ALL ABOUT COCKROACHES
What attracts cockroaches?
Cockroaches, also known as cockroaches, are attracted to a variety of factors in a home. Here’s what may attract them:
- Food: Cockroaches are omnivorous and will eat just about anything, including food scraps, crumbs, and even inedible foods like paper or glue. It is therefore important not to leave food out in the open and to clean it regularly.
- Water: Cockroaches need water to survive, so any source of water, such as a leaky sink or standing water, can attract them.
- Heat and humidity: Cockroaches prefer warm and humid places. Bathrooms, kitchens and basements are often their favourite places.
- Shelter: Cockroaches look for dark, hidden places where they can breed safely. Cracks and crevices in walls, cabinets and appliances are perfect places for them.
- Clutter: A cluttered environment can provide many places for cockroaches to hide and find food. A clean and tidy home can help prevent a cockroach infestation.
By understanding what attracts cockroaches, you can take steps to make your home less attractive to them and help prevent an infestation.
How do we know if we have cockroaches?
There are several signs that may indicate the presence of cockroaches in your home. Here are some of the most common signs:
- Cockroach sightings: If you see a cockroach during the day, it is likely that there are many more, as they are primarily nocturnal.
- Cockroach droppings: Cockroaches leave behind droppings that look like peppercorns or mouse droppings. You can find them in places like kitchen cupboards, drawers, and behind appliances.
- Oothecae: Cockroaches lay their eggs in what is called oothecae, which are elongated egg sacs. If you find any, it is a sure sign that you have a cockroach infestation.
- Odour: Cockroach infestations can produce a distinct odour, often sweet and unpleasant.
- Dead cockroaches: You may find dead cockroaches in places like basements, damp areas or near water pipes.
- Damage: Cockroaches can damage a variety of items in your home, including books, curtains, wallpaper and food.
If you suspect a cockroach infestation, it’s best to call a exterminator professional to help you eliminate them effectively.
How to get rid of cockroaches?
Getting rid of cockroaches can be a challenge, but there are several methods you can use:
- Cleaning: Cockroaches are attracted to dirt and food. So keep your home clean, especially the kitchen and bathroom. Eliminate all sources of food and water.
- Pest control products: Use cockroach traps, bait gels and insecticide sprays. These products can be effective, but they must be used correctly. Follow the instructions on the product label.
- Professional services: If the infestation is large or difficult to control, it may be necessary to call in a professional exterminator. Professionals have access to more powerful treatments and can ensure that the entire colony is eliminated.
- Prevention: Once you have eliminated the cockroaches, take steps to prevent re-infestation. Seal cracks and holes where cockroaches can enter your home, and continue to keep your home clean.
Remember, it is always easier to prevent an infestation than to control it once it has taken hold.
Is it serious to have cockroaches?
The appearance of cockroaches in a home is never a desirable situation. There are several reasons why their presence may be of concern:
- Hygiene: Cockroaches are known to carry pathogens, including bacteria and viruses, that can cause disease in humans. They can also cause allergies or asthma in some people.
- Rapid multiplication: Cockroaches reproduce very quickly. A small infestation can become a major problem in a concise time if not treated quickly.
- Nuisance: Beyond health considerations, the simple presence of cockroaches can be disturbing and stressful for the occupants of a home.
- The difficulty of eradication: Cockroaches are resilient insects that can survive in difficult conditions. They can be difficult to eradicate without professional help.
It is therefore important to take the presence of cockroaches in a home seriously and act quickly to eliminate them. If you suspect an infestation, it is recommended that you call a professional exterminator.
How do you know if you have a cockroach nest in your home?
Detecting the presence of a cockroach nest in your home can be difficult, but here are some signs that might indicate their presence:
- Cockroach activity: If you see roaches moving around during the day, it could be a sign of a large infestation. Cockroaches are generally nocturnal and prefer to hide during the day. If you see them during the day, it’s probably because there are so many roaches that they are forced out.
- Cockroach droppings: Cockroaches leave small black or brown spots similar to acceptable peppercorns or coffee grounds. If you find these marks in hidden areas, such as behind furniture or appliances, it may indicate the presence of a nest.
- Odour: Heavy cockroach infestations may produce a distinct odour. Some describe it as a sweet, rancid smell. If you notice such an odour in your home, it could be a sign of a cockroach nest.
- Cockroach eggshells: Cockroaches leave their eggs in shells or capsules called oothecae. These shells are generally of light brown colour and have an elongated shape. The discovery of these shells may be a sign of a cockroach nest.
If you notice any of these signs, it is recommended that you call in a professional to inspect your home and remove the roaches.

COCKROACHES: FACTS AND INFORMATION
A few dozen eggs are grouped in two rows inside a protective capsule. This shell with rigid walls is called an ootheca. At first whitish, the ootheca turns then to brown, and it produces most often four or five, which contain about thirty embryos or more.
Young cockroaches are quick to seek out food. Depending on the species, the larvae undergo between four and fifteen molts before becoming adults, sometimes with an additional molt for the female (the German cockroach undergoes six or seven molts and the American cockroach a dozen).
Cockroaches that live in homes can lay eggs throughout the year. The life span of adults and the life cycle vary according to the species and environmental conditions, in particular temperature. For example, the German cockroach can live for over 200 days. It spends about 23 days as an egg and 27 to 103 days in the larval stage. Its life cycle can be completed in about 60 days at 27°C and 40% humidity. The insect produces typically three or four generations per year.
Domestic species inhabit homes, warehouses, businesses and any other heated building in winter where they find sufficient moisture and food. Warm and humid places such as bathrooms are ideal for cockroaches to invade Quebec.
In our homes, they feed on fruits, vegetables, meat, pet food, cheese, pasta, cereals and cookies, leather, fabric, hair and glue (on the wallpaper, book bindings and stamps), and all other food sources.
In Quebec, most cockroaches living in homes are active at night and avoid light. They usually remain motionless during the day, leaving their shelter in the evening to search for food. Seeing cockroaches activate in the daylight is a sign that the population is very high.
The bad reputation of cockroaches is largely due to the fact that they transmit an unpleasant odour and taste to the food products they feed on. They also soil the food with their excrement. When infested severely, these insects leave a musty smell on objects and cause a health hazard.
Cockroaches are among the most unpleasant household insects. They leave a bad smell and contaminate food with their secretions and excretions. In addition to food, they can damage books and paper, causing havoc in libraries and have a strong ability to adapt.
The German cockroach is by far the most common species found in our homes. The following recommendations apply to the cockroach but are also valid for other domestic cockroaches. There are, however, some peculiarities depending on the species, so identification of the insects to be eliminated can be useful. The brown-banded cockroach, for example, is more tolerant of low humidity than other cockroaches and can settle in warm, very dry places (behind radios, televisions and other heat-emitting devices).
