Ohalos9: 6
הָיְתָה גָבוֹהַּ מִן הָאָרֶץ טֶפַח, טֻמְאָה תַחְתֶּיהָ, אוֹ בַבַּיִת, אוֹ בְתוֹכָהּ, אוֹ עַל גַּבָּהּ — הַכֹּל טָמֵא.
[If the hive] is located one handbreadth above the ground, and there is tumah below, [the hive], inside the house, or inside or above [the hive], everything becomes tamei.
