Palmetto bugs are one of the most resistant cockroach species on the planet. They can withstand high levels of radiation and can go without food for up to 40 days.
In fact, in addition to poisoning palmetto bugs, chemicals also poison other animals, plants, soil and humans. Also, be aware that in general, these cockroaches are able to resist chemical insecticides. The ideal is thus to use plants that the palmetto bugs hate such as catnip, mint, or laurel.
How to get rid of palmetto bugs?
To limit the invasion, we advise you to replace dead or decaying wood with fresh wood or a new layer of mulch. Cockroaches are looking for water, humidity and heat and will seek another environment more conducive to their development.
Also look outside for possible sources of food: garbage, soft fruit, leftover lunch on the garden table, food and your pet’s water bowl. In addition, remember to close the lid of your garbage cans tightly to prevent the insect from coming to help itself at nightfall.
You can then place bait near the areas where you spotted the palmetto bugs: near your terrace or near vegetation. Although the baits and sprays that you will find on the market will kill individuals, be aware that these techniques are not very effective. It will take time without convincing results.
