Hello John,
I imagine it would depend to what lengths you are prepared to go to for your in-house pest control, If you take the in-house route are you prepared to let your technician concentrate on his pest control duties or is there a possibility that they may be diverted to other duties as part of his contract hours?
Do you know of your needs with reference to IPM in your unit?
Do you have adequate information/training to manage the technician if he is a stand alone in case of emergencies?
Do you have the correct paperwork, monitoring forms and treatment reports ect ect available to you?
If not then you need to consider his complete wage packet plus appropriate training and set up costs if you cannot tempt a competently trained pest control technician to join your team, all this would at the very least meet the 22k bracket pa.
I you choose carefully and go for the smaller specialist pest control operator you could save considerably on those costs by contracting out. I am speaking as the owner of a small pest control business so I am somewhat biast but as an independant I can offer the advise that the large companies do not necessarily offer the best value for money.
I don`t know the area that you work in to offer you a suitable candidate but contact the BPCA if you are a regional/ national company they should be able to point you in the right direction.
Failing that please feel free to contact me direct and we can have a chat.
