The Effects of Inhaling Raid Ant & Roach Spray

The convenience of spray insecticides, such as Raid Ant & Roach Spray, allows the homeowner to quickly lay down a defensive barrier against the invasive little pests. While easy to apply, users should be aware of the dangers of inhaling or otherwise ingesting the chemicals in the spray. Accidentally inhaling the spray can cause irritation to the nose, throat and lungs. It can also affect the central nervous system in high doses.

Respiratory Effects

The National Library of Medicine's Toxicology Data Network reports that at the time of exposure, cypermethrin -- one of two active ingredients in Raid Ant & Roach Spray -- can cause shortness of breath, coughing and congestion. It can also cause an asthma attack and wheezing.

Inhaling cypermethrin may also cause a hypersensitive reaction that leads to pneumonitis and pulmonary edema.

Among the symptoms reported after inhalation of imiprothrin, the second active ingredient, are airway irritation, dizziness, headache and sneezing. There have been reports of respiratory paralysis and cardiac arrest, but these reactions are rare.

Skin Reactions

In addition to inhalation, overspray may get on the user's skin. While the spray can cause a skin reaction, quickly washing with soap and water removes the residue. If skin irritation develops, see the doctor.

Wasp and Hornet Spray

Homeowners may also use wasp and hornet sprays to kill wasps building nests on or near the house. Raid Wasp & Hornet Killer 33 contains cypermethrin and prallethrin. It causes respiratory distress if inhaled, including coughing and wheezing, as well as dizziness, headache and burning or itching of the face.

Safe Practices

When using any spray pesticide, avoid inhaling the product. A long-sleeved shirt, long pants, shoes, gloves, a dust mask and safety goggles protect the skin, lungs and eyes from accidental exposure. Wash your hands with soap and water immediately after using the spray. Change your clothes and put the exposed clothing in the washer, and wash with hot water and laundry detergent.

Active Ingredients

Imiprothrin and cypermethrin, the active ingredients that make up 0.1 percent of Raid Ant & Roach Spray, are pyrethroids, which are synthetic insecticides. They are based on the naturally occurring pyrethrins found in Chrysanthemum cinerariifolium. Pyrethrins and pyrethroids are highly toxic to insects, honeybees and fish.
