Why buy the refill concentrate?  The refill allows you to reuse your 16 oz bottle when its been used up, plus there's an eco-friendly advantage. Instead of buying another 16 oz bottle once you run out, you can reduce packaging by buying the refill, and you can recycle both aluminum containers once your finished with both...(or, you can reuse your 16 oz bottle as many times as you like by purchasing more refill concentrates.)  Can we say eco-friendly bug repellents inside and out? 

Note: This listing does not include the 16 oz SQUITO BAN® repellent spray, as pictured in the last two photos.  We offer another product bundle that includes both the SQUITO BAN® refill concentrate and the 16 oz SQUITO BAN® repellent spray.  For more information about SQUITO BAN®, please look at the SQUITO BAN® Natural Mosquito Repellent listing (4 oz or 16 oz).
