Digital harassment sounds irritate animals and birds so they leave - for good! Sounds are not species-specific, so they are effective against all animals and birds, plus bats and rodents. PROGRAMMABLE - UNIQUE FOR EVERY SITUATION Choose any or all of eight harassment sounds, then set the volume, mute time between sounds, random play for hours of operation. EFFECTIVE BECAUSE IT CHANGES! Repeating cannons and pyrotechnics don't work - animals and birds quickly get used to the same sound. But CritterBlaster PRO features eight harassment sounds that can be programmed in hundreds of different combinations so pests can't acclimate to a fixed pattern.
