Pesticide Safety: What Homeowners Need to Know

Pesticides play a crucial role in protecting homes and families from dangerous pests across Washington, Idaho, Oregon, and Arizona. However, concerns about chemical safety are valid and important. Understanding how pesticides work, what safety measures professionals take, and how to minimize risks empowers homeowners to make informed decisions about pest control. This comprehensive guide covers everything you need to know about pesticide safety, from EPA regulations to practical precautions for your family.

Understanding Pesticides

What Are Pesticides?

Pesticides are substances designed to prevent, destroy, repel, or mitigate pests. The term encompasses:

• Insecticides: Target insects (ants, roaches, mosquitoes, termites)
• Rodenticides: Control rodents (mice, rats, voles)
• Herbicides: Kill unwanted plants (weeds)
• Fungicides: Control fungal growth (mold, mildew)
• Repellents: Deter pests without killing them

How Pesticides Work

Mode of Action:

• Contact poisons: Kill pests on contact
• Stomach poisons: Must be ingested to work
• Systemic poisons: Absorbed and distributed throughout pest's body
• Fumigants: Gaseous pesticides that penetrate enclosed spaces
• Growth regulators: Disrupt pest development and reproduction

Selectivity:

• Broad-spectrum: Affect many pest species (and potentially beneficial insects)
• Selective: Target specific pests while minimizing impact on non-target organisms
• Targeted application: Modern pest control emphasizes selective products and precise application

EPA Regulation and Safety Standards

The Registration Process

Before any pesticide can be sold or used in the United States, it must be registered by the Environmental Protection Agency (EPA). This rigorous process includes:

1. Extensive testing: Manufacturers must conduct studies on:
   • Acute toxicity (immediate effects)
   • Chronic toxicity (long-term effects)
   • Carcinogenicity (cancer risk)
   • Reproductive effects
   • Developmental effects (birth defects)
   • Neurotoxicity (nervous system effects)
   • Environmental impact
2. Risk assessment: EPA evaluates potential risks to:
   • Human health (applicators, residents, bystanders)
   • Wildlife and ecosystems
   • Water quality
   • Air quality
3. Label requirements: Every pesticide must have a label specifying:
   • Approved uses
   • Application rates and methods
   • Safety precautions
   • Re-entry intervals
   • Environmental hazards
   • First aid measures
4. Ongoing review: EPA re-evaluates registered pesticides every 15 years to ensure they meet current safety standards

• Storage hazards: Improper storage creates risks for children and pets
• Disposal problems: Incorrect disposal pollutes environment

Safety Precautions for Homeowners

Before Treatment

1. Ask questions:
   • What products will be used?
   • What are the active ingredients?
   • Are they safe for children and pets?
   • What precautions should you take?
   • When can you re-enter treated areas?
2. Prepare your home:
   • Remove or cover food, dishes, and utensils
   • Remove pets (including fish tanks if fumigating)
   • Clear treatment areas of toys and personal items
   • Provide access to all areas requiring treatment
3. Inform your technician:
   • Presence of children, pregnant women, or elderly
   • Pets and their locations
   • Anyone with allergies or sensitivities
   • Recent illnesses or health concerns

During Treatment

• Leave the area: Vacate treated areas during application
• Keep children and pets away: Ensure they cannot access treatment areas
• Ventilate: Open windows if treating indoors (unless fumigating)
• Don't interfere: Allow technician to work without interruption
• Take notes: Record what was treated and where

After Treatment

1. Observe re-entry times: Wait the specified period before entering treated areas
2. Ventilate: Air out treated areas before re-entry
3. Avoid contact: Don't touch treated surfaces until dry
4. Clean carefully: Wipe down surfaces that children or pets contact (counters, floors)
5. Monitor for reactions: Watch for unusual symptoms in family members or pets
6. Follow instructions: Adhere to any specific post-treatment guidelines

Special Considerations

Children

• Children are more vulnerable to pesticide exposure due to:
  • Higher breathing rates (breathe more air per pound of body weight)
  • More hand-to-mouth contact
  • Play on floors and lawns where pesticides may be applied
  • Developing nervous and immune systems
• Extra precautions:
  • Request low-toxicity products
  • Ensure longer re-entry times
  • Thoroughly clean play areas after treatment
  • Wash toys that may have been exposed
  • Keep children away from treated areas until completely dry

Pets

• Dogs and cats:
  • Remove during treatment
  • Keep away until surfaces are completely dry
  • Wash pet bedding if in treated areas
  • Monitor for unusual behavior after treatment
• Birds and fish:
  • Extremely sensitive to airborne chemicals
  • Remove from home during treatment
  • Cover aquariums and turn off pumps if removal not possible
  • Wait several hours before returning birds to treated areas
• Reptiles and amphibians:
  • Sensitive to chemicals due to permeable skin
  • Remove from treatment areas
  • Ensure complete ventilation before return

Pregnant Women

• Some pesticides may pose risks to developing fetuses
• Recommended precautions:
  • Inform pest control company of pregnancy
  • Request lowest-toxicity options
  • Leave home during treatment
  • Wait extended period before re-entry
  • Ensure thorough ventilation
  • Consult physician if concerned

Individuals with Sensitivities

  • Ensure excellent ventilation
  • Consider alternative treatments (baits, traps)
• Chemical sensitivities:
  • Discuss sensitivities with pest control company
  • Request Material Safety Data Sheets (MSDS)
  • Consider non-chemical alternatives
  • Extend re-entry times

Safer Alternatives and IPM

Integrated Pest Management (IPM)

IPM is an ecosystem-based strategy that focuses on long-term prevention through a combination of techniques:

1. Prevention: Eliminate conditions that attract pests
2. Monitoring: Regular inspections to detect problems early
3. Identification: Accurate pest identification for targeted control
4. Thresholds: Determine when action is needed (not every pest requires treatment)
5. Control methods: Use least-toxic effective options first:
   • Cultural controls (sanitation, exclusion)
   • Mechanical controls (traps, barriers)
   • Biological controls (natural predators)
   • Chemical controls (only when necessary, using least-toxic options)
6. Evaluation: Assess effectiveness and adjust strategy

Low-Toxicity Options

• Baits: Targeted delivery minimizes exposure to non-target organisms
• Boric acid: Low toxicity to mammals, effective against insects
• Diatomaceous earth: Physical mode of action (desiccation), non-toxic to mammals
• Insecticidal soaps: Low toxicity, effective against soft-bodied insects
• Horticultural oils: Smother insects, minimal environmental impact
• Botanical insecticides: Plant-derived (pyrethrins, neem), break down quickly
• Microbial insecticides: Bacteria or fungi that target specific pests (Bt for caterpillars)
