I have been in business for 4.5 years and still struggle with the "sweet spot." This will be first full calendar year in business full time.
Starting out my prices were low, you have to pay for your experience and lower prices help you get work and gain experience. However, low prices are not sustainable unless you are doing this for beer money or you enjoy living in poverty. One of the convenience store chains in my area starts everyone off $17.50/hour. If I am buying equipment, driving to your house, and climbing on your roof; I'm going to make more than that an hour.
If you are charging customers you are a business and should be set up as one. This includes paying taxes.
------------------
Example: Karen sees a groundhog going under her shed and wants it gone. She is 35 minutes from your door and is 18 miles away. You are trapping for 7 days.
Lets say I'm charging $100 set up fee. . . .
Day 1- set up and you chat with her about the problem. She shows you a couple of other holes around the house. You are there an hour. You go home
Day 2- No catches.
Day 3- You haven't caught anything and you wonder why. You go back out and look around to see if the animal didn't dig next to your trap. Things look okay and you leave.
Day 4- No catches.
Day 5- Nothing yet, so you go back out and you see a dead groundhog in the road about a block away from her house. You make an adjustment and leave.
Day 6- Nothing
Day 7- Both you and Karen are sad that nothing was caught. You pull your traps and leave, or maybe you wait a day or so.

Time:
So, in this example you made 4 trips, you spent 1 full hour on set up, plus smaller chunks of time on reassessments. Let's say you spent a total of 2 hours onsite
35 minutes one way = 70 minutes round trip x 4 trips = ~4 hours 40 minutes of your time driving + 2 hours onsite = 6 hours 40 min of your time
Fuel:
I get ~17 miles/gallon
18 miles one way = 36 miles round trip. This is a bit more than 2 gallons/round trip x $3.85/gallon = $7.70/ round trip in fuel x 4 trips = $30.80 in total fuel costs
---------------
Your $100 set up fee:
$100.00 - $5.66 (6% sales tax in PA) = $94.34
$94.34- $30.80 (fuel) = $63.54
Sometimes I will get cantaloupe or produce to use with my commercial bait/ lure. $63.54- $2 = $61.54
$61.54 / 6 hours and 40 min = ~ $9.24/ hour BEFORE you pay any income tax
----
Obviously, if you catch the groundhog it will bump you up. If you charge $50/head
$150- $8.49 (6% sales tax in PA) =$141.51
$141.51- $30.80 (fuel) = $110.71
$110.71- bait = $108.71
$108.71 / 6 hours and 40 minutes = ~ $16.32/hr
------------------------------
Keep in mind you will have other expenses- buying traps, bait, insurance, vehicle maintenance, and etc. It costs money to stay in business!
