The Top Pests That Eat Basil

There are various types of insects and animals that feed on basil leaves. Here are some common ones:


Slugs love moist environments; hence they thrive in damp weather conditions where they can easily move around with ease while leaving slime trails behind them. They typically leave large holes in the leaves when feeding as well as slimy trails all over the plant's surface.


Snails also love eating tender young shoots of basils especially those found at their base by digging into soil which puts even more pressure on an already stressed herb garden bed since it disrupts the root system leading to stunted growth. They also leave similar trails behind as slugs do when feeding.


Aphids are small soft-bodied insects usually green or black in color which cluster together under basal stem foliage , sucking sap from tender new growth causing wilting , distortion and yellowing of affected areas with possible development of mold if left untreated due mainly because aphid excretion contains sugar substances known for attracting ants who protect these bugs from natural predators including ladybugs (which feeds primarily on aphids),


Cutworms tend to chew through stems of young basil plants just above the soil level, causing them to wilt and eventually die. These pests are especially active during the night.

Spider Mites

Spider mites are tiny arachnids that feed on plant sap by piercing through leaf tissues with their mouthparts, thus leaving behind a white or yellow discoloration on leaves as well as fine webbing if conditions favor it. As they suck out liquid from basil leaves, it leads to severe damage including stunted growth and eventual death of affected plants if not treated immediately.

How To Prevent Pest Infestations

  • Apply Natural Repellants : You can repel slugs by placing copper tape around your herb plot since these slimy critters will get electrocuted trying cross this barrier. Snails hate sharp sand or egg shells placed at base of host plant stem because they cause physical discomfort when crawling on them leading to reduced activity levels
  • Introduce Predatory Insects : Ladybugs have been shown an effective biological control measures against aphids in many gardens.


In conclusion, preventing pests that eat Basil involves taking care right from planting stage. Even so , sometimes we need more assistance like natural repellants such copper tape , sand barriers etc..

What pests commonly eat basil plants?

There are several pests that can cause damage to basil plants, including aphids, spider mites, whiteflies, and slugs. Aphids are tiny insects that feed on the sap of the plant, causing wilting and yellowing of leaves. Spider mites also suck sap from the plant leaves and leave a fine webbing behind them. Whiteflies are small insects that fly around in large numbers and feed on the undersides of leaves. Slugs usually come out at night and leave slime trails while they munch on young seedlings or tender foliage.

To prevent these pesky creatures from devouring your basil harvests or killing off your beloved plants entirely there is a number of steps you can do to minimize their impact.

Firstly for aphids: Remove any damaged or infested parts immediately as this will limit further spreading otherwise if it's minor infestation then just spray with neem oil solution using cloth/brush; make sure you cover both sides of all affected leaves properly.

Secondly for spider-mites: Monitor humidity levels regularly because dust mite populations grow in dry environment hence wiping down surfaces with damp cloth three times per week is necessary alongwith spraying insecticidal soap solution throughout growing season to keep their population under control.

Thirdly for white-flies: Sticky traps can be used which attracts adult flies thereby helps reduce their overall population by capturing them before they lay eggs; additional use insecticide spray i.e., pyrethrin every 7-10 days after transplant will provide even better protection

Lastly slugs – set up copper barriers around garden beds as well as sprinkle diatomaceous earth mixed in water(1tbsp/gallon) directly over soil where slug activity seen during nighttime.

How do I identify pest damage on my basil plants?

Identifying pest damage early is crucial when it comes to saving your precious Basil crop ! Damage varies depending upon the pest. A few indicators of potential infestation are holes in leaves, discoloration, or wilting. Check for spider mites by holding a sheet of white paper under an affected leaf and tapping it; if you see tiny red dots moving around on the paper then you know your basil is infested with spidermites! Aphids can leave behind sticky excrement that attracts ants; they also curl or wilt leaves as plants suffer from dehydration due to sap loss while whitefly larvae cause yellowingand drying out of plant tissues.

While slugs may be more challenging to spot during daylight hours since they are nocturnal creatures but slimy trail left behind is a sure giveaway so keep an eye out for them after dark.

Can I prevent pests from eating my Basil plants?

Prevention is key when it comes to protecting your basil plants from pests. There are several steps that you can take to help deter them naturally such as planting marigolds alongside your basil which repels aphids and other insects making their way towards its companion crop!

Companion planting will also help attract beneficial insects like ladybugs who feed on aphids while intercropping dill/parsley with Basil discourages spider-mite activity & using floating row covers over seedlings/cuttings reduce chances of slug attack dramatically.

Additionally maintaining hygiene in garden area by clearing dead undergrowth/debris/ weeds regularly alongwith routine watering/spraying neem oil solution every fortnight would create an environment less hospitable for pesky critters !

What organic remedies should I use against pest attacks?

  2. Insecticidal Soap: mix dishwashing liquid with water ( 1 tablespoon of soap per 1 gallon) to make a safe solution that kills pests on contact without harming the environment as well

  3. Diatomaceous Earth: sprinkle this powder directly over soil and leaves to create lethal barriers which dehydrates/slows down pest activity in general.

  4. Garlic Spray: mince garlic cloves finely then soak them overnight in oil/water mix ( ratio – one cup of garlic : two cups water/oil). Strain the mixture through cheesecloth or filter and spray it onto plants every fortnight for great results!
