Bubojed, vrlo korisna životinja jer godišenje pojede oko 10 kilograma larvi štetnih insekata i tako smanjuje njihovu brojnost u zemlji. Posebna poslastica su mu gliste, a ne prašta ni sopstvenoj vrsti ako zaluta u njegov tunel. Osim toga što nam pripomažu jedući štetočine, krtice kopajući podzemne hodnike doprinose boljoj provetrenosti i mešanju zemlje, pa ipak su nepoželjne jer svojim aktivnostima, a stručnjaci kažu da znaju da iskopaju i do dve hiljade kvadratnih metara krtičnjaka, čime ne samo da narušavaju izgled dvorišta, bašte ili neke zelene površine, veći i oštećuje koren biljaka. Međutim, treba znati da se one, za razliku od slepog kučeta, ne hrane biljkama.
