Because of their size and coloration, water bugs are frequently confused with cockroaches. However, they have distinct features that set them apart.

Here’s how you can identify water bugs:

ColorTypically dark brown or reddish-brown, similar to cockroaches.
BodyOval-shaped and bulkier compared to the flatter cockroaches.
LegsLarger, more powerful legs, intended for swimming.
AntennaeAntennae are shorter than those of cockroaches.
MouthpartsEquipped with piercing mouthparts for capturing prey.

2. Crickets


Crickets share some similarities with cockroaches, such as their color and the fact that they both have antennae. However, crickets have their unique traits:

  • Chirping Sound: Crickets are known for their distinctive chirping, especially at night.
  • Jumping Ability: Unlike cockroaches, crickets have strong hind legs for jumping.
  • Body Shape: Crickets are more cylindrical, whereas cockroaches are oval and flattened.
  • Coloration: Crickets tend to be lighter brown, though some species can be darker.

3. Ground and June Beetles

In Louisiana, it’s crucial to distinguish between cockroaches and other pests that may appear similar. Doing so can aid in proper identification and management strategies for homeowners.

Bed Bugs

Bed bugs and cockroaches exhibit several vital differences. To identify these pests in your home, look out for the following:

  • Bed Bugs: Small blood stains on sheets, itchy bite marks in a line or cluster, and a musty odor near your bed.
  • Cockroaches: Droppings that resemble coffee grounds or black pepper, a strong oily or musty odor, oval-shaped egg cases in hidden areas.


Unlike cockroaches, termites cause remarkable damage to the wooden structures they feed.

To differentiate between termites and cockroaches, consider their physical and behavioral characteristics summarized in the table below:

ColorPale, white, or light brownDark brown to black, sometimes with reddish hues
ThoraxElongated with no waistBroad with a defined waist
AntennaeStraightBent or curved
Wings (if present)Two pairs of equal-sizeTwo pairs, the front set longer
DietCellulose (wood)Omnivorous, eats almost anything
DamageErode wooden structuresContaminate food and surfaces


Here’s how you can make your homes less attractive and avoid a cockroach infestation:

  1. Seal Entrances: To block entry points, homeowners should seal cracks and crevices, especially in kitchens and basements.
  2. Regular Cleaning: Keeping houses clean, especially free of food crumbs and organic matter, deters cockroaches.
  3. Proper Food Storage: Store food in sealed containers to avoid attracting cockroaches.
  4. Fix Water Leaks: Eliminate moisture by repairing leaks in sewers and basements since cockroaches are drawn to water sources.
  5. Declutter: Remove clutter from basements and crawl spaces to reduce hiding spots.
  6. Trash Management: Use covered garbage cans and dispose of trash regularly to reduce food sources.

At LaJaunie’s Pest Control, we offer comprehensive cockroach control. Here’s an overview of how we effectively manage each type:

German Cockroaches

German cockroach (Blatella germanica
  • Treatment Needs: German cockroaches require a specialized approach due to their rapid reproduction rates. An Insect Growth Regulator (IGR) is essential to disrupt and inhibit the development of nymphs.
  • Homeowner Involvement: Successful eradication often requires active cooperation from the homeowner to ensure the environment doesn’t support reinfestation.
  • Initial Service: Priced at $280, which includes a critical follow-up after two weeks.
  • Additional Follow-up: If necessary, a third visit on the 4th week is provided at no extra cost to ensure complete eradication.
  • Subsequent Treatments: After the initial phase, quarterly services are recommended to maintain a cockroach-free environment.

Other Cockroach Species (American, Brown-Banded, Australian)

  • Treatment Approach: These species are generally more responsive to standard treatments and can effectively be managed with granular baits and other standard pest control methods.
  • Service Routine: Regular pest control services, typically quarterly, are recommended to prevent future infestations.
