¿Cucarachas?

Apparently, there are no bugs in Spain. Despite the warm afternoons and the large trash receptacles at the end of every block here in Barcelona, I haven’t seen a single bug in 4 weeks. Not on the sidewalk, or on my patio or in the dank, exposed brick cavern of the inoperable lift in the entryway to my apartment, no bugs. At home, at work, in cafes, on the train – it seems every window in the city is open and not a single bug ever makes its way inside. Anyone have some insight into this phenomenon? (Where’s my Uncle Sam when you need him?)
