The Pest my Parents want to protect :P:D:P

So apparently my little brother(23 years), Kaustubh, got breathless one day. His girlfriend, Isha, was around at the time and came running frantically to my parents. Obviously my parents got all nervous too and took him to the hospital. Turns out Lil Kaustubh has problems with the fumes from the pest control... So me in my deductive thinking vein got thinking and came up with this... If the objective of doing a pest control activity is to get rid of the pests, and Kaustubh has problems with it too... then he should be a pest right... :P:D
