It's the same old song and dance every year: your yard is infested with a myriad of bees and wasps. They annoy you and maybe even sting your dog. So you spray for them and happily watch them disappear...only to see them come back again next summer.
What is going on here? Well, you're taking care of the symptoms of the problem without treating the cause of the disease. Remember, there are billions of bees in the world and though they seem to disappear during winter, they always seem to come back in the summer, even after a dozen applications of bug spray.
What happens after winter disappears? New queen bees hatch and start looking for a new home. And if you have left your home or yard untouched, they are likely to move back into undisturbed hives or into comfortable living areas, such as under the eaves of your home. As a result, you'll once again have a yard full of bees and wasps.
As you can see, DIY spraying techniques are no good for long-term bee and wasp control. They might help take care of the problem one summer, but they won't get them out of your home and yard for good. That's why you need to hire a professional pest control expert.
What will they do? They will inspect your home, find a treatment method that works, spray the bees and wasps currently in your yard, and use dispersal methods that will keep them from ever moving back. You can't afford not to invest in these techniques.
