Indoor Cockroach Predators Inside, cockroaches typically die of old age. However, their remains feed a number of hungry creatures, resulting in yet more pest problems for residents. Beetle larvae,
Insects and Arachnids
Strangely enough, one of the most prevalent kind of predator that cockroaches face are fellow insects! The emerald cockroach wasp, Ampulex compressa, for example, has an unusual way of preying upon cockroaches. The wasp stings the cockroach's brain, which paralyzes the cockroach.
Toads, mice, and shrews are their main natural predators. Some spiders and parasitic wasps have also been known to prey on them.
Spread of Eggs
The number one reason to not squash a cockroach is to prevent spreading cockroach eggs. Some cockroach species, such as the German cockroach (common species here in the UK) carry their egg cases (ootheca) on their body until just before they hatch.
Baking soda is a fast and effective way to kill roaches. When a roach ingests baking soda, the baking soda expands inside them, causing the roach to explode. Simply sprinkle baking soda on food, such as an onion, and leave it near where you've seen roaches overnight.
Some strong scents, such as lavender and mint, have been known to repel cockroaches.
Good old-fashioned soap and water is a safe, reliable, and inexpensive method. Create a soapy water solution that you can spray with a bottle. It will only take about 2 – 3 sprays to kill any roaches, as the soapy solution will cover their breathing pores and suffocate them.
Citronella Oil
Its strong scent is known to deter roaches and other insects like mosquitoes and gnats. Homeowners can either directly apply the oil to areas frequented by roaches for the most effective application or dilute it with water to create a DIY repellent spray.
Center of gravity: Cockroaches have a high center of gravity and a rounded back, which makes them prone to tipping over. Once a cockroach is upside down, it struggles to gain traction on flat surfaces, making it hard to flip back over.
Don't panic. There's plenty you can do to get the issue under control. Start by cleaning up any food residue or spillages, and don't leave mess lying around. Check for signs like cockroach droppings and set up sticky traps until the pest experts arrive.
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.
Toads, frogs and lizards can reach out to roaches with their long, sticky tongues and crush them in their strong jaws. Wasps, on the other hand, will often lay their eggs within adult cockroaches and larvae.
Citrus is one of the scents cockroaches are most known to hate, notably lemon and orange. Keeping a dish of lemon juice on your kitchen counter can deter these pests, as well as placing lemon peels around the home to discourage cockroaches from coming out of hiding.

Boric acid is a stomach poison that is picked up by cockroaches walking across dusted areas. The boric acid adheres to the cockroach cuticle so when the cockroach grooms itself it ingests the boric acid and soon dies.
Attractor #1: Food
What attracts cockroaches more than anything is food. Roaches need food to survive. Eliminating access to food can help eliminate a roach problem. Throw away any food that has been left out on the counter.
Yes, it's dangerous to ingest food after they've crawled over it, so your pantry is at risk. But it's also dangerous to stomp or smash them because the particles can get sent into the air where they can be swallowed or inhaled. And when you retrieve the dead bug your hands can become contaminated.
American cockroach life cycle
A female American roach can produce up to 224 offspring. American cockroaches go through 10 to 13 instars before reaching maturity. Adult males can live up to 362 days, whereas adult females can live more than 700 days.
A cockroach can feel the change in air current and change in the surroundings, and when they encounter us, they look in their surroundings, looks for a place from where they can escape, and then chase you, scare you, and make a run toward the escape. They use this strategy against many other predators.
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.
DIY spray: Spray the solution in areas prone to cockroach infestation, such as kitchen cabinets, under sinks and around appliances. Apply every few days for the best results.
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.
Rosemary is considered one of the best roach repellents because it's actually highly toxic to the insects. Even better, this plant can be found at your local nursery, hardware store, or plant shop and requires little water. Just make sure you place it in direct sunlight.
