Adams Flea & Tick Carpet Spray

Risk Level: 
Use sparingly and avoid if pregnant or around young childrenUse sparingly and avoid if pregnant or around young children
Description:

Spray for carpets, drapes, rugs, upholstered furniture and pet bedding.

Chemicals:
S-Methoprene -- 

S-Methoprene is an Insect Growth Regulator (IGR), meaning that it halts the growth of chitin, the substance that creates the exoskeleton in insects. IGRs are effective against developing insects but not against adult insects with already developed exoskeletons. Because of this, IGRs are used to prevent an extended infestation. Since mammals do not produce chitin, insect growth regulators have little effect on humans. According to EPA S-Methoprene has a very low acute toxicity. [source]

S-Methoprene is listed as a least-toxic chemical control by the Integrated Pest Management Practitioner. It is listed on City and County of San Francisco Integrated Pest Management Program 2007 Reduced-Risk Pesticide List. [source] And it is listed on EcoWise Certified IPM Program Materials List.

Toxicity:
  • Safer chemical -- however, all pesticides should be used with caution and in consultation with a veterinarian.
Etofenprox -- 

Etofenprox is one of a class of synthetic chemicals, called pyrethroids, that are derived from natural chemicals found in chrysanthemums. The synthetic varieties are significantly more potent and persistent than naturally occurring products. Exposures to pyrethroids can result in a variety of symptoms, especially in pets, including drooling, lethargy, muscle tremors, vomiting, seizures and death. Toxicity symptoms in humans include asthmatic breathing, sneezing, nasal stuffiness, headache, nausea, incoordination, tremors, convulsions, facial flushing and swelling, and burning and itching sensation. [note #1] Early studies suggest that exposure to pyrethroids could impact the developing brain. [source] Etofenprox also disrupts the endocrine system, specifically thyroid hormone, and is toxic to the developing nervous system. Etofenprox, like other pyrethroids is known to be very toxic to cats, causing muscle tremors, seizures, salivation, vomiting and even death. Veterinarians caution against using pyrethroid containing products if there are cats in the home.

Toxicity:
  • Toxic to the nervous system
  • Endocrine disruptor
  • Very toxic to cats
Prallethrin -- 

Prallethrin is one of a class of synthetic chemicals, called pyrethroids, that are derived from natural chemicals found in chrysanthemums. Exposures to pyrethroids can result in a variety of symptoms, especially in pets, including drooling, lethargy, muscle tremors, vomiting, seizures and death. Toxicity symptoms in humans include asthmatic breathing, sneezing, nasal stuffiness, headache, nausea, incoordination, tremors, convulsions, facial flushing and swelling, and burning and itching sensation. [note #1] Early studies suggest that exposure to pyrethroids could impact the developing brain. [source] Prallethrin is listed by the European Union as an endocrine disruptor. Pyrthroids are known to be very toxic to cats and owners should be cautioned against using them if cats are present in the home.

Toxicity:
  • Toxic to the nervous system
  • Suspected endocrine disruptor
  • Very toxic to cats
N-Octyl Bicycloheptene Dicarboximide (MGK 264) -- 

N-Octyl Bicycloheptene Dicarboximide (also MGK-264) is an insecticide synergist which is combined with other insecticides to increase the effectiveness of the chemical. [source] It has been classified as a possible carcinogen and a potent skin and eye irritant. [source] Recent studies suggest synergists may also increase the toxicity of other pesticides with which they are applied.

Toxicity:
  • Possible human carcinogen
  • Skin irritant
  • Eye irritant
Safer Alternatives: 
  • Wash bedding in hot, soapy water once a week.
  • Vacuum the home once a week. Empty the vacuum bag and dispose its contents.
  • Comb daily with a fine-toothed flea comb and rinse the comb teeth in hot, soapy water between strokes.
  • Look for repellent sprays made with essential oils of lemongrass, cedarwood, peppermint, rosemary or thyme.
  • For severe problems that require chemical intervention, look for lower risk products such as those using Pyriproxyfen, Nitenpyram, Spinosad, S-Methoprene, or Lufenuron as the active ingredient.
