As the summer season approaches, many people look forward to spending time outdoors, enjoying the warm weather. However, with the rise in temperature comes the increase in pesky insects like flies. Flies can be more than just a nuisance; they can also carry diseases and create an uncomfortable environment in your home. In this comprehensive guide, we’ll explore effective strategies to keep flies out of your house in summer.


Keeping flies out of your house in summer involves several strategies. First, install fly screens on windows and doors to prevent flies from entering. Use natural repellents such as certain plants and essential oils, and maintain cleanliness by disposing of garbage promptly and keeping food in sealed containers. Seal gaps and repair screens to ensure flies cannot enter through small holes. Commercial fly repellents can also be used for added protection.

Understanding Flies

Before we delve into the solutions, it’s crucial to understand what attracts flies. Flies are attracted to light, warmth, and odors, especially those coming from food and garbage. They are also attracted to moisture and will often breed in damp, organic material.

Effective Techniques to Prevent Flies

Install Fly Screens

One of the most effective ways to prevent flies from entering your house is by installing fly screens on windows and doors. These screens block flies from entering while still allowing fresh air to circulate in your home.

Use Natural Fly Repellents

Certain scents and plants can repel flies. Plants such as basil, lavender, mint, marigold, bay leaves, and catnip are known to deter flies. Place these plants near windows and doors or use their essential oils to create a natural fly repellent spray.

Maintain Cleanliness

Flies are attracted to food waste and dirty areas. Regularly cleaning your kitchen, disposing of garbage, and storing food in sealed containers can minimize fly attraction. Also, avoid leaving dirty dishes or glasses out on the counter.

Seal Gaps and Repair Screens

Flies can enter your home through small gaps and holes. Ensure all windows, doors, and vents are sealed properly and free from holes or other damage.

Natural Remedies to Keep Flies Away

Plants and Herbs

Flies are deterred by certain plants and herbs. Basil, lavender, mint, rosemary, and lemon balm are some of the plants known for their fly-repelling properties. You can grow these plants both indoors and outdoors.

Essential Oils

Flies dislike the smell of certain essential oils, such as lavender, eucalyptus, peppermint, lemongrass, tea tree, and citronella. You can create a spray by mixing a few drops of your chosen essential oil with water or a carrier oil and spraying it around your house.

DIY Fly Repellent Spray

A homemade fly repellent spray can be made by mixing 1 cup of water, 1 tablespoon of vinegar, and a few drops of dish soap in a spray bottle. Spray this mixture around your home to deter flies.

Commercial Fly Repellents

There are several types of commercial fly repellents available in the market. UV light fly traps, fly sticks, insecticide concentrates, pressurized fly baits, electric insect killers, and glue traps are some of the most effective fly control products. Always follow the product’s label directions and safety precautions when using fly repellents.

Common Mistakes That Attract Flies

Avoiding common mistakes can significantly reduce the likelihood of attracting flies into your home. These mistakes include ignoring the root cause, maintaining clutter, leaving food uncovered, and poor waste management.

Preparing Your Home for Summer

Before the summer season begins, homeowners can take several steps to prevent fly infestations. Maintaining cleanliness, proper waste management, sealing entry points, installing screens, eliminating standing water, and using natural repellents can effectively prepare your homes for the summer season.


Keeping flies out of your house in summer may seem like a daunting task, but with these tips and strategies, you can enjoy a fly-free summer. Remember, prevention is better than cure.
