Here at Stockpickr.com, we track many of the latest activist situations for those interested in piggybacking the best activist investors.

This week, our activist ideas focus on small and mid-sized companies.

For example, Dru Schmitt wants shares of

Sunair Services

(SNR) - Get Report

sold, with the net proceeds distributed to shareholders. Schmitt also said he is considering options, including replacing the board with people who are "not self-interested or not willing to overlook the track record of Richard Rochon, Sunair's chairman, and his associates." Sunair Services provides lawn and pest control services to residential and commercial customers.

Palo Alto Investors wants Greg Noval to resign from the

Canadian Superior Energy

( SNG) board due to "various conflicts" that Palo Alto believes exist because Noval serves as executive chairman of the company and as chairman of Challenger Energy. Canadian Superior engages in the exploration, acquisition and production of oil and natural gas primarily in Western Canada and offshore Nova Scotia.
