Powerful Scents and Smells to Repel Mosquitos, Ants, Roaches, and Other Pesky Insects

Exploring Smells and Scents That Repel Insects

Dealing with pesky insects like mosquitos, flies, ants, and cockroaches can be extremely frustrating. When looking for ways to prevent and repel them from your home and outdoor living spaces, considering scents and smells they dislike can be an effective strategy.

How Smells Deter Bugs

Insects detect smells and odors using sensory receptors. Strong, pungent fragrances can overwhelm their sense of smell, essentially repelling them from an area, person, or object that releases the scent.

This works because the potent aromas mask attractive smells and chemical signals that insects use to locate humans and food sources. Additionally, some specific plant extracts and oils contain chemical properties that insects find offensive or disruptive.

Research shows some of the top smells and oils that common home and garden insects dislike include:

• Mint - repels ants, spiders, cockroaches
• Citrus - repels roaches, moths, mosquitos, house flies
• Cedar - repels moths, fleas, roaches, spiders
• Peppermint - repels ants, spiders, beetles, mosquitos

Essential Oil Insect Repellent Recipes

Using pure essential oils is one of the most effective ways to harness the insect-repelling power of scents. Some oil-based recipes to try:

Household Bug Spray

• 5 drops lemongrass oil
• 5 drops eucalyptus oil
• 2 oz witch hazel

Mix together in a glass spray bottle. Spray around doorways, window frames, and anywhere insects enter.

Outdoor Mosquito & Tick Deterrent

• 6 drops citronella oil
• 6 drops peppermint oil
• 6 drops lemongrass oil
• 3 oz carrier oil like olive or coconut oil

Combine in a jar and rub onto skin before going outside.

Natural Pest Control for Plants

• 1 drop rosemary oil
• 1 drop thyme oil
• 1 drop peppermint oil
• 1 gallon water

Stir together in a watering can and apply to soil and foliage to prevent infestations without harsh chemicals.

Moth & Roach Repelling Sachets

Small fabric sachets filled with insect repelling dried herbs can keep moths, beetles, roaches, and silverfish out of closets and pantries. Try stuffing small cotton muslin bags with:

• Lavender
• Rosemary
• Cedar chips
• Dried lemon and orange peel
• Whole cloves

For maximum impact over time, squeeze bags every few weeks to release more aroma.

Vinegar as an Insect Deterrent

Plain white distilled vinegar makes an effective DIY repellent for crawling insects like ants and cockroaches. Solutions to try:

• Equal parts vinegar & water spray - Apply along baseboards and doorway cracks
• Jar lids lined with cotton balls soaked in vinegar - Set out in problem areas around the home
• 1 part vinegar mixed with 2 parts water in a spray bottle - Mist onto plants to keep off aphids and spiders

The acetic acid provides a strong scent that irritates insects and interferes with their ability to pick up food odors.

Why Citronella Repels Insects

Often used in commercial bug sprays and candles, oil derived from the citronella plant contains geraniol and citronellal compounds that are highly unpleasant and overwhelming for mosquitos. Reviews confirm citronella:

• Masks carbon dioxide and sweat compounds that attract biters
• Impacts mosquito sense of smell to deter feeding
• Repels 83% of Aedes species, including aggressive Asian tiger mosquitos

Use 100% pure citronella oil or blended oil formulas for best repellency.

Natural Insect Repellents Around Your Home

Aside from scented sprays and sachets, there are some simple tricks to deter common household pests.

Ants Hate These Smells

Unwelcome ants streaming into your kitchen can quickly become a nuisance. Stop them by placing small dishes of dry herbs and spices where they enter, including:

• Ground black pepper
• Cinnamon
• Paprika
• Crushed mint leaves
• Chili powder
• Cloves
• Castor oil

These strong scents confuse ants' smell receptors causing them to lose their trail and turn away.

Use Mint to Keep Spiders Out

While not foolproof for all species, mint and menthol smells can deter spiders from setting up webs in unwanted areas like patios, garages, and covered porches. Tactics include:

• Planting mint bushes around the perimeter
• Setting out cotton balls soaked with peppermint oil
• Spraying diluted mint oil in corners and ceilings

The mint smell masks the insect chemical trails spiders follow when constructing webs in prime spots.

Repel Pantry & Cabinet Moths

Tiny stored product moths can contaminate dry goods like flour, pasta, oats, birdseed, and more. Strategically placing pantry moth traps can stop infestations before they start.

• Cedar blocks deter egg laying adults
• Lavender or eucalyptus sachets prevent larvae from developing
• Pheromone sticky traps capture male moths looking to mate with females

Use these smelly deterrents in cupboards, drawers, and anywhere you store dry food to proactively block moths.

Outdoor Insect Control With Scent

Scent can also help minimize annoying insects that congregate in entryways as well as backyards and patios.

Potted Pest Repellents

Certain plants naturally release smells that keep flying and crawling insects out of outdoor living areas. Effective container garden pest deterrents include:

• Marigolds
• Chrysanthemums
• Basil
