I ran my own nuisance wildlife business for 16 years. I've trapped fur for 51. There is no comparison between the 2. When I first started I thought wow look at how much I'm making. The insurance is only part of it. Being an LLC is a must. I carried a million for $650 a year. You could get a rider for the other for million for just that job. However the contract would be the key. You'd have to have it ironclad to protect yourself. I did a job like that once. They had so many stipulaions. It took me 3 months of nearly daily meetings emails, or calls before I won the contract.
To make enough money to support your family you need to do everything. Bats were what I was known for. 3 story buildings. Slate roofs. 18 hp gas vaccum for cleanout of bat guano up to 5 ft deep in places alone was $8,000. On all structures removing animals required warranties.
I once did a bat job, exclusion, cleanout, and re-insulation that required I pay any help $35 an hr.
My best month was $37,500. My expenses that month was over $17,000. Before taxes.
My best money was made trapping ground moles. Most years I had 750 traps in the ground from thaw until freezeup. Try moving moles from 10 acres. I dealt with the hairy tail species. High population in small area. Sometimes as many as 50 in a half acre. Once had 30 dozen traps dropped shiped. I once made over$12,000 in one month trapping moles.
Wore out tracks fast. Most years I logged over 50,000 miles a year.
Self- employment tax at the end of the year is 15.5% of your net. NPAT (net profit after taxes) is considered good over 25%. Most years mine was 40%. Other guys I knew were at 20%
If you just dabbled in it the required business expenses would make it unprofitable.
Anyone ever want info on doing nuisance work let me know. I'm retired from that now. Last year I trapped for fur for the first time without also running my business.
