hi, everyone,
I am so happy that i can answer these question, my husband is Canadian,and he told me that i can use warm water mixed with dishwash detergent, and spread the area where you found those bugs once or twice a day, until you dont find any in your house, those bugs like humidity, you can find a lot aft the rain or when sun is down. so this is the best the time to spread your house and along the door to you backyard. i did it last summer and this spring, i did not find any in my house. or you can go to buy the spread"raid crowling bug kill ", but i think dishwash detergent is safe and no damager way and it is good for the envirment also. it does not cost you any extra money. good lucky!
