The 30–60 minute window
Every product we use is EPA-registered, and every label has a specific "re-entry interval" — the time you should wait before kids, pets, or food prep returns to the treated area. For the residual perimeter products we use most (Suspend Polyzone, Demand CS, Talstar P, Temprid FX), the interval is until dry, typically:
- Indoors: 30 minutes on hard surfaces, up to 60 minutes on carpet/upholstery
- Outdoors (perimeter): 30 minutes if no rain; longer if a heavy mist is rolling in
What "until dry" really means
When the product is applied wet, it's a fine suspension of active ingredient + water. As it dries, the active ingredient bonds to the surface in microscopic encapsulated particles. Wet = potential transfer. Dry = no transfer.
We tell our techs:
> If you can't see it shining, your dog can lay in it.
Specific situations
- Cats and birds are more sensitive to pyrethroids than dogs. We adjust products (Alpine WSG has no signal word) when sensitive pets are in the home.
- Fish tanks must be sealed off before any interior spray. Permethrin and lambda-cyhalothrin are highly toxic to fish.
- Bee colonies on your property: we never spray flowering plants during pollinator hours and we'll work with you on bee-safe alternatives.
- Bait gels (Advion, Maxforce) are non-volatile and dry essentially on contact — they're placed in cracks and crevices pets can't reach.
What we never use
We do not use:
- Aerosol "bombs" / foggers — they scatter roaches and bed bugs deeper into walls
- Older organophosphates (chlorpyrifos, diazinon) — banned for residential use
- Off-label rates of any product
