Today is April Fools Day but here’s no joke. Now’s the time to spray your outdoor clothes with permethrin to repel black-legged ticks that carry Lyme disease.

Black-legged ticks (Ixodes scapularis), sometimes called deer ticks, are tiny blood-sucking arachnids that transmit the parasite that causes Lyme disease from small rodents to us.

Lyme disease is debilitating and if not stopped early can ruin your life for a very long time. If you live in Pennsylvania you probably know someone who’s had Lyme disease, maybe even yourself. Pennsylvania has the most Lyme disease cases per year in the U.S. — 10,001 of them in 2018 according to this PennLive report.

The predictions for 2019 say Lyme disease will be even worse in Pennsylvania this year. Black-legged ticks need moisture to survive and the past year has been wet. There will be lots of ticks. Watch out!

So how do we avoid getting Lyme disease?

  • Stay away from places where black-legged ticks live,
  • Keep ticks off your skin,
  • Check your body daily for any ticks that got through those defenses.

Unfortunately most of us can’t stay away from tick habitat. It’s in our own backyards.

Black-legged nymphs live in moist leaf litter or at the edge of wooded areas. Many people catch Lyme disease while gardening. Have you been moving damp leaves lately?

Don’t fool yourself that you’re completely safe in city parks. A 2017 study of Pittsburgh’s regional parks — Highland, Schenley, Riverview and Frick — found infected ticks in all of them. Highland was the worst. Download the study here.

The best defense is to keep ticks off your skin.

  • Stay on-trail as much as possible. (Not possible when gardening!)
  • Wear light-colored clothing so you can see ticks if they get on your clothes.
  • Wear long pants and long sleeves. Before you step off trail, pull your socks over your pant bottoms.
  • To really keep ticks away spray your outdoor clothes — pants, shirts, socks, shoes, jacket, hat — with permethrin. READ AND FOLLOW LABEL DIRECTIONS. The repellent lasts through six washings. It works really well for me.

And as always, take a shower shortly after coming indoors and check your body for ticks every day. Read more about tick prevention and daily checks at these links.

Get ready for a bad tick year.

  1. You need possums in your yard.
    They can eat 5000 in a season. More if there are tons of ticks.

    Love your blog!

  2. I have come across a lot of possum related articles lately, ones pertaining to ticks. There is quite a dispute going on about possums and how many ticks they do or do not eat. Making matters worse most possum related articles often devolve into a referendum on possums, in general. We are pro possum! Guinea fowl also have a voracious appetite for ticks, a pack of guineas will decimate a tick population. https://www.tickproofrepellent.com/guinea-fowl-and-ticks/
