Feels great!
Size: 5 Ounce (Pack of 1)
Big spray is never 100% proof, but this gets 5 stars because it’s one of the best bug sprays I’ve used. It doesn’t feel sticky. Women will appreciate this - it doesn’t burn on newly-shaved legs either! The smell isn’t too bad either. I actually bought this because my friend had it while camping in FL a couple weeks ago. We all really liked it.

Really works for toddler who is allergic to bug bites
Size: 5 Ounce (Pack of 1)
My 1 year old grandson was always covered with huge swollen bug bites when I used other bug repellents. Now his skin is clear. Will make you cough if you breathe it in but otherwise quick and easy to use. Scent less and not sticky at all. Can doesn’t seem to last long. Lotion is also good.

Strong Family Protection — With Some Minor Trade‑Offs
Size: 5 Ounce (Pack of 1)
I’ve been using OFF! Insect Repellent Aerosol for Adults & Kids (Fragrance‑Free / Picaridin variant, 5 oz) for outdoor family time, and overall it’s been a solid choice. Here’s how it stacks up:
👍 What Works Really Well
1. Good protection, kid‑friendly too
The formula is designed for both adults and children ages 1 year and up, when used as directed. For kids between 1 and 10 years, usage is limited (you don’t want to overapply).
It does a strong job of keeping mosquitoes, ticks, and biting flies away. We spent hours outdoors and did not come back with a swarm of bites. 
2. Feels pleasant — non‑greasy, low residue
A big plus: it doesn’t leave skin feeling sticky, oily, or greasy. That’s always a win when you’ve got wiggly kids who won’t sit still for long. The scent is mild (especially in the fragrance‑free version), and it dries fairly quickly.
3. Long enough duration
You get about 6 hours of protection against mosquitoes (when applied properly). That’s plenty for a few hours in the yard, a picnic, or a short hike.
4. Easy spray application
The aerosol format means you can cover exposed skin and clothing fairly quickly. It’s good for when you need full‑body coverage or you’re applying while kids are wriggly.
👎 What to Be Careful Of / Possible Downsides
1. Must follow directions carefully with young kids
Because the product is strong enough for adults, when using on young children (especially 1‑10 years old), it should be applied sparingly and no more than twice per day on kids. Avoid sensitive areas (eyes, mouth, hands).
2. Spray drift / inhalation concerns
Some users report that spray fumes are noticeable, and in some cases—especially in confined spaces or windy conditions—the aerosol mist can get in kids’ faces or mouths, which is uncomfortable. Spraying in open air and avoiding spraying near the face helps.
3. Reapplication needed if in heavy perspiration or after swimming
Like most insect repellents, you lose effectiveness faster when the skin is wet, or when there’s lot of sweat, or after swimming. So you’ll need to reapply more often under those conditions. Not unique to this product, but worth noting.
4. Aerosol form handling
Because it’s aerosol, you’ll want to handle with care. Spray evenness, avoiding over‑spraying, and storing safely are important. Also: don’t let kids handle it by themselves.
⚖️ Verdict
If you’re looking for a reliable insect repellent that’s strong enough for adult use and safe enough for kids (1 year+), this OFF! aerosol is one of the better options out there. It hits a nice balance: effective, relatively gentle on skin, and convenient. For families who spend time outdoors — hiking, camping, playing — it’s a worthwhile investment.
I’d give it 4 out of 5 stars: loses a bit for aerosol odor and needing care with application, but wins big on protection and usability.

Easy for kids to use
Size: 5 Ounce (Pack of 2)
My son uses this when he's outside because constantly gets bites. He's 7 and can spray it himself and no bites when he uses it. Would highly recommend. Does linger in the air after so I don't recommend using in the garage
