I remember watching a movie when I was about 3-7 (about 97-01). I remember two brothers getting a string factory from their dad who recently passed away. They then tried to fix up a house but couldn't due to a mouse. They even got a cat that should have been able to kill it, but didn't. They also tried a reputable rodent exterminator which didn't work. Eventually one of the brother's wives leaves him. I remember a rather large man eating a cockroach in a restaurant where one of the sons was a chef. The father was played by or looked like Gary Busey. The father left the sons a string right before he died. One had a pretty bushy mustache throughout the movie, too. Sorry things are out of order this is just off the top of my head.
