How to Get Rid of Ants and Spiders Naturally & Effectively (2026 Guide)
Ants and spiders are among the most common household pests, especially during warmer months. The good news? You can control them safely without harsh chemicals. This guide covers proven natural remedies, prevention tips, and when to call professionals.
Why Ants and Spiders Invade Your Home
- Ants come for food, water, and shelter. They follow pheromone trails and can quickly form colonies.
- Spiders follow their prey (often ants or other small insects) and seek dark, undisturbed corners.
Tackling both together is smart because reducing insects reduces spiders.
Top Natural Remedies for Ants
- White Vinegar Spray (Most Popular) Mix equal parts white vinegar and water in a spray bottle. Spray directly on ants and along their trails, baseboards, windowsills, and entry points. Why it works: Disrupts scent trails and kills on contact.
- Borax + Sugar Bait (Colony Killer) Mix 1 part Borax with 3 parts powdered sugar. Add a little water to make a paste and place on lids or cards near trails (away from pets/kids). Ants carry it back to the nest.
- Food-Grade Diatomaceous Earth (DE) Sprinkle a thin layer around entry points, baseboards, and ant hills. Safe for humans/pets when using food-grade version. It dehydrates insects.
- Essential Oil Repellents
- Peppermint, tea tree, lemon eucalyptus, or orange oil. Mix 10–15 drops with water + a splash of dish soap in a spray bottle.
- Other Kitchen Heroes
- Lemon juice or peels
- Cinnamon or cayenne pepper (sprinkle barriers)
- Used coffee grounds
- Baking soda + powdered sugar
Best Natural Solutions for Spiders
- Peppermint Spray Mix water, a few drops of dish soap, and 15–20 drops of peppermint essential oil. Spray in corners, windows, and doorways.
- Vinegar Solution 1 part vinegar to 9 parts water. Spray directly on spiders or webs.
- Reduce Insect Food Sources Fewer ants and bugs = fewer spiders.
- Natural Repellent Plants Place lavender, mint, eucalyptus, or citronella near entrances.
- Diatomaceous Earth Works on spiders too when they crawl through it.
Comparison Table: Natural Remedies
| Remedy | Best For | Effectiveness | Pet/Kid Safe? | Duration |
|---|---|---|---|---|
| Vinegar Spray | Ant trails | High (repels) | Yes | Short-term |
| Borax + Sugar | Ant colonies | Very High | Caution | 1–2 weeks |
| Peppermint Oil Spray | Spiders & Ants | High | Yes | 3–7 days |
| Diatomaceous Earth | Both | High | Yes | Long (dry) |
| Essential Oils | Repelling | Medium-High | Yes | Needs reapply |
Prevention Tips (Most Important Step)
- Seal entry points: Caulk cracks around windows, doors, and pipes.
- Clean regularly: Wipe surfaces, store food in airtight containers, and take out trash often.
- Reduce moisture: Fix leaks and use dehumidifiers in damp areas.
- Declutter: Spiders love boxes, piles of clothes, and wood stacks.
- Outdoor maintenance: Trim bushes away from the house and clear debris.
- Yard lighting: Use yellow bulbs — they attract fewer insects.
When to Call a Professional
Try natural methods for 1–2 weeks. Call an exterminator if:
- You see large numbers of ants returning daily.
- You find carpenter ants (they damage wood).
- Spiders are venomous types (e.g., black widow, brown recluse) or the infestation is severe.
- Natural remedies stop working.
Safety Notes
- Always keep Borax baits away from children and pets.
- Test essential oil sprays on small areas first.
- Ventilate when spraying.
Final Recommendation Start with vinegar cleaning + peppermint spray for quick results, then use Diatomaceous Earth and baits for longer control. Consistency is key!
