Chemical Treatment to Get Rid of Indoor Cockroaches

Cockroaches are high-risk pests to have in your home and business premises. The risk is even higher in the food business sector, from contaminating food and causing property damage to a serious threat to health.

However, there are several chemicals that can be used to eliminate the roaches’ existence. The important thing to remember is that this must be done by the expert and licensed authorities only since it contains a lot of insecticides that are harmful to human health.

1. Avermectin – High acute toxicity in pure form.
   
   However, the used concentration in baits is less than 0.01% and has low acute toxicity. Take note that it is toxic to the nervous system and developing fetus at low doses. It is not absorbed through the skin much, but it is toxic to aquatic animals.

It can be used in the form of gel, solution, aerosol, granular, impregnated materials, and dust.

• Borates – It contains Borax, Boric acid Sodium metaborate.
  
  It has low acute toxicity and cannot be absorbed through skin. It is toxic to plants. Consumption of a small quantity daily for months reduces sperm counts in animals.

It is used in the form of gel, dust, paste, granular, solution, and aerosol.

• Diatomaceous Earth – Contains crystalline silica. Causes lung irritation when inhaled. Long-term exposure to DE dust is associated with lung cancer.

It can be used in the form of dust.

• Fipronil – Moderately acutely toxic by ingestion, but does not absorb much through the skin. Toxic to the nervous system and classified as a Possible carcinogen by US EPA. High toxicity to birds and aquatic life.

It can be used in the form of powder, pellets, gel, impregnated materials, solution, and granular.

• Hydramethylnon – Low acute toxicity to humans. Not absorbed much through the skin. Toxic to the developing fetus and interferes with reproduction at moderate doses. High toxicity to aquatic life.

It can be used in the form of granular, pellets, gel, and solution.

• Indoxacarb – Has moderate to low acute and chronic oral toxicity to humans. High toxicity to aquatic life.

It can be used in the form of impregnated materials, gel, solution, and granular.

It can be used in the form of impregnated materials, aerosol, and solution.

• Neonicotinoids – (Acetamiprid, Clothianidin, Imidacloprid, Thiamethoxam) Moderate acute toxicity to humans and are absorbed through the skin to some extent. Toxic to the nervous system. Imidacloprid reduces sperm counts in laboratory animals with long-term exposures. Highly toxic to aquatic invertebrates and bees.

It can be used in the form of aerosol, impregnated materials, gel, granular, and solution.

• Pyrethroids – (Allethrin, Bioallethrin, Cyfluthrin, Cyhalothrin, Cypermethrin, Deltamethrin, Esfenvalerate, Permethrin, Tetramethrin, Tralomethrin) Moderate acute ingestion, and inhalation toxicity. Sensitizer, causing allergy and asthma in some people. Toxic to the nervous system. Highly toxic to aquatic invertebrates and bees.
  
  Most products also contain a synergist that increases the insecticidal activity of the pyrethroid. Piperonyl butoxide (PBO) and N-octyl bicycloheptene dicarboximide are typical synergists and both are possible carcinogens as per US EPA.

It can be used in the form of solution, aerosol, and granular.

1. Organophosphates – (Acephate, Chlorpyrifos, DDVP, Malathion, Naled, Propetamphos) High acute toxicity to humans at low concentrations. Toxic to the nervous system, especially for children. Highly toxic to aquatic life.

It can be used in the form of granular, impregnated materials, solution, and aerosol.

1. N-Methyl Carbamates – (Carbaryl Propoxur) High acute toxicity to humans at low concentrations. Toxic to the nervous system, especially for children. Highly toxic to aquatic life.

  Care to be taken of airborne and fallen droplets. While using, all flames must be extinguished.

• Botanicals – Naturally occurring insecticides processed and concentrated. Nicotine sulphate, a botanical insecticide must be used carefully as it is more toxic to humans than other synthetic insecticides.

• Emulsifiable Concentrates – Formulated emulsifiable concentrates contain a lower concentration of active ingredients. They are easy to mix and need a little stirring.

• Ready-to-use sprays – Formulated ready-to-use sprays are already diluted by the manufacturers, so, it can be used directly. They are safer as there is no mixing of concentrated insecticides. Care must be taken to avoid creating potential hazards due to leakage.

• Wettable Powders – These powdery formulations are added to water. A wetting agent helps the active ingredients to mix with water.
  
  The advantage of wettable powders is that if it is sprayed on wood, the residual activity keeps the powder on the surface but the water penetrates the wood. This results in great effectiveness.

• Cockroach Baits – Place the bait stations having active ingredients near the areas where the roaches are active. Roaches will reduce in some days while they eat the bait.
  
  Try different types of bait to avoid the roaches becoming resistant to one type.

• Oxypurinol and Xanthine – Oxypurinol is a metabolite of a drug and Xanthine is a natural substance found in all living things. When combined, these two work to block the formation of uric acid, which roaches need for metabolism and reproduction.
  
  Thus, the population of roaches gets stopped.

• Sulfuramid – Formulated as a cockroach bait, Sulfuramid is another active ingredient that delays the action on roaches. It has low toxicity to humans. It is available in tamper-proof bait stations.

• Boric Acid – It is formulated in both gel and granular form. It is a white powder toxic to roaches, ingesting which, they choke and they die.

• Make sure to cover all the areas where pests can hide such as under shrubs, trees, dense fossils, or long grass.
• Use of toxic gels, sprays, sticky traps, and baits stations or a combination of them to reduce the population of roaches.
