Thanks for your review. Cockroaches require a lot of work because they like to hide. In fact they will spend 95% of their lives hiding out and nesting. Looking for nests can be difficult without some good old fashioned detective skills. They can nest in stoves,microwaves,refrigerators,keyboards,calculators,lamps,outlets,smoke detectors,baseboards,walls,clocks,tiles,trim,baseboards,fans,toilets,vanities,sinks,dishwashers,knife blocks,etc....
One gravid female roach will produce 1 egg case (around 40 eggs per case) every 5o days. She is fertilized once and can then produce 5-6 egg cases ( 40 eggs per case ) during her lifespan. Therefore just one Ootheca ( egg case ) with a 50/ 50 mix of males and females under the correct conditions (20 x 40 eggs) could produce 800 roaches within a few months. Even if we assumed half this amount at 400 roaches that's still a nightmare to most people. These are the jobs which require the most intensive work and have become a joke within the industry because of the money which property managers are willing to pay for roach removal. Imagine with all those hiding places all the work involved to rid one unit of roaches properly. I average 3 hours to do 1 apartment and my competition may average 5-10 minutes if that. The approach is simple, guy walks in to the unit dabs roach bait in shelves hinges, and under sink then leaves. Roaches may or may not eat it then tenant comes home and the roaches are hiding. At night 1 or 2 come out and wallah nothing has changed whatsoever. Property manager is happy because they paid $20 to have the unit gelled. The pest control company is happy because they treated 50 units at $20 dollars each. The tenant still has roaches and is still not happy. Property manager calls me for advice I tell them the whole unit must be treated give them a cost they laugh go find even cheaper less effective solutions, the roaches are even more numerous and the tenant still has roaches.
I feel for people that are living in these conditions . For those of you out their living in apartments make the property management aware that you want your units treated by spraying cracks and crevices, waiting for roaches to emerge, mechanically removing roaches and then applying residual dust. Two weeks later returning to said apartment and re-treating for any recently emerged roaches. Roaches can be missed and egg cases will hatch. Another month later the place is treated again as insurance. Treatments should happen on a schedule and not be dependent upon whether one sees roaches or not because they hide and remember the sheer amount of devastation that 1 female roach can accomplish.
