As already mentioned before on this blog, the termite pretreatment is a termite control method that is applied prior to the completion of a structure that is being constructed at the time of application. In a pretreatment, termite control chemicals (or pesticides belonging to the class of chemicals specifically termed termiticides) are applied to specific areas in the soil of a lot upon which the building being pretreated shall be erected. The goal is then to create a type of termite-preventing barrier around the very foundations of a home, making for better termite protection and lower chances of termite infestations for that structure in the future.
Now getting a pretreatment for your early termite control solution can be quite tricky, not least because a pretreatment may cost quite a lot. If you are getting your home pretreated, be sure to follow the first rule in searching for good termite control services: look for a company that has an excellent reputation and possibly even accreditation with an organisation such as the Better Business Bureau. Ask if the company is licensed, insured, and bonded, and also ask the company for references. You may also ask your friends and family if they know a reputable firm that can do the job for you, just in case any of them have had pretreatment as well.
The second thing to do is to keep in mind that termite pretreatments are meant to be repeated for each new building erected on your property. This means that you cannot reasonably expect the new pool house you just built to be covered by the pretreatment you got for your actual house: it obviously does not work that way. If you want the pool house to be protected as well, you need to get a separate termite control option for it, ideally a pretreatment at the time of construction along with a supplementary termite prevention method for post-construction.
Next, be aware that the price of pretreatments tends to vary widely across cases because of the differences in soil. Even in Arizona, soils may vary greatly across construction sites, leading to the need for different termiticides or pesticide mixtures to be used in different pretreatments. Some soils make it necessary for your termite prevention specialist to buy more expensive, powerfully-bonding termiticides. Others, on the other hand, require only regular pretreatment chemicals because the soil is cooperative. Conditions vary widely, so have your termite prevention specialist take a look at the place ahead of time.
This relates to the last piece of advice: you need a termite control specialist who can work well with your building contractor. This is because they shall be working together and need to be aware of things such as shifts in the soil or foundations, changes to the original building plans pertinent to the ground, etc.
