Top Picks: Your Go-To Plants to Keep Flies Away Indoors

Now for the exciting part! Let’s explore some of the most effective and easiest-to-grow plants to keep flies away indoors. Trust me, these selections are perfect for gardeners of all levels, from absolute beginners to seasoned green thumbs.

When thinking about how to plants to keep flies away indoors, remember that their strong natural oils and scents are what do the trick. Flies, with their sensitive antennae, find these aromas overwhelming and choose to steer clear.

Basil (Ocimum basilicum)

Oh, basil! More than just a culinary herb, this fragrant plant is a fantastic fly deterrent. Its strong, spicy aroma, so appealing to us, sends flies packing.

Care Guide: Basil loves sunlight, so place it in a south-facing window where it can soak up at least six hours of direct light daily. Keep its soil consistently moist, but not waterlogged, and pinch off flower buds to encourage bushy growth and maximize its repellent power.

Mint (Mentha spp.)

Mint varieties like peppermint and spearmint are powerhouse fly repellents. Their robust, fresh scent is a natural enemy to many insects, including flies and even mosquitoes.

Care Guide: Mint is incredibly vigorous and can be grown in a pot indoors to keep its spreading habit in check. It prefers bright, indirect light and consistently moist soil. Regular harvesting (clipping leaves) will keep it healthy and productive.

Lavender (Lavandula angustifolia)

Ah, lavender. Its beautiful purple blooms and calming aroma are legendary. What’s not so well-known is its effectiveness against flies, moths, and even fleas. The compounds linalool and linalyl acetate are the secret.

Care Guide: Lavender needs lots of sun – at least 6-8 hours daily – so a sunny windowsill is a must. It prefers well-draining soil and can tolerate drier conditions once established. Avoid overwatering; let the soil dry out between waterings.

Rosemary (Rosmarinus officinalis)

This woody herb, with its pine-like fragrance, is another excellent choice for your indoor fly-fighting arsenal. Its scent is a natural repellent, and it’s also wonderfully versatile in the kitchen.

Care Guide: Rosemary thrives in bright, direct sunlight and prefers well-draining soil. It’s a bit more drought-tolerant than some other herbs, so let the top inch or two of soil dry out before watering again. Good air circulation is key to preventing fungal issues.

Lemon Grass (Cymbopogon citratus)

Often mistaken for citronella grass (which is a close relative), lemon grass contains citral, a powerful compound found in citronella oil. This zesty scent is a proven fly and mosquito repellent.

Care Guide: Lemon grass loves warmth and plenty of sunshine. Give it a large pot and place it in your sunniest window. Keep the soil consistently moist. It’s relatively low-maintenance and will grow into an impressive clump.

Marigolds (Tagetes spp.)

While often seen outdoors, smaller varieties of marigolds, particularly French marigolds, can do well indoors in a bright spot. They release pyrethrum, a natural compound used in many commercial insect repellents, which deters flies and other pests.

Care Guide: Marigolds need bright, direct sunlight to bloom profusely. Water regularly, ensuring the soil is moist but not waterlogged. Deadhead spent blooms to encourage continuous flowering and maximum repellent power.

Venus Flytrap (Dionaea muscipula)

Okay, this one is a bit different! Instead of repelling, the Venus flytrap actively *eats* flies. If you have specific fly problems, especially with larger house flies, this carnivorous plant can be a fascinating and effective solution.

Care Guide: Venus flytraps require specific care: bright, direct sunlight, distilled or rainwater (tap water can harm them), and consistently moist soil. They also need a period of dormancy in winter. Don’t “feed” them meat or cheese; they’ll catch their own meals!

Citronella Geranium (Pelargonium citrosum)

Often marketed as the “mosquito plant,” this geranium also has a potent, lemony scent that flies dislike. While it doesn’t contain true citronella oil, its fragrance is quite effective.

Care Guide: Citronella geraniums prefer bright, indirect light and well-draining soil. Allow the topsoil to dry out slightly between waterings. Pinch back leggy growth to encourage a bushier, more fragrant plant.

Bay Laurel (Laurus nobilis)

The leaves of the bay laurel tree, commonly used in cooking, contain compounds that flies find off-putting. Growing a small bay tree indoors can add both culinary and pest-repelling benefits.

Care Guide: Bay laurel prefers bright, indirect light and consistent moisture. It’s a relatively slow grower but can become a beautiful, fragrant shrub over time. Prune as needed to maintain shape and harvest leaves.

Catnip (Nepeta cataria)

Known for driving cats wild, catnip contains nepetalactone, a compound that is even more effective than DEET at repelling mosquitoes. It’s also highly effective against flies!

Care Guide: Catnip is easy to grow and thrives in full sun to partial shade. It’s quite drought-tolerant once established but appreciates regular watering. Just be prepared for potential feline visitors if you have cats!

Essential Care Guide for Your Fly-Repelling Plants

To truly get the most out of your plants to keep flies away indoors, understanding their basic needs is crucial. A happy, healthy plant is a potent plant! This plants to keep flies away indoors care guide will give you the foundational knowledge you need.

Light Requirements: The Sun’s Embrace

Most of these fly-repelling plants, especially the herbs, thrive in bright, direct sunlight. Aim for at least 4-6 hours of direct sun daily. A south-facing window is often ideal.

If you don’t have enough natural light, consider supplementing with a grow light. It can make all the difference in keeping your plants strong and their repellent oils potent.

Watering Wisdom: Just Right, Not Too Much or Too Little

The biggest mistake new plant parents make is overwatering. Always check the soil moisture before watering. Stick your finger about an inch or two into the soil.

  • If it feels dry, it’s time to water.
  • If it’s still moist, wait a day or two.

Ensure your pots have drainage holes to prevent root rot. Consistency is key, but don’t drown your plants!

Soil & Potting: The Foundation for Growth

Good drainage is paramount. Use a high-quality potting mix that’s well-aerated and drains quickly. For herbs, a mix designed for edibles or a general all-purpose mix with added perlite or sand works well.

Choose a pot that’s appropriately sized. A pot too large can hold too much moisture, while one too small can restrict root growth.

Fertilization: A Little Boost

Most of these plants aren’t heavy feeders. A balanced liquid fertilizer, diluted to half strength, applied every 4-6 weeks during the growing season (spring and summer) is usually sufficient.

Avoid fertilizing during winter when plants are typically less active. Remember, too much fertilizer can burn roots.

Pruning for Potency and Health

Regular pruning isn’t just about shaping; it encourages bushier growth and increases the production of those aromatic oils that deter flies. Pinch back leggy stems and harvest leaves regularly.

For flowering plants like marigolds and lavender, deadhead spent blooms to encourage more flowers and prevent the plant from putting energy into seed production.

Strategic Placement: Where to Put Your Plants to Maximize Fly Repellence

Knowing how to plants to keep flies away indoors isn’t just about choosing the right varieties; it’s also about smart placement. Think like a fly: where do they enter? Where do they congregate?

Placing your plants strategically will create an invisible barrier, making your home less inviting for these unwelcome guests. This is one of the best plants to keep flies away indoors tips I can give you!

Entry Points: Windows and Doors

Flies often enter through open windows and doors. Place your most potent plants, like basil, mint, or lemongrass, directly on windowsills or near doorways.

A small grouping of plants can create a more robust “scent shield” at these critical entry points.

Kitchen and Dining Areas

The kitchen is a prime target for flies, especially fruit flies, attracted to food odors. Place herbs like basil, rosemary, and mint on your kitchen counter or windowsill.

For dining areas, a potted lavender or geranium can add a touch of elegance while keeping pests at bay.

Grouping for Greater Effect

Don’t be afraid to group several different fly-repelling plants together. A combination of scents can be more powerful than a single plant alone.

Plus, a cluster of plants often looks more lush and appealing!

Consider Air Circulation

While strong scents are good, too much stagnant air can lead to plant problems. Ensure your plants have good air circulation around them, especially if they are grouped.

This also helps to gently waft their repellent aromas throughout the room.

Common Problems with Plants to Keep Flies Away Indoors & How to Solve Them

Even the most experienced gardeners face challenges. When you’re using plants to keep flies away indoors, you might encounter a few hiccups. Don’t worry—these common problems are usually easy to fix!

My Plants Aren’t Thriving! (Yellow Leaves, Wilting)

This is often a sign of incorrect watering or insufficient light.

  • Yellow Leaves: Usually indicates overwatering or lack of nutrients. Check soil moisture and ensure good drainage. If consistently wet, repot with fresh, well-draining soil. If dry, consider a light fertilization.
  • Wilting: Can be either too much or too little water. Feel the soil. If bone dry, water thoroughly. If soggy, you’ve overwatered; let it dry out completely before watering again.
  • Leggy Growth: Often a sign of not enough light. Move your plant to a brighter spot or supplement with a grow light.

Flies Are Still Present! What Gives?

Sometimes, even with the best plants, a few persistent flies might linger. Here are a few things to consider:

  • Source of Attraction: Are there other factors attracting flies? Overripe fruit, uncovered trash, or pet waste can override plant repellents. Address these sources first.
  • Type of Fly: Some plants are more effective against certain types of flies. For fruit flies, specific plants like basil or mint can help, but removing the fruit source is paramount. For larger house flies, carnivorous plants like the Venus flytrap can complement your repellent plants.
  • Concentration: You might need more plants, or larger, more mature plants, to create a strong enough scent barrier.

Pests on My Fly-Repelling Plants? The Irony!

Yes, even fly-repelling plants can get other pests. Common indoor culprits include:

  • Aphids & Spider Mites: Look for tiny insects on stems and under leaves. Treat with a gentle insecticidal soap spray or neem oil.
  • Fungus Gnats: These tiny, harmless flies are attracted to overly moist soil. Let the top layer of soil dry out completely between waterings to deter them.

Regularly inspect your plants for any signs of trouble. Early detection is key!

Pet Safety Considerations

While many of these herbs are generally safe, some plants can be mildly toxic to pets if ingested in large quantities. Always research specific plant toxicity if you have curious furry friends.

For example, while basil and mint are generally safe, large amounts of lavender or rosemary could cause mild digestive upset. Place plants out of reach if you’re concerned.
