What are some common types of indoor flies?

What are the best indoor fly sprays?
There are two types of indoor fly sprays: aerosol and non-aerosol sprays. Aerosols, which can sometimes contain toxic ingredients that are bad for the environment, deliver propellants in a steady aerosol spray. Non-aerosol ones are typically a bit greener, but require a more direct application and usually have a trigger mechanism of some sort.
Conventional fly sprays contain synthetic chemicals. Most of these are rigorously tested to determine their toxicity to humans and non-insect organisms. These synthetic sprays are effective, but may also leave harmful residues behind. It’s important to read labels to make sure the spray is safe to be used on clothes, bedding, or other surfaces that may be frequently touched.

Are there any environmentally-friendly indoor fly sprays?
There are quite a few green-friendly indoor fly sprays on the market today and many utilize essential oils as their active ingredients. These oils are usually derived from plants like peppermint and wintergreen, sweet-smelling flora that already possess a potent bug repellent within. All of them are just as effective at killing insects as their synthetic counterparts and they’re much better for the environment because they don’t leave a toxic residue. They’re also better for you and your family.

Where is the best place to apply an indoor fly spray?
Almost all indoor fly spray is made to be applied directly to the bugs themselves. But, you can also spray them on windows, doors, screened-in porches, and in any cracks they use to enter, to create a barrier.
You can also spray on countertops in the kitchen and bathroom, or on garbage cans, anywhere that you assume draws the little buggers. If you have an indoor compost bin, spray that as well, as incorrectly built piles will attract flies.

Are indoor fly sprays effective?
Sprays are efficient, but they do come with their own complications. First, many sprays are toxic to pets or children, so finding a non-toxic or even an eco-friendly spray is essential if you have animals or kids in the home.
Second, flies can be widespread, so taking them down with spray means coating all areas of interest, which takes time. Lastly, even the most potent indoor sprays are not a “catch-all solution.” The best way to keep flies out is prevention.
How do I prevent flies in my home to begin with?
The most effective way to get rid of flies is to keep them out in the first place. Seal off all places where you think flies can enter your home. Fix window screens, caulk cracks and crevices, use steel wool in the gaps around pipes or cables, and if there any particularly wide gaps, seal them off with a very fine wire mesh. This will keep other unwanted pests out as well.
Next, eliminate any food sources or potential breeding grounds. Ensure your garbage and compost are covered, and take them out often. Keep the sink empty of dirty dishes and wipe down surfaces often. You can even pour bleach down the drain if you feel the insects are fluttering around your dish drain. Be sure not to overwater plants, as swampy soil can attract gnats. If your backyard has any birdbaths or standing water sources, stagnant water is the perfect place to breed mosquitos.
