Pest Control

Pest Control is an Institute radiant quest in Fallout 4.

Detailed walkthrough
Speak with Dr. Alan Binet over at Robotics, at night he will be in his quarters. Agree to eliminate some feral ghouls causing problems for a synth scavenger team. Teleport to the location indicated on your Pip-Boy. Enter the location and engage the enemies within. Fight your way to the tagged enemy and kill it. Not all foes need be slain. Return to Binet. Quest could be repeated every next day after finished.

Locations
Upon receiving the quest the Sole Survivor will be sent to one of the following locations:
 * Jamaica Plain
 * Sunshine Tidings co-op
 * Four Leaf fishpacking plant
 * Poseidon Reservoir
 * Wicked Shipping Fleet Lockup
 * Croup Manor
 * College Square
 * National Guard training yard

Bugs

 * If already established as a Minuteman settlement, the quest target may show as Jamaica Plain (possibly other locations as well) settlers. Killing the targeted settlers doesn't seem to affect anything and the quest is completed as normal. However doing so will also potentially affect the standing of whatever companion you're with. This is the only way to complete this mission on consoles or by destroying the Institute. This can be done on PC though there are commands to bypass this, see below.
 * If the location you are sent to is a settlement this could trigger the targets to not exist as mentioned in the bug above. Upon arriving, the quest marker disappears with no targets to be shown. To fix this on PC type in the console or   (effect will be the same). This will complete the stage where the targets were to be destroyed, though were unable to. After this you will be able to hand the quest in and proceed to the next one. If this happens again, repeat the same console command as it uses the same console code for every location.
 * Another but violent way to solve this bug is simple start shooting at your settlers. After one-two deaths quest markers will appear on heads of remaining settlers and after killing everybody quest will proceed to next stage. So if this bug would be encountered on non-PC platform this way is the only one to deal with it.
