Not sure what kind of bugs your talking about, but if you mean spiders and bees you should hire an exterminator for regular visits. If you are referring to wood boring bugs like Powder Post Beetles you will have to strip the stain from the house and apply a good borate treatment and then re-stain. Carpenter Bees, even though they bore into the wood, will not be affected by borate since they do not digest the wood fiber. You will need a Bee Kit to dust any of their holes that you can see activity in. Call Mike at 866-670-3020 for more help.
