6 Tips to Control Cockroaches

Cockroaches are one of the most dreaded pests that can invade a home.

These quick-moving insects that can survive for a month without food are masters of infiltration and adapting to their environment. Getting rid of cockroaches requires diligence and patience, but it can be done with the right techniques and products.

Eco Pest Control Adelaide is here to share various methods for controlling a cockroach infestation in your home.

What Lures Cockroaches?

Cockroaches are attracted to food and water sources, as well as warmth and humidity. They can squeeze into the smallest cracks and crevices to gain access to your home. Kitchens and bathrooms provide ideal conditions for cockroaches, with access to water from sinks and pipes. Food crumbs and spills also entice cockroaches, along with pet bowls left out overnight. Clutter and cardboard provide excellent hiding spots for these pests.

Keeping your home clean and dry is key to preventing an infestation. Caulking cracks in walls, floors, and around pipes deprives cockroaches of entry points. Storing dishes in tightly sealed containers also discourages cockroaches from taking up residence in your kitchen.

How to Eliminate Cockroaches

There are several effective methods for controlling and eliminating cockroaches:

1. Sprays

Insecticide sprays containing chemicals like pyrethroids are highly effective in instantly eradicating cockroaches. Look for ones specifically formulated for cockroaches. Concentrate the spray in areas where you’ve seen cockroaches and their droppings, like under appliances and along baseboards. Repeated applications are needed to fully disrupt the population.

2. Baits

Baits contain poison mixed with food to attract and kill cockroaches. They come in jars, discs, or strips. Place them along walls and in corners where cockroaches travel. The bait works slowly as cockroaches eat it and bring it back to their nests, eventually wiping out the entire colony. Refresh baits monthly.

3. Gels

Gels use the same poisons as baits but deliver it in a paste form. Apply small drops of gel near cracks and crevices where cockroaches hide. The gel sticks to their bodies as they crawl through it, poisoning them. It’s an effective way to eliminate cockroaches in wall and cabinets. Reapply every 2 weeks.

4. Bombs

Foggers or bombs fill an enclosed space with insecticide, instantly eliminating cockroaches. Remove pets and cover dishes, then set off the bomb and leave for 4+ hours. The spray reaches hidden crevices. bombs work best with other methods like baits or gels for complete control.

5. Traps

Glue traps and cockroach motels use no chemicals. Set them along walls, under appliances, or where you’ve seen cockroaches. The adhesive traps cockroaches when they cross over. For motels, cockroaches enter but can’t exit once they eat the bait inside. Check traps frequently to monitor activity. Replace spent traps.

6. DIY Remedies

For a non-toxic option, you can make bait with boric acid powder, sugar, and flour. Sprinkle this mix in out-of-reach areas. Boric acid kills cockroaches slowly after they ingest it. Bay leaves and catnip repel cockroaches. Sprinkle them in cabinets and drawers. Create citrus oil sprays as a natural repellent. Diatomaceous earth scratches their exoskeletons, causing dehydration. Apply a fine dusting under and behind appliances.

Cockroach Control Tips

Cockroach Control Tips

  • Inspect your home thoroughly to find entry points and areas of activity. Target control methods to those locations.
  • Use a combination of techniques like baits, gels, and sprays for better results.
  • Hit cockroaches quickly and repeatedly to break the reproduction cycle.
  • Caulk and seal cracks to prevent access.
  • Clean spills immediately, and store dishes in sealed containers.
  • Don’t allow dishes to sit in the sink overnight.
  • Fix leaky pipes to eliminate water sources.
  • Vacuum and sweep often to remove cockroach egg casings.

Signs of an Infestation

Seeing live cockroaches is an obvious sign. But also look for:

  • Egg casings that look like capsules
  • Molted exoskeletons
  • Droppings like coffee grounds
  • An odor from their scent glands
  • Grease marks from their movements

Even just one German cockroach, an American cockroach, or any type of cockroach can indicate a larger hidden population. Take action at the first signs to halt further breeding.

How to Prevent Roaches

Sanitation is key. Keep your kitchen and bathrooms clean and dry. Eliminate access by sealing cracks and gaps. Fix plumbing leaks and clean up spills right away. Store dishes in sealed containers. Inspect packages and produce for hitchhiking cockroaches. Avoid leaving pet food out overnight. Monitor sticky traps under appliances. If caught early, you can stop cockroaches before they multiply into a full-blown infestation.

How to Prevent Cockroaches


Controlling a stubborn cockroach infestation takes diligence, but combining products and techniques can suppress populations. Insecticide sprays, baits, gels, and traps all play a role in knocking down an established infestation.

Maintaining cleanliness and sealing off entry points denies cockroaches water and shelter. Stopping them early prevents drastic measures later.

With persistence and thoroughness, you can kick cockroaches out of your home for good.
