CHEMICAL CONTROL
Insecticides are most effective in getting rid of cockroaches when combined with sanitation and exclusion practices that limit the cockroach’s ability to establish or reinvade; chemical control alone will not solve the problem.
We use insecticides with extreme care. Indoor chemical control is warranted only if the cockroach population is established, but not for an incidental intruder or two.
GEL BAIT
For crack and crevice treatments, gel baits can be very effective. Apply gel using a bait gun or syringe in small dabs in cracks and crevices where cockroaches will find it.
While they are fresh, bait gels are very effective when placed in locations where they will be found by cockroaches. To remain effective, however, the gels need to be reapplied frequently.
Bait gels dehydrate in about 3 days when left in open air. Gels are most effective if applied in indoor areas.
