A home has widespread, inaccessible drywood termite infestations throughout its framing and is scheduled for whole-structure (tent) fumigation. Which active ingredient is the fumigant used for this treatment, and what limitation must the applicator account for afterward?

• Borate (disodium octaborate), which leaves a long-lasting residual barrier in the treated wood
• Fipronil, applied as a continuous soil barrier that prevents re-entry for years
• Imidacloprid foam, which remains active in the galleries to stop future colonies
• Sulfuryl fluoride, which leaves no residual, so the structure is not protected against future re-infestation
• Pyrethrin aerosol, which provides a knockdown plus a several-month residual film

A technician finds an active termite colony confined entirely within a wooden window frame on the second floor of a house, with no mud tubes anywhere on the foundation and no connection to the soil. This biology is most consistent with which termite group?

• Drywood termites, which nest in the wood itself and do not require contact with soil or the ground
• Subterranean termites, which must maintain a connection to soil moisture
• Formosan subterranean termites, which build carton nests in soil
• Dampwood termites, which require continuously water-saturated wood in ground contact

During an inspection, an applicator finds small piles of distinctively six-sided fecal pellets on a windowsill beneath tiny holes in the wood above. These pellets are the diagnostic sign of which pest?

• Powderpost beetles, which leave fine flour-like dust
• Drywood termites, which push their six-sided fecal pellets out through kick-out holes
• Subterranean termites, which leave pellets inside their mud tubes
• Carpenter ants, which leave coarse fibrous sawdust
• Carpenter bees, which leave sawdust below round entrance holes
