For decades, households around the world have relied on a low‑tech, grandma‑approved kitchen remedy to chase away both flies and cockroaches—without resorting to harsh pesticides. While the original version of this trick has circulated online in various forms, here’s a fully rewritten, expanded guide offering the method, its science, safety tips, and additional natural strategies to ensure your home stays critter‑free. (Quotes from original advocates are preserved as requested.)
The Classic Natural Trick: Apple Cider Vinegar + Dish Soap Jar Trap
Why it works: A shallow container (like a jar or bowl) filled with apple cider vinegar—sweetened slightly and topped with a few drops of dish soap—lures flies in and prevents them from escaping. The vinegar aroma attracts flies and gnats, the dish soap breaks the surface tension, and they drown harmlessly. It’s also effective for smaller cockroach species that crawl near the trap. This method is 100% natural, safe for homes with pets or kids, and easy to assemble with basic kitchen staples.Sophia’s Cleaning Service+1Facebook+1
How to make it:
- Pour about an inch of apple cider vinegar into a clean jar or shallow bowl.
- Add 2–4 drops of dish soap. Optionally, sprinkle a small pinch of sugar to increase attraction.
- Stretch a piece of plastic wrap over the top and secure it with a rubber band.
- Poke several small holes (pencil‑tip size) above the liquid level so insects can crawl in but can’t climb back out.
- Place traps near likely entry points—kitchens, trash bins, drains, windows.
Flies and small crawling insects go in and drown in the soapy vinegar. Replace every few days or when full.
Adding More Punch: Baking Soda + Water Paste for Roaches
If you’re combating crawling pests such as roaches, combine baking soda with water to form a paste and apply it to dark corners, behind appliances, and in kitchen cabinet cracks. The baking soda disrupts the insects’ digestive pH balance, while water helps it stick. When cockroaches ingest it, they die naturally—without harsh toxins.YouTube+2Sophia’s Cleaning Service+2Reddit+2Reddit
Why It Works: The Science Behind the Hack
- Apple cider vinegar emits acetic acid, which flies and fruit flies—especially—find attractive. Once in contact, they cannot resist getting too close.
- Dish soap reduces surface tension, causing insects to sink instead of landing safely.
- Cockroaches exploring surfaces may step into the mixture and perish.
- Baking soda acts as a desiccant and digestive disruptor for roaches.
- All ingredients are non-toxic (food grade), biodegradable, pet-safe (when used sparingly), and breathable.
Quotes That Reinforce This Approach

Beyond the Jar: Complementary Natural Measures
1. DIY Soapy Spray
Fill a spray bottle with water and a few drops of dish soap (or isopropyl alcohol). Use as a quick knockout spray for flies that land visibly. The mixture clogs their breathing spiracles. Effective, humane, and chemical‑free.Sophia’s Cleaning Service+3Reddit+3Facebook+3
2. Sticky Fly Paper or Traps
Hang fly paper or adhesive strips near windows, doorways, or garbage zones. Flies land and get instantly stuck. Rotate or replace strips once filled.Sophia’s Cleaning Service
3. Essential Oil Sprays & Herbs
Flies and roaches dislike natural scents such as lavender, peppermint, lemongrass, eucalyptus, and orange peels. Mix essential oils with water in spray bottles or leave bits of citrus peel near suspected entry points.Sophia’s Cleaning Service
4. Sugar‑Yeast CO₂ Traps (Outdoor Option)
Cut the top of a plastic bottle, invert it, and pour in warm water with sugar and a teaspoon of yeast. The CO₂ bubbles attract flies into the funnel, and they can’t escape. Place outdoors in shaded areas near doors/windows.Sophia’s Cleaning Service
5. Mind the Hygiene
- Wipe kitchen surfaces, counters, floors, and under appliances regularly.
- Rinse all dishes and clean drains.
- Remove crumbs immediately.
- Store boxed or dry food in sealed glass/plastic containers. Cardboard is roach food.YouTube+4Reddit+4Reddit+4Facebook
6. Prevent Moisture
Eliminate standing or pooled water—also a breeding site for bluebottle flies, drain flies, and cockroaches. Keep sinks, planters, and pet bowls clean and dry. Fix leaks promptly.Reddit
Putting It All Together: Step‑by‑Step Routine
| Step | Action |
|---|---|
| 1. Prepare Traps | Set apple cider vinegar + soap jars throughout kitchen and waste zones. |
| 2. Apply Paste | Use baking soda paste in crevices and under corners. |
| 3. Keep Clean | Wipe counters, sweep floors, clean sinks & drains daily. |
| 4. Use Sprays | Use soapy spray or essential oil mix for random sightings. |
| 5. Remove Waste | Empty trash frequently; rinse and dry bins weekly. Store food sealed. |
| 6. Monitor & Adjust | Replace traps every few days or after heavy catch. Deep clean monthly. |
Safety Tips & Best Practices
- Always wear gloves when handling paste or traps to avoid residue contact.
- Avoid overuse of apple cider vinegar in spaces near wood or decorative surfaces—it can be sticky or stain.
- Use food-grade, unscented dish soap and vinegar (ensure no harsh additives).
- Keep pets and children away from uncovered traps or paste areas. The ingredients are safe, but ingestion should still be avoided.
- If respiratory irritation arises from dust (e.g. baking soda or soap particles), open windows or ventilate during application.
Why Natural Works Better Than Chemicals
- Non-toxic: These methods rely on everyday ingredients without harmful fumes—safe for families and pets.
- Better for the planet: No residual contamination of water or soil like conventional pesticides.
- Cost-effective: Items such as vinegar, soap, baking soda cost pennies, yet can outperform baits or gels.
- Flexible & holistic: These tricks combine attractants, barriers, and deterrents—covering multiple pest behaviors.
Recognizing & Preventing New Infestations
Cockroaches can multiply rapidly—some species lay hundreds of eggs within days. Successful prevention involves:
- Sealing cracks around windows, doors, pipes, utility lines.
- Installing fine-mesh screens or keeping doors shaded.
- Checking for clusters of insects on walls or ceilings.
- Observing foul odors around drains or trash areas.
Combat early sightings aggressively—with traps and hygiene—to prevent small issues from becoming full infestations.
Final Thoughts
This time-tested “old trick” of vinegar‑and‑soap traps combined with simple home hygiene and baking soda controls is not only effective—it’s eco‑friendly, safe, and affordable. Whether you’re contending with persistent flies this summer or a budding roach problem, try this wholesome approach:

If traps still fail to control a severe infestation on their own, contact a professional pest control service—but for most ordinary household breaches, this natural regimen is plenty powerful.
With patience (traps refreshed regularly) and cleanliness, you can reclaim your home pest‑free—and without a spray can in sight.
