It is the turn to talk about the water cockroach and roaches, and it is essential to mention that this cannot be given a specific scientific name, as it is dealing with several species of this.

However, if we want to generalize, we can say that it is part of the insects called Belostomatidae, specifically of a genus called Lethocerus.

What we generally know of the aquatic cockroach, is that this is an aquatic hemipteran insect, which can perform different skills, such as and worth the redundancy, being a marine animal.

Are water bugs and roaches the same thing?

Mentioning some of the specifications of this curious cockroach, these can measure up to a maximum of 15 cm, being one of the giant roaches that can have; however, its length depends on the species of aquatic cockroach to which we are referring specifically.

To the legs of these aquatic cockroaches, there is usually two back of each side, which is thick and serves for this insect to hunt its victims to devour them later.

The other hind legs are used for swimming, that’s right, they make swimming easier when they act as if the cockroach beats, that is, the hind legs that are not those of hunting, are the ones that allow you to have the ability to swim.

These cockroaches have beneficial skills.

Difference between water bugs and roaches

The Water Cockroach is also a bed bug, and these have between a half and two-thirds of the wing something earlier coriacea and the posterior half or third membranous and translucent.

The genus Lethocerus is distributed in tropical freshwater environments. The difference between roaches and water bugs is they are large, robust, and voracious water bugs. They are active predators and can feed on small fish, tadpoles, adult amphibians, and other insects. The proboscis is tubular, robust, and short, and they inject a liquid that paralyzes their prey and then suck body fluids from them. They live in aquatic habitats of running or stagnant freshwaters, such as rivers, streams, or lagoons.

It is an efficient predator that stalks without a move from the surface of the water until it detects movement. It then quickly heads towards its target and hunts it down, helping himself with his eyesight when he’s pretty close. Its “saliva” is toxic and can produce an excruciating sting to humans, so the less we manipulate her, the better. Some species lay their eggs on the stems of plants associated with the bodies of water, others deposit them on the “back” of the male, becoming a kind of wet nurse.


Indeed, the bite of the water cockroach is usually poisonous, and the poison contained in its saliva. As for the water-borne cockroach, this poison, found in the saliva of the aquatic cockroach, can cause symptoms and some somewhat visible damage to the health of us humans when we have suffered a bite of this species.

One of the damages and symptoms can be edema, and pains that come as a result of proteolytic reactions can produce a rash on the skin and its redness.

However, if you have suffered from one of these aquatic cockroach bites, you can proceed to make the correct treatments that, after some time, may disappear all the consequences that the bite has caused, in a complete way, that is, you will not suffer more pain, nor will be a trace of the taste.

Home remedy to get rid of water bugs and roaches

If you have observed these aquatic insects living in your pool, you can eliminate them directly using the following method:

  1. In a spray bottle, dilute three tablespoons of liquid dish soap. The size of the container will depend on the size of the pool, for example, for a small pond, 470 ml will suffice, and if it is large double this volume. The pool water is not affected, because the amount of soap is low and will biodegrade.
  2. Look for insect clusters in your pool that can serve as food for the water cockroach and spray them directly. You can also spray the solution directly onto the surface of the lake, concentrating on areas where errors may form. The soap will spread over the surface of the water by altering its surface tension, preventing insects from stopping or creating air bubbles.
  3. Spray the solution around the entire perimeter of the pool, aiming at the edge of the water without spraying the sides of pool walls.
  4. Use a pool foamer daily to remove algae and water cockroaches from the surface. Regular maintenance will help keep the insect problem under control. Once a day, clean the surface of your pool with a manual mesh skimmer, eliminating any giant insects.
  5. If you can capture water cockroaches, place them in a bucket full of water with three tablespoons of liquid dish soap, leave it covered for a few hours. When it uncovered, the insect will be dead.
