Yes, Lysol does kill roaches! It does this by suffocating them. Roaches breathe through openings on their back called spiracles. The Lysol penetrates the spiracles, causing them to choke and die.
After spraying the roach with Lysol, allow it to sit for a few minutes until it is dead. This should only take a few minutes, as Lysol can kill roaches almost instantly.
Lysol is a disinfectant that contains active ingredients such as ethanol, or ethyl alcohol, and isopropyl alcohol, both of which are proven to be toxic to bed bugs. When sprayed directly on these pests, Lysol will kill them immediately.
Soapy Water: Surprisingly, dousing a cockroach in soapy water will suffocate and kill it. Filling a spray bottle with dish soap and water, shaking it, and spraying a roach from above will kill it quickly. Traps: Most cockroach traps will kill cockroaches quickly.
Lysol can effectively destroy roaches' eggs within a few applications. Since the spray has a high concentration of alcohol, it kills eggs the same way as cockroaches. It dissolves and dries the outer layer of the eggs, destroying them even before they hatch.
But let's say you've already found an egg case or two under your sink. In that scenario, you can buy what are called desiccant dusts—like diatomaceous earth, a non-toxic substance you can find on Amazon—and that will dehydrate the eggs, thereby killing them.
Soap and water are a good start, but you can also use baking soda to help get rid of the roach smell. Another option is to use a disinfectant cleaner to wipe down surfaces. Make sure you clean floors, appliances, counter tops, cabinets, and anywhere else you have seen signs of roaches.
Aerosol sprays: Aerosol sprays are a type of insecticide that comes in a pressurized can. They are designed to kill cockroaches on contact and can be sprayed directly onto the insect. Aerosol sprays can be purchased at most hardware or grocery stores and are an effective way to kill cockroaches instantly.
Boric acid: Used correctly, boric acid is one of the most effective roach killers. It's odorless, has low toxicity to pets, and since it isn't repellent to roaches, they will not seek to avoid it, crawling through it repeatedly until it kills them.
Citrus. You may love the smell of fresh citrus, but cockroaches hate the scent. That means you can use citrus scented cleaners in your kitchen and bathroom to chase any lingering roaches away. You can also keep a few citrus peels around your home in strategic places.
That being said, if you only have the occasional cockroach, then Lysol might be enough to take care of your small infestation. Because Lysol has weaking killing power, but Lysol's smell can repel roaches, it might be enough!

Expect An Influx of Roaches
You can use a vacuum cleaner to clean up the ones you see, but you don't need to use any chemicals. Expect to see them for up to two weeks after the roach spraying treatment.
To help keep these trouble areas roach free, spray them weekly for basic prevention and every 3-4 days if you're currently experiencing a heavy roach problem. If after two weeks, you're not seeing the results you want, simply adjust to a more frequent spraying schedule. Don't forget to spray and seal entry points.
If you leave the spray and let it dry, it will keep killing cockroaches with residual action for up to 2 weeks as long as the bugs come in contact with it.
Sprinkle boric acid in areas the roaches frequent; when they walk through it, it sticks to them. They later ingest the boric acid, which then kills them. When using boric acid, be sure to limit your exposure; don't place it anywhere that children or pets might find it, as it's toxic when ingested.
Gel baits: According to Black, gel baits are the best roach killer option. These are available as either plastic bait stations or gel formulations that come in plastic syringes. The baits contain insecticide-laced foods that cockroaches eat.
Spraying window cleaner directly onto small insects like ants or mosquitoes will kill them within a few moments. For cockroaches, window cleaner can make them temporarily unconscious so that you can squash them. This works on initial contact, but Windex will not continue to kill bugs after it has dried.
Unfortunately, bleach is a very ineffective method for killing cockroaches. It has a very strong smell, so it doesn't work as bait, and cockroaches won't willingly go to it. The only real way to kill a roach with bleach is to drown it, and there are much more effective ways of killing cockroaches.
Windex can kill cockroaches, but only if you twist the nozzle to stream mode and spray it directly, full-strength on a single insect for at least a minute. We give it a 3/10 on our effectiveness scale.
Cockroaches are attracted to the food and shelter that comes with filth. Cleaning your home is the easiest way to keep roaches at bay. You need to be incredibly thorough in this effort—unfortunately, roaches can survive for 2 weeks without water and 3 months without food.
To get rid of cockroaches, you must take away their:
Rinse all recyclables clean and take them out every few days. Put garbage in tightly covered containers and keep them outside. Wash dishes, tables, counters and stove tops every day.
Some factors that can attract cockroaches to clean houses include: Moisture. Leaking sinks and appliances create conditions in which roaches thrive, since they offer a readily available source of water as well as the warm, sheltered spaces that provide the ideal harborage for cockroach nests. Untidy landscaping.
