Get a useful proposal, not just a price.

Prepare for an inspection, ask about the work that matters and compare written proposals on the same basis.

Ask for the diagnosis before the price

A useful proposal names the organism or explains what remains uncertain, describes the evidence and shows the affected area. Ask to see photographs, specimens or inspection findings. A promise to “spray everything” does not explain why that treatment fits the problem.

  • Who inspected, and what could not be inspected? What evidence separates this pest from its lookalikes?
  • What conditions support the problem—entry gaps, moisture, food, host plant or neighbouring units—and who will correct them?
  • Which immediate actions can you take, and which proposed work depends on confirmation or further inspection?

Put the scope in writing

Work and preparation

  • Target pest, rooms or outdoor areas, method and preparation duties.
  • Products, where they will be applied, label precautions and who returns when.
  • What is included in exclusion, repair, disposal or cleanup—and what is excluded.
  • Access to neighbouring units or shared building areas, and who coordinates it.

Follow-up and payment

  • Initial charge, paid follow-up visits, mandatory fees and tax for the same period.
  • How success is measured, monitoring dates, and who responds to new activity.
  • Warranty conditions, exclusions, repeat-visit charges, renewal and cancellation.
  • A written record of work and any change requiring your agreement.

For termites, ask which termite group is implicated, how the proposed method fits it and what structural access is required. A treatment warranty is not automatically a warranty against all future damage.

For wildlife, check more than removal

  • Ask which species is present and how the operator checks for dependent young or an occupied nest. The season and species can change exclusion timing.
  • Confirm local authorizations, permitted methods and the legal destination of an animal if removal is proposed. Do not assume relocation is legal or humane.
  • Specify one-way exclusion if appropriate, permanent entry repairs and protection of ventilation. Who checks the animals have left before sealing?
  • Separate contamination assessment and safe cleanup from capture or exclusion. Bat accumulations and raccoon latrines are not ordinary household dust.
  • Record how attractants will be removed, what happens if an animal returns, and which repairs or visits are covered.

Use a local wildlife authority for legal advice; a company’s general service page cannot establish permission for your case.

Check the person and the offer

  • Verify the licence or certification required in your jurisdiction for the actual work, and ask about appropriate insurance. A familiar brand does not replace this check.
  • Ask for references and read the proposed contract carefully. A claim of urgency should be explained by the evidence, not used to stop you comparing suitable proposals.
  • Use at least enough written detail to compare the same work. A low initial price may exclude return visits, repairs or required preparation.
  • If a diagnosis or structural claim is uncertain, seek an independent qualified inspection.

Compare your actual proposals

The worksheet totals initial work, later paid visits and mandatory fees. It keeps each scope beside the amount; it does not select a “winner” or invent local prices.

Find the local decision-maker

In the United States, use the Association of Fish & Wildlife Agencies’ state directory to reach your wildlife agency. Ask about the species, occupied nests, dependent young, allowed methods and the operator’s authorization. Elsewhere, use the regional authority routes. Do not assume another region’s rules apply.

Maryland, United States: bat-roost help

Maryland DNR recommends exclusion from September 1 to March 1 only when bats are not hibernating in the building. Flightless pups and protected species need particular care. During March 1–August 31, DNR’s guidance requires exemption paperwork when there are 10 or more bats, a rare/threatened/endangered species, or pups. Ask DNR how these conditions apply before arranging work; a date alone is not permission.

Read the current DNR bat guidance. If its website will not open, the DNR nuisance-wildlife service lists 1-877-463-6497 from Maryland numbers, or 410-349-8055 from other numbers, and a licensed-cooperator directory. These are wildlife-information contacts, not emergency medical services.

For possible human contact, use the Maryland local health-department directory promptly; for pet contact, call a veterinarian. Preserve the exposure/testing decision before releasing a bat.

Record your locality, the authority contacted, advice date, species/young assessment, permitted timing, entry repairs, cleanup scope and follow-up in your notebook. Download the blank wildlife handoff sheet for a professional.
