Key Takeaways

  • Spotting signs of German cockroach infestations, like droppings, musty odors, and shed exoskeletons, indicates potential health risks.
  • DIY cockroach control strategies include eliminating hiding spots, securing food sources, and employing natural repellents to deter roaches.
  • Professional pest control services offer targeted treatments, providing tailored solutions for German cockroach infestations.
  • When facing a persistent or large German cockroach infestation in Louisiana, it’s essential to seek professional help, considering factors like company certifications, specialization, and the offer of free inspections.


Before tackling an infestation, you must recognize the signs of a German cockroach infestation.

So, as homeowners, you should be vigilant about the following indications:

  • Droppings or Feces: Small, pepper-like specks near food sources or damp areas.
  • Egg Cases (Oothecae): Small, brown, capsule-shaped containers that hold numerous eggs.
  • Musty Odor: A distinct, unpleasant smell that lingers in infested areas.
  • Light Brown Roaches: German roaches are light brown with two dark stripes behind the head.
  • Exoskeletons: Shed skins after molting are often found near areas where roaches frequent.

These signs are alarming because they pose health risks. This species of cockroaches carries allergens that cause allergic reactions and pathogens like salmonella.


Achieving effective DIY cockroach control involves a multi-faceted approach. Here’s how to create a hostile environment for these unwelcome guests with DIY pest control:

DIY MethodDescription
Eliminate Hiding SpotsTo reduce potential roach hiding places, regularly dispose of trash and declutter spaces, especially removing items like cardboard boxes.
Secure Food SourcesStore all food in sealed and airtight containers and ensure pet food isn’t left out, cutting off their food supply.
Maintain CleanlinessKeep your kitchen pristine by washing dishes immediately and routinely wiping down surfaces to remove food residues.
Utilize Boric AcidFor a potent cockroach deterrent, apply boric acid along areas where cockroaches frequent, such as baseboards and cabinet edges.
Seal Entry PointsUse caulk to seal off any cracks and openings, particularly in places prone to dampness or darkness, to prevent cockroaches from entering from outdoors or neighboring areas.
Control MoistureAddress any leaks promptly and consider using dehumidifiers to reduce humidity, which will make the environment less appealing for cockroaches.
Employ Natural RepellentsIncorporate natural deterrents like diatomaceous earth around potential entryways and inside cabinets to further discourage cockroach invasions.

Combined with the strategic application of roach control products, this strategy can significantly reduce and get rid of cockroach populations. 

When to Use Sprays and Insecticides

Before you use these products to deal with your German cockroach problem, here’s what you need to consider:

  • Opt for sprays and pesticides labeled for use against German cockroaches.
  • Select products safe for indoor use, ensuring they won’t harm pets or humans.
  • Read labels carefully for application instructions and safety precautions.
  • Use these products in areas where roaches are seen, but keep away from food preparation spaces.
  • Contact a professional pest control service for advice on the best and safest products.
