New cockroach behavior discovered by University of California, Berkeley, biologists secures the insect's reputation as one of nature's top escape artists, able to skitter away and disappear from sight before any human can swat it.
Roaches cannot come back to life but can play dead convincingly. If exposed to deadly circumstances, roaches may go into shock and remain immobile until they can move again. If you think you've killed a cockroach, but it begins to move a short time after, it was never really dead in the first place.
It is normal for roaches to come out once they spray and for two weeks, you will see lots of them but don't be afraid. It is typical to see them wandering around since they have been sprayed so they will look for food sources or water for them to thrive.
Once the problem is under control and you do not see any more roaches, it is recommended to spray something once every 30 to 60 days inside and outside your home to help keep the problem from coming back.

Baby roaches – in kitchens or bathrooms – are usually an indication of a German cockroach infestation. These roaches are commonly found in kitchen and bathroom areas because they offer a warm, humid environment with plenty of moisture and access to food.
The most common places for a roach nest in the house are in kitchens or bathrooms, particularly behind refrigerators, in cracks and crevices, and under furniture.

The myth that killing a cockroach will spread its eggs isn't true, but killing a cockroach with force can attract more. But that can be used to your advantage if it brings bugs out of hiding to be eliminated.

Do baby cockroaches jump? No. Many species of baby roach can move quickly, but their legs are not made for jumping.
Cockroaches are social insects and often live in family groups. They have unusual reproduction: females lay eggs in groups of 4-30 bundled together.

Most cockroach species aren't good "flyers," and what you take as them flying toward you is actually just them being startled and gliding uncontrollably in a certain direction.
Generally, young cockroaches prefer to stay in out-of-reach areas near the place where they hatched. They don't spread out far looking for food or another place to live if they can avoid it. If you see baby cockroaches in your home, there is probably an existing infestation of adult roaches.

Life cycle of cockroaches
Adults lay eggs contained within dark-colored egg cases (size and shape of a dry kidney bean). Depending on the species, an egg case contains between 16 - 50 eggs. Eggs hatch into young cockroaches called nymphs, that are more numerous than adults.
