“It’s Raining Insects!” Pests that Come Out During the Rainy Season


The rainy season has arrived and most of us are looking forward to cool and comfortable days and nights. While we stay inside our homes to keep ourselves dry, some insects are going back to business. You might not know it, but some of them are pests that are taking their time in destroying your valuables and your home! This means it is time to call the pest and termite control guys to solve this problem. Good thing there’s Topbest to do this service for you.

Here are some of the pests known to be active during the rainy season—just make sure not to let them cuddle with you during those cold nights!



The Palo Verde Root Borer (Derobrachus geminatus) is a type of a long-horn beetle in Southwestern America and Northern Mexico. They are brown or black in color and have wings. Though they come out in the summer to mate, these pests can also feed during the rainy season and can go for a month just by using their bodily reserves.



The Tarantula Hawk Wasp (Pepsini Sp.) is considered to be one of nature’s most creative predators. It is a type of spider wasp that hunts tarantulas by capturing, stinging, and eventually paralyzing its prey. Weird as it may sound, this is actually a means of reproduction for these insects. After the spider has been killed, a female tarantula hawk wasp will carefully make a hole in the spider’s abdomen so as not to damage the internal organs. She will then lay a single egg in the spider’s abdomen and cover up the hole. When the larva hatches, it will feed on the spider’s insides but avoid the vital organs to keep the spider alive for as long as possible. The larva will then pupate and will leave the tarantula’s body—then the cycle begins again.


The Tarantula Hawk wasp stings and though these stings are powerful, these insects won’t do so unless they are provoked.





Rain beetles (Plecomidae sp.) spend most of their lives underground. They come out only during the winter or when it’s rainy, hence its name. Their abdomens are hairy while their backs are smooth and glossy. These critters can be black or reddish brown in color. The rain beetle feeds on plant roots deep beneath the ground, and loves to fly around when it is raining.



Don’t be fooled by its delectable-sounding name! Red velvet mites or rain bugs (Trombiidium sp.) literally look like tiny creatures wrapped with bright red velvet. They are often mistaken for spiders and are parasites to other insects such as grasshoppers during their early stages of life. By the time they reach adulthood, they become active predators, eating smaller insects like ants and tinier mites.
