How do I get rid of flies outside of my house?
Similarly one may ask, why are there flies all over the outside of my house?
Outside-breeding sites: House Flies may be found feeding and breeding in fresh manure, rotting fruits and vegetables, garbage, damp garbage, and decaying organic materials that are located outside of the structure. Most of the time, when you find house flies inside, it is because they are coming inside the structures.
Moreover, can you spray for flies outside?
Though aerosol fly sprays will have little to no lasting effect outdoors, they can provide quick knockdown and kill flies on contact, so can be used just prior to picnics and outings. Insecticide fly baits can be put out in small bait stations to attract and kill flies.
If anyone has recently eaten on your porch, this may be the cause of your fly problem. Flies also like food scraps such as rotting meat, so search your porch carefully and dispose of any garbage in a bin with a secure lid. Strong odors attract flies, so even unopened food can cause them to swarm your porch.
