Cockroaches can squeeze themselves through incredibly small and thin cracks; therefore, it is integral to optimal pest management to ensure that small cracks and areas of ingress are properly fixed and sealed.

To effectively get rid of cockroaches and help stop them from returning, it is recommended to do an annual check of all pipe fixtures. Where necessary, replace or reapply sealant around inlets and outlets.

Keep crawl spaces dry by ensuring enough ventilation to stop moisture build-up. Well-maintained homes are less likely to experience cockroach activity as they are more difficult to enter and have unhospitable environments for cockroaches.

Insecticides To Get Rid Of Cockroaches In Texas

Last but not least, it can often be necessary to use insecticides to get rid of existing cockroaches. One can use several different insecticides, each having its respective effectivity depending on the environment; let us take a look at the options available and their pros and cons.

  • Insecticide dusts
  • Insecticide sprays
  • Insecticide baits

Insecticide Dusts To Get Rid Of Cockroaches

Boric acid and diatomaceous earth are the two most common dust types used to eliminate cockroaches. These are spread around the edges of rooms and in crevices. They should only be lightly applied as a dusting, or the cockroaches will avoid them.

Boric acid is more effective than diatomaceous earth but should not be applied to surfaces where food is prepared. The cons to dust are that it can blow away if applied in areas where there is a draft, and pets may try to eat them.

Insecticide Sprays To Get Rid Of Cockroaches

Sprays may be great for flying bugs, and yes, while some cockroaches do fly, most tend to crawl. Sprays also won’t get into the small crevices and cracks or behind appliances and cupboards where cockroaches may be hiding.

Sprays and foggers are not very useful for getting rid of cockroaches and can also carry danger in being a fire hazard due to the flammability of some of the fogging agents.

Insecticide Baits To Get Rid Of Cockroaches

Baits are one of the most effective forms of insecticide for getting rid of cockroaches. There are also several varieties, from bait stations to gels and pastes.

They can be applied to small inconspicuous areas where cockroaches have been seen. Baits work, as the name suggests – the cockroaches eat the bait and will eventually die.

The only con, although also a possible pro is that death is not instantaneous; however, the cockroach may take bait residue back to its shelter, where it may poison others.

Plastic-covered baits are the most home-friendly, as pets and children can’t get at the poison bait. While using a gel is much more convenient as it can be inserted in hard-to-reach crevices, care must be taken so that pets and children can’t reach the bait.
