Pests & Facilities第 128 / 240 题
A restaurant has a persistent fly problem near the back door. Which combination best addresses it under IPM?
a.Leaving the door open longer so flies fly out
b.Installing self-closing doors/screens, using air curtains, and keeping garbage covered and areas clean
c.Only lighting a scented candle
d.Only spraying insecticide near the food
解析
Flies are controlled by blocking entry (self-closing doors, screens, air curtains) and removing what attracts them (covered garbage, clean drains, no food debris). Spraying near food causes chemical contamination, and open doors let more flies in. IPM combines exclusion and sanitation rather than relying on one quick fix.
