As temperatures rise, so does outdoor living season. Whether you’re grilling on the patio, relaxing on the porch, or hosting friends in the backyard, spring and summer often bring some unwelcome guests: wasps, hornets, mosquitoes, flies, and other nuisance pests.

While chemical pesticides can be effective, many homeowners prefer safer, non-toxic alternatives, especially around children, pets, gardens, and outdoor dining areas. The good news is that there are several simple DIY pest repellents you can make using common household ingredients.

Why Use Non-Toxic Pest Repellents? Chemical insecticides can leave residues on outdoor furniture, plants, and surfaces where your family spends time. Natural repellents offer several benefits:

• Safer around children and pets
• Better for pollinators and beneficial insects
• Less environmental impact
• Affordable and easy to make
• Pleasant-smelling alternatives to harsh chemicals

*While DIY repellents won’t eliminate an established nest or infestation, they can help discourage pests from settling near your outdoor living spaces.*

DIY Wasp and Hornet Repellent Spray Wasps and hornets dislike certain strong scents, making essential oils a useful deterrent. Mix all ingredients in a spray bottle and shake well before each use.

Ingredients:

• 2 cups water
• 1 tablespoon dish soap
• 15 drops peppermint essential oil
• 15 drops clove essential oil
• 15 drops lemongrass essential oil

Where to Use:

• Porch railings
• Patio furniture
• Deck posts
• Around door frames
• Under eaves (away from active nests)
• Reapply every few days or after rain.

Citrus Peel Repellent Many flying insects dislike the oils found in citrus fruits. Rub fresh lemon, lime, or orange peels along:

• Outdoor tables
• Railings
• Window sills
• Patio furniture arms

*You can also simmer citrus peels in water and use the cooled liquid as a natural spray.

Coffee Grounds for Wasps and Hornets One surprisingly popular DIY solution is burning used coffee grounds. Place dry coffee grounds in a heat-safe dish, then:

• Carefully light them until they smolder.
• Allow the smoke to drift through outdoor seating areas.
• Many homeowners report that the scent and smoke help drive away wasps, hornets, and mosquitoes.
• Always monitor any smoldering material and keep it away from combustible surfaces.

Natural Mosquito Repellent Spray Mosquitoes can quickly ruin a summer evening outdoors. Spray around: Patio cushions, deck railings, outdoor umbrellas, seating areas *Avoid spraying directly on plants that may attract pollinators.

Ingredients:

• 2 cups water
• 20 drops citronella oil
• 10 drops eucalyptus oil
• 10 drops lavender oil

Keep Ants Away with Vinegar Ants frequently invade patios, porches, and outdoor dining spaces. Mix: Equal parts white vinegar and water.

Spray along:

• Entry points
• Cracks
• Patio edges
• Walkways

The vinegar scent disrupts ant scent trails and helps deter future activity.

Use Herbs as Natural Pest Barriers Some plants naturally repel common summer pests while adding beauty to your outdoor spaces.

Consider planting:

• Mint
• Basil
• Rosemary
• Lavender
• Citronella grass
• Marigolds

Place potted herbs near seating areas, doorways, and outdoor dining spaces for added protection.

Eliminate Standing Water Even the best mosquito repellent won’t help much if mosquitoes have a place to breed. Mosquitoes can breed in surprisingly small amounts of standing water. Check regularly for: Birdbaths, flower pot saucers, children’s toys, gutters, buckets and tarps.

Maintain Your Outdoor Spaces Pests are more likely to establish themselves when outdoor areas are neglected.

Regularly:

• Sweep away food crumbs
• Clean spills promptly
• Keep trash bins sealed
• Trim shrubs and overgrown vegetation
• Inspect eaves and overhangs for new nests

Know When DIY Isn’t Enough

Natural repellents are excellent preventative tools, but they aren’t a substitute for professional removal when dealing with established wasp or hornet nests, large infestations, or pests that pose a safety risk.

If you discover an active nest near entrances, play areas, or frequently used outdoor spaces, it’s often safest to contact a licensed pest control professional.
