When most people think about tick bites, they picture a hike deep in the woods. But here’s the surprising truth: most tick bites — and most Lyme disease cases — actually happen close to home, right in ordinary backyards.
Wait, What Is Lyme Disease?
Lyme disease is a bacterial infection spread to people through the bite of an infected tick — specifically the blacklegged tick (also called the deer tick). It can cause fever, fatigue, joint pain, and, if untreated, more serious long-term health problems. It’s more common than many people realize: the CDC estimates nearly 500,000 new cases happen in the U.S. every year, costing an estimated $1 billion annually to treat.
The Surprising Culprit: Mice, Not Deer
Most people blame deer for spreading ticks, since ticks are often called “deer ticks.” But deer aren’t actually where ticks pick up the Lyme disease bacteria in the first place. That happens earlier, when ticks are still babies (called larvae).
White-footed mice are the main animal that infects ticks with Lyme disease. When young ticks take their very first blood meal from an infected mouse, they pick up the bacteria and carry it for the rest of their lives — meaning they can now pass it on to your pets or your family.
The numbers here are eye-opening: a single infected mouse can pass Lyme disease bacteria to 40–90% of the young ticks that feed on it.
Why Your Yard Might Be a Tick Hotspot
You don’t need to live near a forest to be at risk. Ticks just need three things: cover, moisture, and a nearby host to feed on — and most yards check all three boxes, especially near the edges.
Here’s what the research shows about where ticks actually hang out:
- About 75% of tick bites happen right at home, outdoors
- Ticks cluster heavily near the edge of the lawn, where grass meets woods, bushes, or stone walls — 82% of young ticks are found within about 10 feet (3 meters) of that edge
- Ticks are most common in wooded areas (67%) and the brushy edge zones (22%) — only about 2% are found out in the open lawn
This lines up with how mice behave, too. A white-footed mouse typically only roams a quarter- to two-and-a-half acres — which means a mouse living at the edge of your yard could be responsible for infecting many of the ticks nearby.
“I Got Rid of the Mice — Aren’t I Done?”
Not quite, and this part is important. If you deal with a mouse or rat problem but don’t also deal with the ticks living on those rodents, something unexpected can happen: ticks that were feeding on the rodent will detach once it’s gone and look for a new source of blood — which could be you, your kids, or your pets. In other words, removing rodents without addressing their ticks can actually raise your short-term risk of exposure, right when you thought you’d solved the problem.
A Better Way: Treat the Source, Not Just the Symptom
This is exactly the gap Kaput® Rodent & Tick Bait is designed to close. Instead of treating “rodents” and “ticks” as two separate problems that need two separate products, it tackles both at the same time, in one bait.
Here’s how it works, in simple terms:
- Rodents eat the bait, which contains two active ingredients: warfarin (which controls the rodent population) and a very small, safe amount of fipronil (0.005%), a common ingredient also used in flea and tick treatments for pets.
- As the rodent feeds on the bait, the fipronil also gets into the ticks living on that rodent — controlling the ticks directly on their main host.
- This breaks the disease cycle early, before those ticks ever have the chance to spread to your lawn, your pets, or your family.
Do I Need to Cover My Whole Yard?
Not necessarily. Because mice stick to such a small home range, you don’t need dozens of bait stations scattered everywhere. A few well-placed bait stations placed strategically — especially near the wooded or brushy edges of your property, where mice and ticks naturally concentrate — can effectively cover a typical residential yard.
The Bottom Line
Tick and Lyme disease risk doesn’t start in the forest — it starts with the rodents living just outside your back door. By targeting the rodents and the ticks riding along on them, Kaput® Rodent & Tick Bait offers a more complete way to protect your yard, before the risk ever reaches your doorstep.
