When you start a fight, you always need to know the characteristics of your enemy, his weaknesses and strengths. So here I’ll tell you everything you need to know about the cicada killer wasps and answer the most popular questions about them.

What Does a Cicada Killer Look Like?

Cicada killers are one of the largest species of wasps, adult female insects are up to 3 inches long.

They have segmented body in black and yellow stripes, the head and middle parts of the body are of a rust color. Their six legs’ color is from pale red to orange. Insects have yellow-brown tinted wings and antennae.

Where Do Cicada Killer Wasps Live?

These species create their nests in burrows in the ground. Their favorite places in populated areas are lawns and yards. They also like sidewalks, flowerbeds and sloped terrains. These wasps prefer to dig holes in sandy, soft and well-drained soil.

Cicada Killer Wasp Life Cycle

As in other insect species, males appear as adults first. They mate with females, emerging from the soil. After mating, females choose a place to create a burrow, which they supply with cicadas to feed the larvae. Cicadas stay alive but paralyzed by the venom of the wasp’s sting.

The female cicada killer makes a cell with one egg and two-three cicadas then seals the chamber. Pupation usually occurs in the spring and adult insects appear in June. Year by year, their number increases.

Cicada Killer Wasps Dangers

These insects destroy your lawn by burrowing nests in soil and creating tunnels, which can lead to serious results. Since cicada killers breed rapidly, they cause significant damage to lawns and bed flowers by their burrows.

These insects ruin your garden structure by digging and tunneling to lay the eggs and also destroy the roots system of your plants.

Although ground burrowing wasps are not aggressive, they sting when irritated, so your pets or kids playing in such a yard might be at risk too.

Signs of Cicada Killer Wasps Infestation

Here I’ll give you some tips on how to identify if you have cicada killer wasps on property:

  • the ground feels mushy when you step on it;
  • U-shaped tunnels in the ground with loose soil around the entrance;
  • small granular dirt mounds (2 to 5 inches high);
  • the hole of finger size at the foot of that mound.

How to Get Rid of Cicada Killer Wasps?

You need to understand that even when you don’t hear buzzing and flying insects, it doesn’t mean your territory is free from dirt digger wasps. These insects leave their eggs in nests, which you can’t see, so getting rid of ground digger wasps requires an integrated approach and includes several steps. So here is a small guide for cicada killer wasp removal.

Step 1: Eliminate the food source

Сicadas is the main food source for cicada killers. When they don’t have enough food, they will start searching for other areas. Adult cicadas feed on flower nectar and fermented sap from large trees.

So when you eliminate large plants and flowers from your area, that will make your garden less attractive for cicada killer infestation.

Step 2: Fertilize the soil

Cicada killers do not nest in the hydric ground, they prefer light-textured soil. So for successful cicada killer wasp control, you need to check your soil for adequate lime and fertilizer level and promote thick turf growth. Also, make sure the infested area receives 1 inch of water per week.

Step 3: Get rid of cicada killer wasps

After you finish two first steps, you need to find a suitable way how to destroy cicada killer nests. You can fill the burrows with water and wash away the piles of dirt surrounding them. Some owners recommend using boric acid or vinegar for that goal.

Natural decisions are easy, but they will be less effective than professional remedies. There are different products which help you to exterminate cicada killers:

  • wasp dust (it can be put onto each nest entrance);
  • liquid chemicals (you can fill the nest with them);
  • wasp aerosols (you can spray them at the nest entrances and directly onto the insects).

How to Prevent Cicada Killers in Future?

The best way to prevent cicada killer wasps in the future is to keep a well-maintained lawn, fertilized and wet enough, with no areas of bare soil. Thick turf and long grass in the middle of summer will also deter these burrowing insects from your area.

Best Cicada Killer Control Remedies

I already mentioned that despite the many natural ways for cicada killer wasp extermination, I prefer to trust checked and proven professional products. In this section, I will shortly review the top 3 of them.

FAQ

Do Cicada Killer Wasps Sting Humans?

Cicada killers use their large stinger for hunting for cicadas and they sting to paralyze their victim and feed to larvae. You need to work hard to provoke the female cicada killer wasp to sting you.

It will happen if you step on the insect with bare feet or try to catch it with bare hands. Male cicada killers may seem more aggressive defending their territory, although they can’t sting.

When Do Cicada Killer Wasps Return to Their Burrow?

A burrow of a cicada killer can contain up to 20 cells with 1 egg per cell. Egg hatches to larvae and feeds on cicadas. So the female cicada killer leaves the burrow to hunt for cicadas and bring them back to put into each cell with the egg.

What Attracts Cicada Killer Wasps?

Cicada killer wasps are attracted by well-drained, light texture sandy areas with sparse vegetation at the full sun. They also prefer areas with deciduous trees and flowers nearby, and of course with plenty of cicadas living there.

Does Vinegar Kill Ground Digger Wasps?

Any liquid that gets inside the cicada killer wasp holes helps to kill the larvae and prevents the appearance of the adult insects next year. In many reviews, they recommend mixing the water and vinegar for higher effectiveness. But vinegar itself won’t kill the insect on contact. It works only for flooding the nests and prevention of the next generation.

Final Words

If you enjoy the sounds of cicadas in the evening while sitting in your backyard, you should know that sooner or later, they will come – cicada killer wasps.
