Product Overview

Bug Buster-O provides rapid knockdown of more than 100 listed plant pests. It is OMRI Listed for Organic Gardening and can be used on day of harvest. Pyrethrins will degrade very rapidly in the sunlight. To make sure of getting the best performance, total coverage of the plant is most important. Using good quality spraying equipment will provide the best direct contact and coverage for as many insects as possible.

Plant safety is an important consideration when using insecticides. However, it is not possible to evaluate the phytotoxicity of Bug Buster-O on numerous plant varieties that may react differently to insecticides in different growth stages or under varying environmental conditions. Before making widespread applications of Bug Buster-O, treat a limited number of plants and observe for phytotoxicity over a 10 day period.

Will Monterey Bug Buster-O get rid of lizards?

I have a horrible horrible fear of lizards. I am desperate for something to keep them away from my home..


Monterey Bug Buster-O is only labeled to get rid of insects. There are not any products on the market that are labeled to kill lizards since they are considered to be beneficial. However, lizards feed on insects so eliminating the insect population could help decrease the number of lizards you see in your yard.
