Pharaoh Ants live in colonies with their nests in concealed places, mainly in kitchens and bathrooms e.g.. in wall cracks, along pipes and around sockets.
A single ants nest may consist of several thousands of workers, which are 2-3mm long and yellowish brown, as well as several queens, unlike other ant species. Control of Pharaoh Ants requires a special formulation, since failure to control all the queens and workers can result in the colony surviving.
Biopren contains attractants and nutrients as well as an insect growth regulator which has no immediate killing effect, but prevents queens from laying eggs and causes disorders in the development of larvae. When Biopren is used, ant colonies die off in 12-14 weeks.

How To Use

  1. To use cut the top off the plastic pack along the dotted lines and peel back the tab and stick the bait station, opening uppermost, along ant runs or near to a nest.
  2. In a small kitchen or bathroom use 2-3 bait stations. For larger rooms one bait station every 5 square metres.
  3. After placing the baits you may temporarily notice more ants than before, because of the attractiveness the bait.
  4. Replace the bait once it becomes used up.
  5. To ensure complete control it is recommended that you keep the baits in place for at least 3 months, even if the ants disappear much sooner.
  6. Do not use any other insecticide treatment whilst baiting Pharaoh ants.
