One cockroach in the kitchen can be enough to make you check every corner before bed—especially if you see it again a couple of days later or spot smaller ones. The obvious questions are: Where did they get in? Is cleaning enough, or is the problem bigger?
The reassuring news is that dealing with cockroaches starts with simple steps: identify where they appear, remove access to food and water, and reduce places where they can enter or hide. Traps or cockroach baits may help when used according to the label. But getting rid of them “for good” depends on finding and addressing the source. If they keep returning or show up in more than one room, you may need a specialist to inspect the property for cockroaches in Riyadh.
Not all cockroaches look alike. Identifying the type can help you know where to look, though a specialist may be needed to confirm it:
- German cockroach: Small and light brown, usually with two dark stripes behind the head. Often found in kitchens and bathrooms near heat, moisture, and food.
- American cockroach: Larger and reddish brown. It may enter through drains or gaps around pipes and sometimes appears near utility rooms or damp areas.
- Oriental cockroach: Dark and shiny, and tends to favor cool, damp places such as basements and drainage areas.
The types found in a home can vary depending on the building and how insects get in. If you’re unsure, a clear photo taken from a safe distance may help a specialist identify the cockroach.
Sometimes cockroaches disappear before you can get a good look, but they leave signs behind: small dark specks, brown egg cases near cracks or behind appliances, or repeated activity inside cupboards and around the sink. An unpleasant smell may appear if there are many of them. Seeing one cockroach once isn’t enough to determine the scale of the problem, but repeated sightings or signs of activity deserve attention.
Cockroaches may enter or move through a building by way of:
- Gaps around water pipes, drains, and cables.
- Cracks and gaps around doors, windows, and cupboards.
- Drains and shared utility areas in apartment buildings.
- Cardboard boxes, bags, appliances, or furniture brought into the home.
If you live in an apartment and see cockroaches near pipes or in more than one unit, they may be coming from a shared area of the building. Letting building management know can help address the source instead of allowing the problem to move back and forth between apartments.
It’s frustrating to spray and then see cockroaches again later, but that doesn’t necessarily mean the pesticide “didn’t work.” They may be hiding in cracks the spray didn’t reach, finding food and water easily, or entering through an unsealed gap. A product may also be less effective if it isn’t suitable or wasn’t used as directed. Spraying alone doesn’t always address the underlying problem.
Start by figuring out where the cockroaches appear. Then reduce what attracts them and seal entry points where possible. If you use a product, follow its label. Don’t mix pesticides or spray over bait on your own; ask a specialist if you’re unsure.
A few simple steps can make a difference: clean up crumbs and grease, store food in airtight containers, keep the rubbish bin closed, fix leaks, and dry the sink before bed. Reduce cardboard and clutter where possible. Sticky traps can help you identify areas with more activity and track numbers, but they may not be enough on their own if the infestation is widespread.
Ready-to-use baits may help with limited infestations, provided they’re registered, intended for cockroaches, and used according to the instructions. Place them only in permitted locations, away from food, exposed surfaces, and the reach of children and pets. Don’t use more than directed in hopes of getting faster results, and don’t repeat the application unless the label recommends it.
As for home remedies: vinegar, salt, and strong-smelling substances aren’t proven substitutes for treating an existing infestation. “Natural” and “odorless” don’t mean a product is risk-free. Boric acid can be harmful if swallowed or if its dust is inhaled, so keep it out of reach of children and pets and follow the label.
In Saudi Arabia, the Saudi Food and Drug Authority recommends checking the pesticide name and registration number against its list of public health pesticides, and following the label’s instructions and warnings. Check the pesticide’s registration with the Authority and follow its pesticide safety guidance.
- Start by observing: At night, check around the sink, refrigerator, oven, and inside cupboards. Write down where you see cockroaches.
- Remove food sources: Clean up crumbs and grease, wash dishes, and clean behind appliances when it’s safe to do so.
- Reduce moisture: Fix leaks, dry damp surfaces, and don’t leave standing water in the sink.
- Track activity with traps: Place traps along walls near areas of activity, where children and pets can’t reach them. Record how many you catch and where; this can help you tell whether the situation is improving.
- Use products carefully: If you choose a bait or household pesticide, check that it’s registered and suitable for indoor use, and follow its label. Don’t mix products.
- Seal entry points: Close cracks and gaps around pipes and doors with suitable materials. Don’t block ventilation openings or drains that are in use.
- Know when to get help: If cockroaches continue to appear or start showing up in new places despite cleaning and reducing food and water sources, a specialist inspection may save you from repeated trial and error.
When is it best to call a pest control company? If you see cockroaches regularly or in more than one room, they return after treatment, or you can’t work out where they’re entering. The same applies if they’re near pipes or shared areas of the building. Restaurants and food preparation areas need a carefully planned treatment suited to the space. If you have an infant, someone with asthma or allergies, or pets, tell the company from the outset so it can explain the relevant precautions.
Before booking, you have the right to ask how the inspection will be carried out, which product will be used and its registration number, where it will be applied, and what you’ll need to do regarding evacuation and ventilation. Also ask whether a follow-up visit is included. A good company will explain the plan clearly and first investigate the source of the problem instead of making a quick promise to eliminate it.
- Store dry foods in airtight containers and don’t leave food uncovered.
- Empty the rubbish bin regularly and keep it closed.
- Wash dishes and clean up food scraps and grease promptly.
- Dry the sink and repair water leaks.
- Clean behind the refrigerator and oven regularly, disconnecting appliances safely when needed.
- Check boxes and bags before bringing them into the home, and get rid of unnecessary cardboard.
- Seal gaps around pipes and doors. If the problem keeps returning, ask building management to inspect shared areas.
Do cockroaches fly? Not necessarily. Some larger types can fly or glide short distances, but their ability to fly doesn’t by itself mean they’re more dangerous. The priority is to keep them away from food and surfaces and, if they keep appearing, identify where they’re getting in.
How long does treatment take? There’s no set timeframe that applies to every home. Results depend on the cockroach type, the size and source of the infestation, and the treatment method. Some cases need follow-up. Follow the product instructions or the company’s treatment plan, and contact them if activity continues.
Is boric acid safe to use? Don’t assume it’s safe just because it’s commonly used. It can be harmful if swallowed or inhaled, so keep it completely out of reach of children and pets and follow the label. If you have young children, ask a specialist about treatment options that reduce the chance of their exposure to pesticides.
If you’ve tried preventive steps and the cockroaches keep coming back, you don’t have to keep trying one product after another. The Onyx team can inspect the property, identify the type and entry point, and explain treatment options, safety precautions, and follow-up before starting.
