FORT COLLINS, Colorado (AP) — Tick season is starting across the U.S., and experts are warning the bloodsuckers may be as plentiful as ever.
Another mild winter and other favorable factors likely means the 2024 tick population will be equal to last year or larger, some researchers say.

“It’s very bad and has only been getting worse," said Susanna Visser of the Centers for Disease Control and Prevention.
An increasing variety of ticks are pushing into new geographical areas, bringing unusual diseases. Exotic southern species like the Gulf Coast tick and the lone star tick are being detected in New York and other northern states, for example.
But the tick that experts warn of the most is a common blacklegged tick, which is found mainly in forests and spreads Lyme disease. Infection rates begin to peak in May, and U.S. health officials estimate nearly half a million Lyme disease infections happen annually.
Here's a look at what's expected this year and how you can protect yourself.
Ticks are small, eight-legged bloodsucking parasites — arachnids, not insects — that feed on animals and sometimes people. Some ticks are infected with germs that can cause illness, and they spread those germs when they bite.
There is no widely accepted estimate of how many ticks there are from one year to the next, but there is a scientific consensus that they are an increasingly common health hazard in large portions of the United States.
Blacklegged ticks — also known as deer ticks, since they feed on deer — are among the most common ticks in the eastern half of the U.S. They were plentiful centuries ago, then diminished when forests were cut down and deer were hunted, and rebounded alongside deer and wooded suburbs. The ticks have spread out from pockets in New England and the Midwest over a wider range, into the South and the Great Plains.
Tick populations cycle through the year and their numbers depend on a few factors. They like warm, humid weather, and more can be seen after a mild winter. The more deer and mice available to feed matters, too.
Overall, the blacklegged tick population has been expanding for at least four decades, researchers say.
“This is an epidemic in slow motion,” said Rebecca Eisen, a CDC research biologist and tick expert.
Weather can play a role in the severity of a tick season.
Very cold, dry winters can whittle down tick populations, but recent winters have been mild — a trend some attribute to climate change.
As Scott Williams, a tick researcher at the Connecticut Agricultural Experiment Station, said: "Winters are no longer limiting the tick population.”
Ticks can withstand the heat but tend to almost hibernate when it's a dry summer. That happened in Maine in 2020 through 2022, said Chuck Lubelczyk, a vector ecologist at the MaineHealth Institute for Research.
But last year was a very wet year, and tick activity multiplied in Maine — the state with the highest incidence of Lyme disease in the country. Weather service predictions call for higher temperatures and precipitation, so “on paper, at least, it could be a very good year for the ticks,” Lubelczyk said.
In Wisconsin, adult ticks were out longer than usual due to a mild winter. The tick nymphs are starting to emerge, and a wet spring is setting the stage for the possibility that the population will be robust, said Xia Lee, an entomologist at the Wisconsin Department of Health Services.
Ditto New York.
“It will be as bad as last year, or worse,” said Saravanan Thangamani, who studies ticks and tickborne diseases at SUNY Upstate Medical University in Syracuse.
Not all ticks are infected with disease-causing germs — about 20% to 30% of the blacklegged tick nymphs that emerge in the Northeast and Midwest this spring and into summer will be carrying the bacteria that causes Lyme disease, experts estimate.
Lyme disease symptoms tend to start between three and 30 days after a bite occurs and can include fever, headache, fatigue and a bull's-eye-like rash. If you get bitten and develop symptoms, see a doctor to get treated with antibiotics.
Experts say the best thing to do is take steps to avoid a tick bite in the first place.
If you go outdoors, make noted of wooded areas and where grassy properties start bleeding into wooded areas. Ticks tend to perch on ankle-level vegetation with their upper legs outstretched, waiting to latch on to an unsuspecting dog or human.
Try to walk in the middle of paths, wear light-colored and permethrin-treated clothing and use Environmental Protection Agency (EPA)-registered insect repellents.
When you come inside, check for ticks. They can be found anywhere on the human body, but common spots include around the waist, behind the knees, between fingers and toes, on underarms, in the belly button and around the neck or hairline.
They are harder to see when they are young, so look carefully and immediately pull them off with tweezers.
The CDC does not recommend sending individual ticks to testing services for analysis, because a person might get more than one tick bite and the results from the tested tick may not be sufficient information.

NEW YORK (AP) — Aryna Sabalenka left the U.S. Open in tears 12 months ago as the runner-up. She exited in the semifinals each of the two years before that. This time, Sabalenka was in a joking mood after winning her first championship at Flushing Meadows and the third Grand Slam title of her career.
Sabalenka, the No. 2 seed, got past No. 6 Jessica Pegula 7-5, 7-5 in a rollicking final under a closed retractable roof at Arthur Ashe Stadium on Saturday, adding this triumph to the two she earned at the Australian Open each of the past two seasons, also on hard courts.
“So many times, I thought I was so close to get a U.S. Open title. It’s been a dream of mine. Finally, I got this beautiful trophy. It means a lot,” said Sabalenka, a 26-year-old from Belarus, who is on a 12-match winning streak.
“I remember," she said, "all those tough losses in the past here.”
That includes in the semifinals in both 2021, against Leylah Fernandez, and 2022, against No. 1 Iga Swiatek.
Most poignant, of course, was last year, when Sabalenka was rattled by the Ashe crowd, blew a set advantage and was defeated by Coco Gauff. Like Gauff, Pegula is an American, but the spectators were far more generous toward Sabalenka on Saturday, applauding her best efforts and even obliging when she waved her arms to ask for extra noise.
Afterward, Sabalenka thanked the fans for cheering for her — which probably (wink, wink) was unrelated to her kidding offer of “Drinks on me” after an earlier victory.
Pegula, a native New Yorker whose parents own the NFL’s Buffalo Bills and NHL’s Buffalo Sabres, was participating in a major final for the first time at age 30. She’s won 15 of her past 17 matches over the past month; both losses came against Sabalenka.
“I know how tough it is to lose in the final, but you’re showing some amazing tennis, and I’m more than sure that one day, you’re going to get one,” Sabalenka told Pegula during the on-court ceremony, then paused and added with a chuckle: “I mean, not (just) one. Maybe more. But let’s start from one Grand Slam.”
To Pegula's credit, she did not fold after Sabalenka reeled off five consecutive games to grab the opening set and move ahead 3-0 in the second. In the next game, Pegula dropped a point and showed her frustration by whacking a ball off the video wall behind the baseline, dislodging a little square panel.
Maybe that released some tension, because suddenly Pegula asserted herself, using her own five-game run to go up 5-3. But when she served at 5-4 with a chance to force a third set, Pegula let Sabalenka level the second with a break.
“Was able to find some good tennis, just wasn’t quite able to sustain it,” Pegula said. “She played some big tennis in big moments.”
Indeed, that began a three-game surge for Sabalenka, who soon was collapsing to the court, dropping her racket and covering her face with both arms.
“Everyone is like, ‘Congrats! Amazing tournament!’” Pegula said. “I’m like, ‘Eh, whatever.’”
Sabalenka is as demonstrative as anyone, her body language usually a spot-on barometer of whether things are going well — or not — for her. But as she sputtered at the start Saturday, it was tough to read what she was thinking against Pegula, who eliminated Swiatek in the quarterfinals.
Even while down an early break and being a point from trailing 3-1, Sabalenka reacted to mistakes by calmly turning her back and taking deep breathing as star athletes from other sports such as Stephen Curry, Lewis Hamilton and Noah Lyles looked on from the stands.
Once Sabalenka got going, once her booming strokes — her forehands were the fastest of the past two weeks, speedier than any woman’s or man’s — were calibrated just so, it became apparent the outcome would be determined by what she did.
By the close, the statistics made that obvious: Sabalenka finished with far more winners than Pegula, 40-17, and also more unforced errors, 34-22. Sabalenka controlled most exchanges, with Pegula mainly stuck responding as best she could.
“She’s super powerful. Goes for her shots. She’s definitely not going to give you anything,” Pegula said. “I was happy I was able to fight back and give myself a chance, but in the end it wasn’t enough.”
There was one moment of clear anger from Sabalenka. It came at 5-all in the first set, when she double-faulted to face a break point, then leaned forward and cracked her racket against the court four times while holding the handle with both fists.
Seemed to work. She saved that break point, wound up taking that game, then broke Pegula to own the opening set.
A year ago, Sabalenka blew that lead against Gauff. The year before, Sabalenka blew that lead against Swiatek.
Didn't let it happen again.
“In that second set, honestly, I was just praying there,” said Sabalenka, who collected a $3.6 million winner's check. “I was literally standing there and praying.”
