I thought ultrasonic things ran at higher frequencies like 38 to 40 kHz. 25kHz might be audible by younger women.

Maybe you can borrow an active crossover and try that first. Or order one from Marchand Electronics; they can configure the board for any desired frequency.

But, why not just try recording at 32ks/s rather than 44.1, 48k or higher. The recorder should have a brick wall filter for those higher frequencies.

On the other hand, maybe the problem occurs right in the microphone. Try different mics, maybe dynamic types with more limited bandwidth.
