In Singapore, getting rid of roaches overnight and preventing their return requires a targeted and effective approach. Start by cleaning every corner of your home so that these insects cannot hide. Wipe down counters, vacuum the floors, and fix any leaky faucets.
Use a combination of instant and long-term solutions to get the best result. Try gel baits or insecticides in high-traffic areas like under sinks, behind appliances, and in cabinets for an instant solution. Boric acid or diatomaceous earth can also work for instant killing.
Baking soda-sugar mix, dish soap spray, ethanol, insecticide, neem, and essential oils will also work. Call professional pest control services for a fast and deep extermination if nothing works due to heavy infestation.
12 Ways to Get Rid Of Roaches Overnight Permanently
1. Boric Acid Powder
Boric acid is an effective solution to kill cockroaches. Research has proven that it works better than sodium tetraborate or disodium octaborate. Cockroaches ingest it when they groom themselves. It will disrupt their digestive and nerve systems and eventually kill them within 6–72 hours. Dust it under refrigerators, cabinets, stoves, and entry points. Avoid piling it.
2. Baking Soda + Sugar Mix
The mixture of baking soda and sugar will work for light infestations. Mix 1 cup of baking soda with 1 cup of sugar and place it in bottle caps or shallow dishes near walls or dark corners. Sugar will attract the cockroaches, and baking soda will react with the stomach acids. It will create gas and kill them instantly.
3. Diatomaceous Earth (Food Grade)
DE is made of fossilized algae with sharp microscopic particles. These cut into a roach’s exoskeleton, leading to dehydration and death. It is 100% non-toxic to humans and pets, yet kills cockroaches within 24–48 hours. Simply dust it under appliances, baseboards, and wall cracks and see the magic.
4. Borax + Sugar Mix
Borax works like boric acid by disrupting the digestive system of roaches. Mix equal parts of borax and sugar and place in lids or trays along the infested areas. Borax will kill them within 24 hours.
5. Dish Soap + Water Spray
Dish soap water is an effective method to kill cockroaches on contact. It breaks down the protective wax coating on cockroaches’ bodies and suffocates them. Mix 2 tablespoons of dish soap in 1 cup of water, shake it, and spray it directly to get rid of them overnight.
6. Ethanol or Rubbing Alcohol Spray
Use ethanol or rubbing alcohol spray. Alcohol pulls moisture from their bodies and destroys their cell walls. It also blocks their spiracles, killing them instantly on contact. However, make sure not to use it near heat sources since it is highly flammable.
7. Insecticide Spray (Imidacloprid/Cypermethrin)
These neurotoxins attract the roach’s nervous system and paralyze it, leading to death. Spray it behind the fridge, under sinks, and in cracks. The residual will also kill them even after a few days. So spray it in heavily infested areas. However, ventilate the room afterward before entering.
8. Gel Baits (Fipronil-Based)
Gel baits work better for heavily infested areas and kill the entire cockroach colony. Roaches consume the gel and return to their nest, where others ingest their feces or carcasses. This way, the poison is spread and kills up to 40 cockroaches at once. Apply gel baits inside drawers, hinges, cracks, and baseboard corners.
9. Cockroach Bait Stations
Cockroach bait stations combine an attractant and poison in a sealed container. Roaches enter the container, feed, and return to their nests to spread the poisons and kill the entire colony. It kills hidden populations over 1-3 days. Use 1 bait per 100 feet along the walls, near trash areas, and in kitchen corners.
10. Sticky Traps
These traps catch cockroaches that wander in with their adhesive and attractant. They do not kill them, but immobilize them. Place the traps near fridges, cabinets, and under sinks.
11. Essential Oil Spray (Peppermint, Eucalyptus)
You can easily get rid of them overnight with essential oil sprays. Oils like Peppermint and eucalyptus contain compounds like menthol and cineole. These overload a roach’s sensory system and repel them. Mix 10–15 drops of oil in a cup of water and spray around doors, baseboards, and cabinet interiors.
12. Professional Help
If none of the methods work due to severe infestation, hire a licensed pest control company. It will use non-repellent sprays and thermal foggers to reach nests inside walls and subfloors. Or learn to chase them and how to control cockroaches at home.
