Sorry guys. Had a reheasal dinner last night. Let me try to answer a few questions y'all have brought up.
I work for Mike's Pest Control in Lafourche parish. Gonzales might be a little too far for us.
You have to watch some companies. They will just go out and do a renewal without contacting anyone beforehand. This is because most people will not raise a stink about it, due to the fact that most just believe that this is how it is normally done. If someone doesn't like it, that co. will just send someone out again and to please the customer. Usually, if this is their practice, they do not care if you cancel. Less for them to worry about, I guess.
Most, if not all, warranty contracts have limits on them. Most are 5 years. Some can be longer, as we actually offer a 10 year. At which point when the warranty is up for renewal, the co. will inform the customer that a "booster" must be done to continue the warranty. All this is really is another treatment to the home. Pending on the size of your house, $500 doesn't sound too bad. $150 for your renewal is a tad high, but not too aggregious.
When a company treats a home, all insects that come into contact with the chemical will die. Problem is, when the chemical dries, only termites will be controlled. Spiders are the most common pest that most people will have. They are a little tougher to get rid of due to they can actually build webs around the areas that you have treated, inadvertently.
and a deadly earwig or two, which bother me more than the spiders as they crawl in your ear and eat their way through to the other side.
Sorry, but they don't do that.
Doing termite treatments yourself are fine. Only problem is that you might not be able to get the chemicals that companies can obtain. Not to mention you probably don't have the equipment to be able to handle a correct treatment. Termites are very easy to get rid of, but termite cos can keep them away longer. There are definitely exculsions on damage warranties, so be sure to ask your co. what they might be. Leaks in indoor piping, leaks in roofs, faulty gutters, and even cracks in slabs, which are obviously covered by a flooring of some sort. Outside, there could be a ton of things that can void your warranty. Be persistant and ask all the questions you can.
The co. that treated your house should have contacted you about the contract. If not, they might not have had any contact info on you, so your contract could be cancelled. Check with your builder. Keeping your slab visible is good whether you have a contract or not. This will undoubtedly help your co. or yourself if you go DIY.
I try not to badmouth any other companies, but Arrow is something else. I have no idea if what they do is a good job, but they are known for coming to the Lafourche/Terrebonne area and charging sometimes half of what other compaines can charge. There is NO WAY I can go to Baton Rouge and charge what they charge. I would lose money. PERIOD. It has risen a lot of pulses down here with most termite companies. Paying $400/5 years (booster listed above) doesn't sound too bad, but $184/yr for a renewal does.
Hope I have been of some help, and sorry for making this so long.
