Cockroaches are not only a nuisance — these pests also pose health risks and can spread diseases. This article will guide you through identifying roaches, various methods to eliminate them and how to prevent their recurrence.
- Cockroaches are nocturnal pests that can spread diseases. Identification involves looking for signs like droppings, an oily odor and egg cases.
- Eliminating roaches involves methods like sealing your home, applying pesticides, using natural remedies and hiring pest control professionals.
- Preventing infestations involves sealing entry points, maintaining cleanliness and doing regular yard maintenance.
Before you start any treatment, confirm that you’re dealing with cockroaches. They’re typically brown or black, can range anywhere from 0.07 inches to 3 inches long and have six legs and two antennae. Some species have wings, although not all are good flyers.
Cockroaches are nocturnal creatures, so if you spot one during the day, it could be a sign of infestation. Other signs include droppings that resemble ground coffee or black pepper, an oily or musty odor and oval-shaped egg cases.
11 ways to get rid of roaches
Eliminating cockroaches can be a daunting task, but with the right methods, you can get rid of these pests. Here are some effective methods:
1. Sealing your home
First, seal your home to keep more roaches from getting inside. Look for cracks and crevices around your windows and doors, and fill them in with caulk. Then install door sweeps and weatherstripping around any gaps near entryways. Be sure to check your home’s interior and exterior to ensure there aren’t any places roaches could squeeze in.
2. Bait stations
Bait stations contain food that attracts roaches. These baits are laced with pesticides that roaches carry back to their nests, poisoning the other roaches. Bait stations are effective, but they may take several weeks to eliminate the entire infestation. Gel baits can be applied under the lip of your counter or on the hinges of your cabinets for a more targeted approach.
Roaches can be eliminated by a variety of insecticides or natural methods.
3. Liquid pesticides
Liquid pesticides can be used to control severe infestations. These pesticides are applied to areas where roaches have been spotted, such as cracks, crevices and under appliances.
Always follow the instructions on the pesticide label, and keep pets and children away from treated areas. Concentrates can be particularly effective at preventing reinfestation, since they usually deter roaches for one to two weeks or more.
4. Insecticide sprays
Insecticide sprays can kill roaches on contact. Whenever you see a cockroach, spray it directly with the insecticide. You can also apply the spray on areas where roaches frequent to kill any roach that comes into contact with it. If you don’t have any spray on hand, try misting the cockroaches with rubbing alcohol to kill them.
5. Roach foggers
A roach fogger, also known as a roach bomb, can be an effective method for dealing with a large infestation. These foggers work by releasing a pesticide mist into the air that settles onto the surfaces in your home, killing roaches that come into contact with it.
Use this method with caution — it requires you to vacate your home for several hours and thoroughly clean all surfaces afterward. Always follow the instructions on the product label to ensure safe and effective use.
6. Baking soda
Baking soda is a great way to get rid of cockroaches and is completely safe for your family and pets. Mix some baking soda with sugar to create a roach killer — the roaches are attracted to the sugar and ingest the baking soda, which reacts with their stomach acids, causing their stomach to burst and killing them.
This method can be a bit slower, but it's a natural and safe way to handle a roach problem.
7. Adhesive traps
Adhesive traps are another effective method. These traps contain a sticky substance that roaches get stuck to when they walk over them. Place these traps in areas where you've seen roaches for the best results. In a pinch, make your own sticky traps by wrapping a piece of cardboard in duct tape so the adhesive is facing out.
8. Diatomaceous earth
Roaches get dehydrated when they walk through diatomaceous earth. Use a bulb syringe to spread the diatomaceous earth, and apply a thin layer around cracks and crevices so cockroaches have to walk through it. Try spreading it in other places too, such as underneath your sinks, along baseboards and inside cabinets.
9. Essential oils
Certain essential oils are toxic to cockroaches. Look for thyme oil, clove bud oil or citronella oil — these are typically the most effective at getting rid of young cockroaches. Spray the essential oil directly on the cockroaches when you see them. Otherwise, just spread the oil around the baseboards where you’ve seen cockroaches most frequently to keep them away.
10. Boric acid
Dust a thin layer of the boric acid powder into the cracks around cabinets and baseboards. Leave the boric acid for about one week before vacuuming it up and replacing it.
To attract more roaches to the boric acid, mix in one part powdered sugar or flour to create a homemade bait trap. Roaches are drawn to the food source and are more likely to ingest the boric acid.
11. Hire a professional pest control company
If the infestation is too large or the roaches keep returning, it might be time to hire a professional pest control company. These experts have access to powerful tools and pesticides that can eliminate roaches more effectively and prevent them from returning.
They can also provide advice on how to keep your home roach-free in the future, offering tailored solutions based on your specific situation and the layout of your property.
