Bees that infest your home or other structures on your property are a nightmare. This is especially true if you are allergic to bees. You should never swat at a bee and never spray water at a bee. Bees are known to travel in swarms. Water will aggravate the swarm and you could receive bee stings that could cause you health problems and pain. Bees will enter your home through the smallest of cracks and build a hive in sub floors, attics or anywhere they find safe. Eliminating bee infestations is not as easy as one would think. You could fumigate the area but if you do not escape in time the bees could attack you.
Any professional exterminator will tell you that even coming close to a beehive will cause the bees to attack. You need to have a pest control company solve this problem. They are skilled and trained for such infestations. After the infestation is eliminated, you will need to have a pest management plan to prevent the bees from returning to the area. If the bees are in sub floors, the one thing you do not want to do is start ripping up floorboards, which will make the bees attack.
Pest control needs to be done by professional and licensed exterminators that use the proper methods and have the proper training. There are many different reasons for infestations which need to be determined before eliminating the infestation. It is not wise to try this yourself but if you do, make sure you know how and why the infestation began because it could reoccur. Call a licensed exterminator and have the job done by a professional that is certified and insured.
