Chigger Bites: How Long They Last and What to Do

Quick answer

• Chigger bites usually last 1 to 2 weeks.
• They itch like crazy, but resist the urge to scratch.
• Wash thoroughly after being in chigger territory.
• Use insect repellent with DEET or picaridin.
• Treat bites with anti-itch creams and cool compresses.
• See a doctor if you suspect infection or a severe reaction.

What to check first (do this before you drive out)

Before you head out into the wild, where chiggers are known to lurk, a little prep goes a long way. Don’t get caught off guard.

• Land manager / legality: Know who manages the land you’re visiting. Is it National Forest, BLM, State Park, or private? Different agencies have different rules about camping, fires, and even what you can bring. A quick look at their website is usually all it takes. I usually check the US Forest Service or BLM pages for dispersed camping spots.

• Access/road conditions: This is crucial. Are the roads leading to your spot paved, gravel, or just a suggestion? If you’re in a 2WD car, you might be stuck miles from your destination. Check recent trip reports or call the ranger station if you’re unsure. Don’t be the guy who needs a tow out of the mud.

• Fire restrictions + weather + wind: Always check current fire restrictions. A campfire is great, but not if it gets you a hefty fine or worse. Also, check the weather forecast. Rain can turn dirt roads into quagmires, and high winds are a no-go for campfires and even tents.

• Water plan + waste plan (Leave No Trace): If you’re going primitive, you need to know where you can safely get water and how you’ll treat it. And for waste, remember LNT principles. Pack it in, pack it out. No exceptions. This means your trash, and whatever else nature doesn’t need.

• Safety (wildlife, distance to help, comms): Be aware of local wildlife. Know what to do if you encounter a bear or snake. How far are you from the nearest town or ranger station? Do you have cell service? A satellite communicator is a solid backup for remote areas.

Step-by-step (field workflow)

Here’s how to handle chiggers when you’re out camping. It’s about prevention and then dealing with the aftermath.

1. Identify potential chigger habitats:

• What to do: Learn where chiggers like to hang out. Think tall grass, brushy areas, and overgrown fields, especially near woods.
• What “good” looks like: You can spot these areas and steer clear of them when setting up camp or hiking.
• Common mistake: Wandering blindly into dense, overgrown areas without thinking. Avoid this by looking for the tell-tale signs of thick vegetation.

2. Apply repellent before entering chigger zones:

• What to do: Use an EPA-registered insect repellent containing DEET, picaridin, or permethrin on your clothing and exposed skin.
• What “good” looks like: You’ve got a solid barrier against these tiny pests.
• Common mistake: Forgetting to apply repellent or only spraying a little. Be thorough; these bugs are small but mighty.

For effective protection, consider using an EPA-registered insect repellent like this DEET insect repellent on your clothing and exposed skin.

3. Wear protective clothing:

• What to do: Tuck your pants into your socks and wear long sleeves. Consider treating your clothing with permethrin spray before your trip.
• What “good” looks like: You’ve created a physical barrier that chiggers can’t easily penetrate.
• Common mistake: Wearing shorts and short sleeves in known chigger areas. This is basically an open invitation.

4. Inspect yourself and gear after activity:

• What to do: After hiking or spending time in tall grass, do a thorough check of your body, clothes, and gear. Look for any tiny red or orange specks.
• What “good” looks like: You catch any hitchhikers before they find a good spot to bite.
• Common mistake: Skipping this check, thinking “I’m fine.” Chiggers are sneaky.

5. Shower immediately upon returning to camp/home:

• What to do: As soon as you get back to your campsite or home, take a hot shower. Scrub your skin thoroughly with soap.
• What “good” looks like: You’ve washed off any chiggers that might have been on your skin before they could bite.
• Common mistake: Delaying your shower. The longer you wait, the more likely they are to have found a feeding spot.

6. Wash all clothing and gear:

• What to do: Launder all the clothes you wore, as well as any gear that might have picked up chiggers, in hot water.
• What “good” looks like: Any lingering chiggers are killed in the wash.
• Common mistake: Putting potentially infested clothes in the dryer without washing first. Some might survive the dryer heat if not properly washed.

7. Treat chigger bites:

• What to do: If you do get bitten, resist the urge to scratch. Apply calamine lotion, hydrocortisone cream, or a paste of baking soda and water to relieve itching.
• What “good” looks like: The itching is managed, and you’re not breaking the skin.
• Common mistake: Scratching the bites until they bleed. This is how you invite infection.

8. Monitor for infection:

• What to do: Keep an eye on the bites for signs of infection like increased redness, swelling, pus, or fever.
• What “good” looks like: Bites are healing without complications.
• Common mistake: Ignoring signs of infection, thinking it’s just normal itchiness. If it looks bad, it probably is.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not using repellent in chigger areas	Bites, intense itching, potential secondary infections from scratching.	Apply EPA-approved repellent to skin and clothing before entering chigger habitats.
Wearing shorts/short sleeves in tall grass	Direct exposure, leading to multiple bites and widespread itching.	Wear long pants tucked into socks and long-sleeved shirts.
Skipping post-activity inspection	Chiggers can hitch a ride back to your tent or home, biting you later.	Do a thorough body and gear check after any time spent in grassy or brushy areas.
Delaying your post-activity shower	Chiggers have more time to attach and feed, increasing bite severity.	Shower with soap and water as soon as possible after leaving chigger-infested areas.
Scratching chigger bites	Broken skin, increased risk of bacterial infection, scarring.	Resist the urge. Use anti-itch creams, cool compresses, or oral antihistamines.
Not washing infested clothing properly	Chiggers can survive and re-infest you or others.	Wash all contaminated clothing and gear in hot water and dry on a hot cycle.
Misidentifying chigger bites as something else	Delayed or incorrect treatment, prolonged discomfort.	Learn what chigger bites look like (small red bumps, intense itch) and their typical locations.
Assuming repellent works forever	Repellent effectiveness wears off, especially with sweat and activity.	Reapply repellent as directed by the product label, especially after swimming or heavy sweating.
Not treating the itch effectively	Sleep deprivation, constant distraction, and increased likelihood of scratching.	Use a combination of topical treatments and consider oral antihistamines for severe itching.
Ignoring signs of infection	Worsening condition, need for medical intervention (antibiotics, etc.).	See a doctor if bites become significantly red, swollen, painful, or if you develop a fever.

To avoid bites and intense itching, make sure to apply an EPA-approved repellent, such as this DEET insect repellent, to your skin and clothing before entering chigger habitats.

Decision rules (simple if/then)

• If you are going to be in an area known for tall grass or brush, then you need to apply insect repellent because chiggers thrive in these environments.
• If you are wearing shorts and t-shirts in a grassy field, then you are making yourself a prime target for chigger bites because exposed skin is an easy entry point.
• If you feel an itch after being outdoors in a likely chigger area, then it’s probably a chigger bite because their bites are intensely itchy.
• If you are considering scratching a chigger bite, then you should stop yourself immediately because scratching can lead to infection and scarring.
• If you are going to camp near woods or in a meadow, then you should check for local chigger activity reports because some areas are worse than others.
• If you have just returned from a known chigger habitat, then you should shower as soon as possible because washing them off before they bite is the best defense.
• If you are planning a hike through overgrown trails, then treating your clothing with permethrin is a good idea because it provides an extra layer of protection.
• If you see red, swollen, or pus-filled bumps after being outdoors, then you should seek medical advice because these could be signs of an infected chigger bite.
• If you are in an area with high chigger populations, then consider wearing gaiters over your boots and pants because this creates a physical barrier.
• If you are experiencing severe itching that disrupts sleep, then an oral antihistamine might be necessary because topical treatments may not be enough.
• If you are packing for a camping trip in summer, then insect repellent should be at the top of your list because chiggers are most active during warmer months.
• If you are unsure about the best repellent, then look for products containing DEET or picaridin because these are proven effective against chiggers.

If you are packing for a camping trip in summer, insect repellent should be at the top of your list. Look for products containing DEET or picaridin, like this DEET insect repellent, as they are proven effective against chiggers.

FAQ

How long do chigger bites usually last?

Chigger bites typically itch for about 1 to 2 weeks. The intense itching usually subsides before the red bumps disappear completely.

Can chiggers stay on you for days?

While chiggers attach to feed, they usually drop off within a few days. The bites, however, will continue to itch for much longer.

How do I know if it’s a chigger bite?

Chigger bites usually appear as small, red, intensely itchy bumps, often clustered on ankles, legs, or around the waistband. They’re different from mosquito bites, which tend to be more localized welts.

What’s the fastest way to get rid of chigger bites?

There’s no instant cure, but prompt showering and applying anti-itch creams like calamine or hydrocortisone can significantly reduce the discomfort and duration of the itch.

Should I pop chigger bites?

Absolutely not. Popping or scratching chigger bites will not make them go away faster and significantly increases the risk of infection and scarring.

Are chigger bites dangerous?

In the US, chigger bites are generally not dangerous, though they are extremely irritating. They don’t transmit diseases here.

When are chiggers most active?

Chiggers are most active during the warmer months, typically from late spring through early fall, especially in humid conditions.

Can chiggers get in my tent?

Yes, chiggers can hitch a ride on your clothing or gear and end up in your tent. Always inspect your gear and shake out your sleeping bag before settling in.
