I AM HAVING A PROBLEM WITH WASP IN THE HOUSE OVER THE LAST WEEK. THERE HAVE BEEN A LEAST 10 I HAVE KILL. I CAN’T FIND A NEST BUT ONE OR TWO EVERY COUPLE DAYS ARE IN THE WINDOW IN THE FRONT AND BACK PICTURE WIDOWS. I CAN’T SEEM TO TELL HOW THEY ARE GETTING IN.
Identifying entry points will be the key to solving this problem if in fact have some getting into the home based on an established pattern. Here are some guidelines that might help resolve the problem.
First, understand that seeing 1-2 wasps inside a home during the summer is normal and no need for concern. But seeing several in any week means something is happening that needs to be addressed. If you saw 10 this past week, I’m fairly certain you either have a nest inside the home or you have a passage way they’re using which is indirectly leading some to your living space.
Second, if you have a nest in the home, there will be a very distinct pattern or flight path many wasps will be using during the day. If you take some time to stand outside your home from noon till dark and casually observe the home from afar, you might be able to locate an entry point they’re using. Pulling up a chair and bringing out a refreshing drink while watching one side of the home for 10-20 minutes is a good way to pass the time. Set up outside in the yard, say 15-25 feet away from the side of the home, and remain motionless when watching. If there is a nest present or being constructed in your home, some wasps will be active and you should be able to see them once you focus your attention to the house itself.
Third, after watching all four sides of the home, you should be able to locate one side which has unwanted wasp activity. This side will then need further attention to stop the invasion. The next step will depend largely on where you think they’re going once inside. If it’s an attic or crawl space, getting to the spot will be required to see if they have constructed a nest you can directly treat. If you locate a nest, directly treating it with one of the products we mention in our WASP CONTROL ARTICLE should take care of it immediately.
Lastly, if you’re not able to locate any side with activity, you’ll most likely have to contact a professional service company to come and inspect. With any luck they’ll be able to locate a key entry point and then offer some treatment options that will take care of the invasion. In most cases I’ve dealt with like this, if there is a wasp nest inside the home (like in a wall void, attic space or crawl space), directly treating it is the ideal way to resolve the problem. But in cases where I’ve seen them going up under siding or just entering cracks or crevices with no clear nest visible, I’ve used the DRIONE DUST applied to these areas combined with outside treatments of CYPERMETHRIN or INSECT REPELLENT and been able to keep them away. The point is you can stop this activity once you know more about just what is leading to them getting inside and in order to get that information, you’ll need to do some detective work.
