Cynoff seemed to work for the large roaches but the little ones are still around!
It is normal to see the nymph roaches after spraying. Only the insects that actually come into contact with treated areas will be killed by Cynoff. Basically you have killed off the larger adult roaches with Cynoff WP but you still have egg cases that are hidden away and they will continue to hatch and you will see the smaller nymph or baby roaches. We recommend that you use an insect growth regulator such as Gentrol IGR to help halt the growth of the juvenile roaches. By halting the growth of the roaches you will be able to stop them from reaching sexual maturity which in turn will stop the prodution of new eggs. We also recommend that you use a roach bait gel such as Advion Roach Bait Gel to get rid of those roaches that hide in areas where cannot spray such as wall voids, cabinets, drawers and cupboards. You can purchase these two products together in our Roach Control Kit #1. Ants can also be controlled with a bait product. Advion Ant Bait Gel can be applied in areas where you see ant activity. The ants will eat the gel and return to the colony where they will feed the gel to the other ants, effectively wiping out the entire colony. It is very important to avoid spraying Cynoff in places where you apply the roach bait gel or the ant bait gel to avoid having the insects reject the bait.
