True or False: You should spray concrete when treating for fleas.

The correct answer is that it is false to say you should spray concrete when treating for fleas. Concrete surfaces do not provide a suitable environment for fleas, as fleas prefer moist, shaded areas with organic material for their life cycle to thrive. Spraying concrete would not effectively target the areas where fleas are likely to be hiding, such as in grass, soil, or underneath vegetation.

When treating for fleas, the focus should be on the areas where pets frequent or where there is debris and organic matter that can harbor fleas in various life stages. Thus, treating concrete essentially wastes pesticide and does not contribute to effective flea control.
