Insecticides That Kill Water Bugs

Water bugs are a species of cockroach that is usually found outdoors in cool, damp areas. These insects are of the species Blatta orientalis, commonly called oriental cockroaches or black beetles. Though they do not bite or harm humans, water bug infestations can be unsightly and unsanitary. There are a variety of poison insecticides available that are recommended for the extermination of water bugs.

Water bugs are not invasive to homes. They thrive on organic and decaying matter, specially under leaves, mulch, and other shrubbery. Colonies are also found in dark, moist areas. They can inhabit basements, stone masonry, dumps, sewage systems, water pipes and crawl spaces. If water is scarce, the insects may travel indoors through ventilation systems, air ducts or under doors. They are poor climbers, and once inside, are not commonly found on walls, in high cupboards, or on upper floors. Water bugs tend to get trapped in bathroom fixtures after crawling through drains because they are unable to climb out.

Boric Acid
Boric acid powder can be spread around areas where water bugs are found. Some people prefer boric acid because it is a naturally occurring compound and not synthetically produced. Boric acid is available at hardware and discount stores.

Hydramethylnon comes in gel form or in a bait station that contain pellets of the poison. It is sold under the brand name Combat. This chemical is a bait-type poison that relies on water bugs retrieving and consuming it through strategically located receptacles containing the poison.

Another spray-on poison is cypermethrin(C23H19ClF3NO3, CAS No. 91465-08-6). This poison decomposes quickly in a natural environment, but it is long lasting when used indoors. Brand names for cypermethrin include Demon, Cynoff and Ammo. One drawback of cypermethrin is that it can leave behind a residue.

Dish Detergent
For water bugs that are harassing you in the swimming pool, just add a few tablespoons of dish detergent to the water. Once you get out of the pool for the day, add the detergent with the pump running. Allow the water to calm and when the sun goes down, turn the pool lights on. The water bugs will be drawn to the light but when they get in the pool, the detergent will have created a barrier on the water so that when the bugs go under, they can’t come back up for air.

What Is Cypermethrin?

Cypermethrin is a man-made compound that rapidly kills insects by affecting their central nervous system. It is also a neurotoxin that was originally created in 1974 and was used commercially and industrially starting in 1977. Since that time, it has become a popular choice for controlling moth pests on plants as well as spot treatments in a variety of industrial environments.

Cypermethrin is a stable compound when exposed to high heat and light. The molecular formula is C22H19O3NCl2. It is a pure racemic compound consisting of eight stereo-isomers and is also most stable at a pH value of 4. The physical properties vary from a viscous liquid to a semisolid crystalline depending upon the temperature at which it is stored. It can also appear yellow to brownish in color.

According to the science website, Cypermethrin kills harmful insects by causing central nervous system complications. Laboratory tests have shown that some insects quickly experience paralysis, restlessness, in-coordination and ultimately death after exposure to the chemical.

The compound is added to many commercially available pest control substances including Raid, Ammo and Demon. It is most commonly used to control pests, primarily moths, known to attack fruit, vegetable and cotton plants.

Because of its minimal environmental impact and effectiveness for prevention, cypermethrin is also commonly used as a barrier treatment in hospitals, schools and non-food areas of restaurants.

Insecticides containing cypermethrin are also used for spot treatment of insects in areas that are cracked or contain crevices that are difficult to reach. Applications are in commercial and industrial buildings, such as warehouses, and transportation vehicles like aircraft and buses.

Cypermethrin is not toxic to groundwater or plants, which is why it is often selected for insect control near vegetation. However, it is known to be very toxic when fish and aquatic invertebrates come into contact with the chemical.

Humans experience drastically different symptoms than small animals and insects when exposed to cypermethrin. When handled by people, the chemical can lead to tingling, dizziness, itching or burning. It is also rapidly excreted by the body and is therefore unlikely to build up with repeated exposure.

The compound can be inhaled. This is mostly likely to happen to a person who is applying the pesticide. If she has a respiratory condition or infection, then the chemical can affect her by exacerbating the condition. Cypermethrin(CAS: 52315-07-8) can have adverse effects on a person’s digestive system. This can happen if he absorbs the pesticide through his skin or in the unlikely event that he ingests it. He can experience intense nausea, vomiting and diarrhea.

Breakdown of cypermethin in soil can range from two to eight weeks depending upon the ground’s composition. It does not lead to groundwater contamination because the chemical does not readily move around in soil. It is, however, highly toxic to fish upon exposure.
