Similarly, when BD99 and DM-50EC are combined together in two different blends, their activity also enhances. As in the case of BD99, which has strong repellency to ants but week repellency to crickets. This effect is overwhelmed by the DM-50EC which is likewise D-50EC also better repellent to crickets as compared to BD99. The benefit of this blend is that both of the insecticides used in this blend are human and environment friendly. And working together, they possess synergist effect. Therefore, combining both of the insecticides worked together to possess both attributes that is repellency to ants and crickets increased.
The use of individual insecticides in the paint can possess the insect repellent qualities but it is suggested that the insecticides should be used in the form of blends rather than alone to have more favourable and long lasting effect. In case of blends, although the use of blend 1 (BD99 & D50-EC) and blend 2 (BD99 and DM-50EC) showed ideal result of repellency but human safety is our top priority. Therefore, it is suggested and wiser to use the insecticides belonging to a safer family or less toxic family to humans. Best Insecticidal paint Conclusion leads us to the following: As pyrethroid family is lesser toxic, hence the blend 2 (BD99 and DM-50EC) is more appropriate to use rather than the blend 1 (BD99 & D50-EC).
