Signs of Outdoor Fly Infestations Swarms or higher numbers of flies: Swarms will occur near a significant food source or potential nest. Maggots: Female flies lay their eggs in garbage cans, rotting food, and manure. Favorite spots include food on outdoor tables, trash bins, compost piles, and pet waste.
In general, flies swarm to wet organic material, ranging from what you're cooking on the barbecue to an unsealed garbage can. Other attractors include animal droppings and wet spots in your yard from heavy rain.
Decay or organic matter: Flies are attracted to decaying organic matter, such as animal feces, compost piles, or rotting vegetation. If you have any of these in or near your yard, they could be contributing to the fly population.
The quickest reasons tend to be: Flies breeding on improperly stored food or in open garbage that hasn't been taken out. Flies coming in as eggs or larvae in new houseplants and then emerging. Flies discovering open windows or doors that allow them easy access indoors.
Flies are typically associated with decay, filth, and disease, which can lead to interpretations of spiritual impurity or moral decay. In many religious traditions, the presence of flies or similar pests may be seen as a negative omen or a sign of neglect, both physically and spiritually. For example:
Exodus 8:21-23
For if you will not let my people go, I will send swarms of flies on you, your officials, and your people, and into your houses; and the houses of the Egyptians shall be filled with swarms of flies; so also the land where they live.
How did I get house flies? House flies are one of the most common insects on the planet. They breed and feed in filth, including garbage, feces, and rotting or spoiled food. Poor sanitation and ripped screens and unsealed cracks in windows and doors can lead to house fly infestations.
Decaying matter is one of the most common causes of a fly infestation in and around your home. As mentioned previously, flies are scavengers and eat dead and dying matter. When flies find decaying matter, they move in to consume them.
Cinnamon – use cinnamon as an air freshner, as flies hate the smell! Lavender, eucalyptus, peppermint and lemongrass essential oils – Not only will spraying these oils around the house create a beautiful aroma, but they will also deter those pesky flies too.
Flies get inside for a number of reasons, usually in pursuit of trash, rotting food, or moisture. A common house fly is attracted to decaying organic matter like feces and rotting meat. Drain flies, on the other hand, are attracted to moisture and will lay their eggs inside of drains.
Mix one cup of water and one teaspoon of cayenne pepper in a misting bottle and spray it near entryways and wherever you see flies. Other natural fly repellents include lemongrass, peppermint, eucalyptus, camphor, and cinnamon.
Flies are attracted to standing water around your property. Remove buckets or birdbaths that hold stagnant water after rainfall and check for debris that holds hidden puddles. Getting rid of these water sources can keep flies from multiplying.
Dirt, waste, and food scraps are all top attractions that will bring flies to your yard. To limit this, keep your patio and garden areas clean and tidy, and ensure all trash and food waste bins are well-sealed.
Choose from either chemical sprays, household cleaners, or hairspray. Chemical sprays kill flies instantly upon contact, though they contain harsh chemicals. You can also spray the flies with household cleaners, like Windex or Formula 409, or with an aerosol like hairspray. All of these sprays will help you kill a fly.
Create a fly and wasp repellent.
This DIY pest repellant should be a staple in the Southern home. Pour equal parts water and Pine-Sol in a spray bottle to spritz on outdoor furniture, the deck, and indoor areas where flies are most likely to flock, such as kitchen countertops.

Both positive and negative spiritual meanings
As we've seen, although flies are associated with filth, disease and death, they are also connected to more positive concepts such as transformation, change and adaptability.
Flies can emerge from several sources including food that's been left out, garbage that needs to be taken to the curb, windows or doors left open, and even as larvae in new houseplants. Drains are a common culprit, too, if water is rarely turned on in a sink or shower.
For example, human semen, particularly dried semen, happens to be a favorite of flies. If enough is made available, they will eat it until it kills them. Blood, although considered a viable source of food, is less desirable, but it can still easily be transferred to a crime scene through fly fecal matter or vomit.
Indoor warmth or unseasonably warm weather can interrupt their hibernation, causing hidden cluster flies to suddenly become active. This usually leads to homeowners noticing insects flying toward windows and light sources during warm winter days.
In addition to making your house smell minty fresh, herbs like spearmint and peppermint can also keep flies at bay. Mint grows quickly and makes an excellent addition to your backyard garden or your windowsill. For those who lack a green thumb, spearmint or peppermint essential oils can also prevent fly infestations.
Flies do not have actual nests. Nests are for social insects, like ants, bees, and termites. The adults take care of the larvae, and feed them, working together. Semi-social insects like earwigs have nests where a single mother takes care of her eggs and nymphs until they can leave and take care of themselves.
