This is a good question.

Boundary blow-up in finite time is considered in

A. Ulikowska, Structured Population Models in Metric Spaces, PhD thesis, Warsaw University, 2013:

https://depotuw.ceon.pl/bitstream/handle/item/388/Rozprawa.pdf?sequence=1

More to the point, see

C. La Chioma, Integro-Differential Problems..., Ph.D. thesis, 2003:

http://www1.mat.uniroma1.it/ricerca/dottorato/TESI/ARCHIVIO/lachiomaclaudia.pdf

See Theorem 3.1.15, which applies Perron's method. Another good place to check in this thesis is Lemma 4.2.3, page 94.
