Sanitation is the first and BEST step in getting rid of pests. If the problem still persists, if in the US, go to your local LESCO dealer and tell them what your problem is and they will instruct you on what products you want to use. You could start with Bi-Monthly insecticides treatments around your foundation with something such as Diazinon (4EC if available, may need a license to purchase though) and maybe initially, do the whole yard as well as the foundation. Most Lawn Care company's offer this service too if you rather someone else do this for you (advisable). Request a "Flea and Tick" control and this should take care of the problem. As far as interior, set the appropriate traps and a do an insecticide bombing of the whole house, again you can get this stuff at LESCO or Lowes or someplace like that. The reason I mention LESCO is that they offer professional grade products there.
If you have termites or other wood boring insects in your home, I believe since you, as a homeowner, are still able to get "Chlordane". (If not, there are other alternatives but Chlordane is just the best, but the most dangerous) Call around and see what you can find. What you would need to do is use this with a carrier, meaning that with a hand sprayer, mix the chemical with Vegetable oil or another type of non-smelling oil and spray all the affected surfaces in the basement. The insecticide is a water based chemical and the oil is what will "Carry" the pesticide into the wood to the pests. If you don't use some sort of organic oil and simply use water to mix it, once you spray it, the pesticide will simply stay on the surfaces and thus you will not get a good control.
Mice: They make a whole variety of things for control, traditional traps, glue traps, poisons, live traps, get a couple cats?
Cockroaches and Beetles: Again, sanitation is the answer, don't leave piles of cloths, newspapers and anything they could make a nest in and make sure to get rid of all crumbs and leftovers. Try to eliminate area's that are moist or hold moisture. After you have done your house cleaning, THEN set your Roach Motels out and poisons.
I cannot express to you the importance of doing these applications properly and mixed correctly for safely and effectiveness. AND again I would stress that it would probably be better to call in the professionals to rid yourself of the pests if you've exhausted all your efforts. Orkin, Rose, there's a ton of company's that specialize in this. If you still persist in doing it yourself, make some calls and talk to the pro's at least and ask them for the best plan of attack.
