Severe Infestation to none
Cut or rip paper towel in pieces, wet it, then put the gel on it. Place them where the infestation is . Then spray soapy water on it to keep the gel moist daily. They are attracted to moist stuff. Vendetta plus works very fast and very, very well with Vendetta, plus they can not reproduce it has IGR. I had a severe infestation from a 2nd hand stove. The best Roach gels are the ones that have IGR so that the Roaches can not reproduce . You can also put flat glue traps down, too. It helps. It is better to use Roach gels than using Roach spray. Fill a spray bottle with dishwashing soap, and water is better. The soapy water suffocates the roaches, no chemicals. Mop and clean with white vinegar and water ,and also fill a spray bottle with white vinegar, dish washing liquid , and water to clean the house with. It gets the Roach odor out, and the roaches can not relocate their nest..
