red wasps in basement

So in the past week I have found red wasps in my basement.  I dont go back to this room very often but the past few times I have I have seen a couple wasps each time.  I kill them then the next time I go back there are two more.  I usually see them hanging around the window and its usually in the evening.  I cant find a nest anywhere outside around the window or in that room.  I have found and killed a total of 7 wasps inside.  I dont know what to do please help.

If you read through our post which talks about WASPS AROUND A PICTURE WINDOW, you'll see what we recommend doing. The bottom line is you must be able to locate their route of entry if you wish to stop the invasion. Based on how many you've seen, I'm sure there is either a nest on the home or they are foraging inside some space or void in the home which is connected to your basement. Regardless, you'll have to seal the entry point and in order to do this, you will first need to identify the exact spot. At that time you'll be able to tell which treatment option to employ and then once the activity stops, you'll be able to seal it up to prevent this from happening again.

So read through the following post and try to locate the spot where they're entering and once you do, a treatment program can be initiated. If you have further questions on how to proceed after you locate where they're most active, give us a call toll free at 1-800-877-7290.
