Ladybugs most certainly do bite! We've been told this from customers ever since we opened our doors almost 20 years ago. Though most people think of ladybugs as being a beneficial insect, the Asian Lady Bug can be a nuisance pest as described in our Asian Ladybug Control article. Once inside, you'll have to treat with the PHANTOM AEROSOL get their numbers down till the spring. At that point you should do a good liquid treatment with the Cypermethrin to get them as they leave the structure. This will cut down on the numbers that return the following fall. At that time you'll need to treat again to keep them from coming back inside where they'll want to hibernate and harrass you all winter. Asian Ladybug bites will happen as you encounter them during this time so keeping them out in the fall is key. And in some cases it will take 1-2 years to completely be rid of them once your home is infested so hopefully you don't have that bad of an infestation just yet.
