Any product containing pyrethrins should do the trick. Spray flowerbeds, around retention walls, beneat rain catchers, etc. Prior to using pesticides, focus on exlusion. Seal all doors and Windows and make sure the Plumbing lines under your sink are properly sealed.
- Take preventative measures (get the bed away from walls, shake clothes before putting them on, don't walk around barefoot, don't store things in old closets with many cracks, check sheets before going to bed)
- Ask you physician to subscribe you something that is an antihistamine that can treat allergic responses. Some scientists says it works, others disagree, but it cannot harm to try it
- Go to you physician if you have been bitten and keep track of the development of the bite. As said, mine were minors and healed within two weeks (not even open wounds). There are many sorts of reactions to it.
