that up to 90% of calves have been bled to death by ticks in recent years. a grim toll that has added urgency to a problem in a state that prizes the largest deer species.

Scientists point to a warming pattern behind the tick pressure.. Temperatures in Maine have risen about 3 degrees Fahrenheit since 1985. and that change is linked to a winter tick “feeding frenzy.” But the physical reality on the ground is also colliding with a very different explanation spreading through social media: some viewers interpret the same trend as evidence of coordinated wrongdoing rather than ecology.

Online. tick encounters are increasingly wrapped in conspiracy theories. with claims that blame “human engineered biological warfare. ” or insist that influential figures such as Bill Gates are orchestrating outbreaks.. A comment on Maciel’s video attributed to a convicted far-right figure drew significant attention. while other posts suggested familiar names as the source of the problem.. The broader effect is not just misinformation; it is an alternative narrative that reframes climate-driven shifts as deliberate plots.

One viral thread. first appearing in 2023. claimed that pharmaceutical companies developing vaccines for Lyme disease were planting boxes of ticks on farms to increase demand.. A related conspiracy tied genetically modified cattle tick research—partly funded by the Bill and Melinda Gates Foundation—to rising red meat allergies in the U.S.. The problem is that the best-known red meat allergy. Alpha-gal syndrome. is linked to bites from Lone Star ticks. a different species than the cattle ticks discussed in that research program.

Even when the theories point to different ticks. different diseases. and different alleged culprits. they often function as interchangeable proof for a single overarching claim: that tick-driven increases are part of a nefarious human plan.. The scientific record. however. supports a different chain of causation—one centered on climate change and how it reshapes where and when ticks survive. quest for hosts. and bite.

The theories are “right about one thing,” ecologists say in effect, because tick pressure really is worsening.. The same ecological changes that help fuel Maine’s winter tick boom are also making tick encounters more common across much of the U.S.. Researchers note that ticks are showing up earlier in the year. expanding into new terrain. and biting people more often than they used to.

Richard Ostfeld. an ecologist at the Cary Institute of Ecosystem Studies. said warming is bringing ticks out earlier. including in states such as New York where it used to be safer around May.. “Now. not so much. ” he said. describing how shorter seasonal windows for tick exposure are giving way to longer periods of risk.

Federal health data points to the same direction.. The Centers for Disease Control and Prevention said tick season has started unusually early this year across most of the country.. In an alert published late last month. the agency reported that emergency room visits for tick bites in four of five tracked geographic regions are the highest they’ve been for this time of year since the CDC began monitoring tick-borne illness rates in 2017.

This year’s rise in bites does not appear to have a single driver identified by the CDC. but researchers say multiple natural mechanisms can stack.. Ample snow earlier in the year may have helped insulate adult ticks from winter cold. while an early spring bloom across much of the U.S.. could have brought hungry adults out of leaf litter sooner than usual.. Regardless of the specific timing details. the larger trend is consistent: rising average temperatures can both push ticks northward into areas that were once too cold and extend how long ticks remain active each year.

More bites also translate into more chances for infection, and the set of diseases doctors monitor continues to broaden.. Positive tests for Alpha-gal syndrome have increased 100-fold since 2013, and nearly half a million people in the U.S.. now carry an allergy to red meat.. Cases of anaplasmosis—carried by black-legged ticks and associated with hospitalization for roughly 30% of people who contract it—rose 16-fold between 2000 and 2017.. Babesiosis, a malaria-like illness also carried by black-legged ticks, has risen by roughly 10% per year since 2015.

Because the bacteria and parasites carried by ticks do not arrive neatly in separate categories. the clinical picture can become more complicated: it’s not uncommon for a single tick to carry two or more diseases.. That reality reflects an interwoven web of factors—land-use and wildlife changes that increase contact between people and ticks. invasive and expanding tick species that introduce new disease risks to new places. and improvements in testing and reporting that make tick-borne illnesses more visible.

For Ostfeld, the danger isn’t only biological; it’s communicative.. He worries that the complexity of the causes behind tick-borne disease increases. combined with the appeal of online conspiracies. may make it harder for people to grasp why backyards in certain regions are becoming riskier.. When simplified or sensational explanations crowd out the science. even moderately complex public health realities—such as when and where tick exposure is likely—can become harder to understand.

The misinformation ecosystem has also gained credibility. critics say. when prominent political and media figures amplify claims about the origins of tick-borne illnesses.. Robert F.. Kennedy Jr.. Secretary of Health and Human Services. has repeatedly stated in the course of his career that Lyme disease was created as a byproduct of vaccine research and was used as a military bioweapon. a claim that conflicts with genomic evidence indicating the bacteria causing Lyme existed in North America for at least 60. 000 years.

Those ideas have also been promoted in mainstream political media discussions. Tucker Carlson, a major Republican-aligned media figure, has hosted the writer Kris Newby on podcasts in recent years, where Newby discussed debunked assertions about the military origins of Lyme.

Lawmakers have pursued investigation as well, underscoring how widely the bioweapon framing has taken root.. A formal effort to investigate Lyme’s origins was introduced twice in the House of Representatives by Chris Smith. a Republican representative from New Jersey.. A provision in the National Defense Authorization Act for Fiscal Year 2026. signed by President Donald Trump last December. requires the Government Accountability Office to investigate whether the military used ticks as biological warfare agents in the mid-20th century.. Smith described the mandate as broad. saying the GAO would be empowered to “leave no stone unturned. ” with an emphasis on the claim that ticks were “weaponizing” efforts.

Yet outside the hearings and viral videos, the evidence for intentional wrongdoing looks thinner.. In the Midwest. where social media users have told millions they should expect boxes of ticks dumped on farms. reports of such activity remain hard to confirm.. Terry Hoerbert and her husband Bob own Little Brown Cow Dairy in Delavan, Illinois.. Terry said the approach to their farm is too short for someone to have dropped off packages without being seen.. She told MISRYOUM that she has not heard of other farms in the area receiving live ticks—adding that she was the first person to inform them of the story.

For families and farmers facing more tick encounters. the contrast between lived experience and online explanations may define what happens next.. As the CDC reports the early season and scientists track climate-driven shifts. the public health challenge is not only reducing exposure to ticks. but also ensuring that the reasons for changing risk are grounded in evidence rather than amplifying narratives that point away from the real drivers.
