Most Silver Spring parents have one date circled: August 25, when Montgomery County classes start. Plan your head check around a different one.

The region doesn’t come back all at once. Loudoun County students return Monday, August 17. Fairfax follows on the 24th. Montgomery County starts instruction Tuesday, August 25. Classrooms across the DMV are trading head-to-head contact a full week before your kid’s bell rings, and a case caught now is a quiet August afternoon instead of a September scramble. Check every head in the house in the last few days before your own first day, not three weeks out and not after the first note comes home.

The Region Comes Back Across Eight Days

Loudoun County adopted the earliest calendar in the region. Its first day of school is Monday, August 17.

Fairfax County welcomes students back on Monday, August 24, a day ahead of Maryland’s largest system.

Montgomery County treats the 24th as a non-instructional Student Transition Day and begins instruction on Tuesday, August 25.

Eight days separate the first kids back in a DMV classroom from the ones here in Silver Spring. That gap matters more than it sounds like it should, because a child’s social circle doesn’t stop at a county line. Cousins in Ashburn. A travel team that practices in Vienna. A neighbor at a private school running its own calendar. Those kids are back in rooms full of heads while your family is still at the pool.

Classrooms concentrate contact in a way summer never does. Desks push kids shoulder to shoulder, phones get shared for a group selfie, and coats pile onto the same hook. That’s how a single head lice infestation works its way through a grade in a few weeks rather than a few months.

Eggs Laid at Camp Won’t Show Up Until School Does

Here’s the part that catches families off guard. Lice eggs don’t announce themselves. The American Academy of Pediatrics puts the timeline plainly: eggs or nits hatch in 7 to 12 days, depending on the surrounding temperature. Nothing itches in the meantime.

Run that clock backward and the last two weeks of summer look different. A child who picked something up during the final week of camp, at a family reunion, or on an August sleepover can have a normal-looking head today. The first real itch tends to arrive in the second week of school, which is also the week that child has met thirty new heads. Parents who checked in mid-July and found nothing often assume they’re clear. They checked before the eggs existed.

That’s the whole case for timing. A check three weeks out answers a question about July. A check on the weekend before the first day answers the question you care about. If your kids just came home from a session away, lice picked up at the end of camp are usually the ones that surface first.

What You Can Handle Yourself This Week

Most of this is a home job, and doing it properly will catch the majority of active cases. No special training required.

  • Work in daylight. A window at four in the afternoon beats any bathroom fixture.
  • Dampen the hair and load it with conditioner. Lice slow down and the comb moves.
  • Use a metal fine-tooth nit comb, not the flimsy plastic one that ships inside a treatment box.
  • Take small sections. Comb from the scalp all the way out, then wipe the comb on a white paper towel and look at what came off.
  • Spend the most time behind the ears, at the nape, along the part, and around the crown.
  • Do every person in the house on the same evening. Adults included.

What you’re deciding is whether a speck is a nit or debris. A nit is cemented to the hair shaft and won’t slide. Dandruff, hairspray, and dry scalp flakes move the moment you push them with a fingernail. If it slides, it isn’t a nit.

Do this once in the days before your district’s first day. Then do it again around the two-week mark.

Where a Kitchen-Table Check Runs Out of Road

Home checking has a ceiling, and pretending otherwise doesn’t help anyone. It gets hard fast on long, thick, curly, or tightly textured hair, because you can’t inspect what you can’t hold apart. It gets harder still on a seven-year-old who is done sitting still.

And it gets hardest at the moment you find something. Live nit or empty casing? Six of them or sixty? That answer changes what happens next, and plenty of parents can’t call it under a kitchen light. A professional head check and comb-out exists for exactly that gap: professional tools, section-by-section work, and a definite yes or no.

One practical detail worth knowing before you book. At our Silver Spring treatment center, the cost of a head check applies toward treatment if lice are found. A clean result costs you a check. A positive result doesn’t cost you twice.

One Visit Beats Four Separate Bathroom Checks

The case that resurfaces in October usually traces back to the person nobody screened. Often that’s an adult who never itched and never got looked at.

Bringing the household in together solves that in one pass. Everyone gets screened during the same visit against the same standard, so you leave knowing where the whole family stands instead of where one kid stands. If someone is positive, the comb-out starts that day rather than after a second round of scheduling.

Our clinic on Fenton Street is open weekdays until 8 p.m. and both weekend days, so you can book head checks for the whole household after work or on a Saturday morning. Nobody has to miss a school day to find out they’re fine.

What Waiting Until the Second Week Costs

Skip the pre-school check and the calendar decides for you.

A case found in August is a scheduling decision. You pick an afternoon that works. A case found in late September is a logistics problem: comb-outs on school nights, homework pushed back, siblings who suddenly need checking, and a note to write to the teacher. The work is the same work. The week you do it in is what changes.

There’s a money side too. One household visit before the year starts is a single appointment. A case that has quietly spread to three heads by October is three treatments plus follow-up checks, landing in the busiest stretch of the fall. Once the year is underway, a check-in rhythm through the school year keeps the gap between exposure and discovery short.

Ready to Clear Every Head Before the First Bell?

You have a little under three weeks before Montgomery County starts, and less than that if one of your kids sits in a Virginia classroom. That’s plenty of time to find out exactly where your household stands.

Lice Lifters of Greater Washington screens and treats at 8115 Fenton St, Suite 214 in Silver Spring, with head checks and a careful comb-out handled in one calm visit. Call (301) 375-2208 or book a head check before the first day.

Frequently Asked Questions

Should we check before the first day or after?

Before, and close to it. A check in the two or three days before your district’s first day gives you a clean baseline and leaves room to fix anything you find without missing school. Check again around the two-week mark, when a case seeded during that first week becomes visible.

Our kids attend schools in two different districts. Does that change anything?

It moves your date earlier. Work from whichever school starts first. If one child walks into a Virginia classroom on August 17 and a sibling starts in Maryland on the 25th, the household’s exposure window opens on the 17th, and both kids should be checked before then.

We checked in July and found nothing. Do we need to do it again?

Yes. Eggs laid in late July would not have hatched yet, and nits sitting within a few millimeters of the scalp are easy to miss on a first pass. A July check tells you about July. Repeat it in the days right before school starts.
