Q. I live in a multi-level townhouse. I've had a pest control company come out and all they did was spray the baseboards in all the rooms. The ants returned in less than a month. This question has to do with pest control technique, not how to hire a pest control professional.

A. In my experience, you can spray and spray all you want, but, eventually, the ants will be back. Not always, but most of the time. And the pest control companies LOVE this, because it means they get to come back too! If you REALLY want to solve the problem, you must find the source of the ants. Once you find the source, which will be their nest, you must eradicate the source. There are several pesticides on the market that will handle this. Yes, this can take some effort, and is time consuming, but it really is the best way to solve your ant problem. Can you find a pest control company that will do this? Probably, but it will cost you, one, because of the time involved, and two, because it cuts into their business to eliminate the problem. As I implied earlier, if they eliminate the problem, there's no reason for them to come back, which means less money for them.

Q. The only pests we have seen are spiders, and occasionally inside the house. I have seen things at Lowe's, but are they effective? Can they be sprayed inside and outside? What is a good price for hiring someone to do pest control?

A. Chances are that there are many effective products out there... In fact, many people don't realize that what pest control companies often use are products available to the every day homeowner. I'm not an expert on spider control, but you would very likely find a suitable product by contacting a couple companies as if you were interested in hiring them and then asking them what they use. By contacting 2 or 3 companies you will probably find a product that both works and is available. As far as hiring a pest control company goes, you should just contact a few and get their quote for your situation. Usually competition provides an easily determined market price. Some helpful guidelines to be thinking about when hiring a pest control pro can be found in the source section.

Q. I am considering to sign up a two year contract with the Southern Pest Control company for the lawn and termites treatment.
