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.
The perimeter spray is designed to last approximately 30 to 90 days in terms of protection and is generally applied around skirting and kick boards at the walls edge. After treatment, avoid mopping the areas around your skirting or kick boards for several weeks.
Pest control sprays generally take between 2 – 4 hours to dry which is why this is the time that is recommended for inhabitants to stay away. It is not recommended that inhabitants return before pesticides dry because they can cause health problems if touched or breathed in.
Once the spray dries, it typically loses its potency against insects, meaning it won't kill bugs that come into contact with the dried residue. However, some sprays may leave a residual effect that can deter bugs but won't necessarily kill them. For ongoing pest control, it's usually best to reapply as needed.
You can sleep in the room after spraying it if it's a non-residual raid. You're good to go after cleaning up the Raid. If it's a lingering raid, though, you won't be able to sleep in the room once you've finished spraying it with the Raid. You can use Raid to get rid of bed bugs, cockroaches, and other insects.
Give It Some Air!
After applying Raid® spray products such as Raid® Mosquito and Fly Killer, give the treated room or area some air! Exit the treated area and keep the room closed for 15 minutes. Then thoroughly ventilate before re-entry. Read the product label for more detailed instructions.
Around two to three weeks after an extermination visit, it's normal to see handfuls of dead roaches around your home. Because many products won't eliminate the insects on-site, they could perish as they're foraging or looking for water. Don't fret if you see these pests scattered throughout your home.

Droppings are a big sign of roaches. The size depends on the roach species, but you are looking for black or brown droppings that may look like pepper or coffee grounds. If you see feces continuing to accumulate after a pest control treatment, you still have roaches.
Cockroaches are attracted to various factors, including food, water, shelter, and warmth. They are particularly drawn to crumbs, spills, and food residues, especially starchy and sugary items. Moisture-rich environments like leaky pipes and standing water also attract cockroaches.
Key Takeaways. Using a cockroach bomb can unnecessarily expose you and your family to nasty pesticides. It's also likely that a fogger or bug bomb will drive bugs back into hiding, where they may continue to reproduce and cause an infestation.
Cockroaches won't go away on their own.
Generally, the presence of discarded skins and feces are indicative of a nest, with other telltale features including a large number of dead roaches, egg cases, dark spots, and smears. Egg cases are usually brown and less than a quarter of an inch long. Each case can house 40 or more baby roaches.
Leaving the light on doesn't deter cockroaches effectively because they can navigate in low-light conditions. While they're mostly active at night, they may still come out in search of food or water. During the day, cockroaches hide in dark areas not directly exposed to light.
Cockroaches are blessed with an amazing sense of smell. This is what they use when seeking food and mate but at the same time, this is also their weakness. A cockroach's sense of smell can be used to get rid of them.

The scent of cooking oils, sauces, and spices can also attract these pests. Garbage odors, like smell of rotting food and other organic matter, which is often found in garbage cans.

If you see one, there are likely many more that you can't see.

Roaches can reappear after extermination due to their adaptive nature. Continued prevention and maintenance are vital to keeping cockroaches at bay. Recurring infestations might require additional professional treatment and advice.
If you only see baby roaches, it could mean a few things: Recent Hatchings: You might be seeing a recent hatching, and the adults are hiding. Effective Treatments: If you've recently treated your home for roaches, the treatment might have killed many adults, leaving behind only the babies.
