Carbaryl is a great product that you can use to eliminate these wasps from your attic completely.
How do i get rid of wasps in my attic.
Cautiously dislodge the wasps nest from where it hangs.
The best way of getting rid of wasps naturally and cheaply is to discourage them from establishing nests in your compound.
You can either spray the nest with peppermint oil or lemon clove solution.
If the nest is a hanging nest make sure you purchase a spray with a projectile shot so that you can completely cover the nest with it.
Because they are a dangerous pest i would recommend calling the local orkin branch office and asking them to send over a highly trained orkin pest specialist.
You should also check the bee hive that is located in your attic.
Unfortunately when people get around them wasps are known to get aggressive.
Another way of destroying the nest is to squirt dishwashing liquid into the end of your hose pipe and run the water until suds appear.
Many people are allergic to their stings which makes them exponentially dangerous.
It is a good idea to spray the pesticide on the openings of your attic.
Spraying neem or rosemary oil onto the nest is another way to kill these insects naturally inside your house.
When it drops to the ground break it into pieces using the same stick and reapply your pesticide of choice on the inside of the pieces.
Use caulk or a similar sealant.
Seal off any entrances or exits into the area of the wall where the wasp nest is located.
Make sure that you know the entering and exiting part of their bee hives.
The key to control is to eliminating wasp nests before they get large.
Wasps never invade nests other than theirs and thus they will keep away from your house.
The orkin pest specialist will inspect and develop a customized solution backed by science that best meets your needs.
