Roaches lay their eggs in any safe place that is damp or hidden. They like to be close to food while still being far enough away from human reach. American roach eggs: Female American cockroaches glue their oothecae to hard surfaces, like your cupboards, or cardboard near a food source.
Cockroaches prefer nesting in areas that are more likely to absorb their strong odor — places where you store paper, cardboard or wood. Thus, if you store your clothes in a wooden dresser, cockroaches will be more likely to lay eggs in your clothes.
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. Roaches prefer a warm, humid environment, so these places should be considered first, especially if they are close to a food source and water supply.
Their nests can often be found near plumbing fixtures in bathrooms and kitchens, in cupboard cracks or under drawers, inside appliances or underneath the fridge. You may also notice cockroach droppings around the nest's location or your nose will help you sniff it out — most have a strong, foul odour.
What's worse is that cockroaches can lay eggs in and on your furniture. Help prevent this by regularly vacuuming upholstered furnishings and inspecting wooden furniture for egg casings that need to be cleared away.

Your best bet for finding roach eggs is to look near things that adult cockroaches like, such as food, water, and cardboard. Check for them in kitchens where there is plenty of food and water. And bathrooms where drips and condensation make water easy to find.
While cockroaches are one of the most common pest problems, they are also one of the most stubborn. Infestations are hard to get rid of because the insects hide in a host of areas, breed quickly, have a very high reproductive potential and may develop resistance to pesticides.
Breadcrumbs or baby food can be effective lures to draw cockroaches out of their nests and into your traps. You can also use peanut butter – and dipping pieces of bread in beer has also been shown to be an especially enticing lure for cockroaches.
You may be wondering: "I saw one cockroach, should I be worried?" If you spot even one roach during the daytime, it can mean the infestation has been going on for some time or that it has progressed to the point where drastic action must be taken immediately.
Roach Repellents
Peppermint oil, cedarwood oil, and cypress oil are essential oils that effectively keep cockroaches at bay. Additionally, these insects hate the smell of crushed bay leaves and steer clear of coffee grounds. If you want to try a natural way to kill them, combine powdered sugar and boric acid.
Boric acid is a powerful natural home remedy for getting rid of roaches overnight. Mix equal amounts of boric acid, flour, and sugar until it becomes a dough-like consistency. Place small pieces where the roaches can feed on them.
The Australian cockroaches (Periplaneta australasiae) are quite similar to American cockroaches - except their body is smaller and darker. Their eggs are about 9 mm in length and are reddish-brown in colour. A female Australian cockroach can produce about 22 - 24 eggs in a single ootheca during her lifetime.
With around 12 young in every egg case, a female and her offspring can produce 800 additional cockroaches in just a single year.
We've recently heard a rumor that squishing a cockroach is a bad idea because it could spread the insect's eggs around, making more baby cockroaches. "The crushing in itself doesn't really spread eggs," said Louis Sorkin, a scientist in the entomology department at the American Museum of Natural History.
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.
Once a roach has found and consumed bait, it typically dies within 1-3 days. A substantial reduction in the infestation overall should be apparent within a few weeks. With cockroach baits, it usually is not necessary to empty kitchen cabinets or cover food preparation surfaces before treatment.
Scents that are pleasing to humans can actually repel cockroaches. In the kitchen, certain aromas such as cinnamon, bay leaves, garlic, peppermint, and coffee grounds can be used as deterrents. In the bathroom and garage, using strong-smelling disinfectants like vinegar or bleach can help keep these pests at bay.
Cockroaches seek places where they can find ample food. Food crumbs, spills, leftovers, and pet food are the most common food sources. Kitchen trash and grease on stovetops and countertops can be inviting for roaches, and they may also get into stored food items.
The best way to get rid of roaches fast is to sanitize your home, eliminate hiding spots and stagnant water, store food in airtight containers, and use glue strips, bait, boric acid, or liquid concentrates.
It's instinctive: you see a cockroach and you crush it. Or you run away. However, entomologists advise against doing the former, because cockroaches can support 900 times their weight. Lightly stepping on the insect or swatting it with a newspaper is not the best plan.
You'll know you've found a pregnant roach if it appears to have a pill-shaped protrusion sticking out like a fat, ribbed tail. This extends further as more eggs develop inside it. The “pregnant” female carries her egg case for about 1 month until the eggs are ready to hatch.
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.
Here are some tips on how to identify roach eggs: Look for small, white, cylindrical eggs that are about 1/8 of an inch long. Eggs are often found in clusters and can be hidden anywhere from cracks and crevices in the wall to inside furniture. Eggs are usually found in a protective casing called an ootheca.
