The graphic design was varied, as you've no doubt noted - some legacy designs, some nice modern pieces like the Fly and Moth spray cans, and that Fly Spray can, whcih wouldn't look out of place today.

More history:

By the 1940s, Watkins was the largest direct-sales company in the world, but soon began to decline. The demographics and buying habits of the United States had major shifts in the following decades, and the company did not keep pace. Watkins filed for bankruptcy protection in the 1970s, and was purchased by Minneapolis investor Irwin L. Jacobs in 1978.
